Malignancies can bleed and so confirmation of blood does not refute the possibility of a tumour; however arrhythmia forum buy generic bisoprolol on-line, as an isolated finding in the absence of other clues blood pressure 5332 order bisoprolol 10 mg without a prescription, this test should be sufficient to obviate the need for surgical exploration high pulse pressure young age buy 5 mg bisoprolol fast delivery. An alternative is to score a transverse groove in the nail at the proximal margin of the pigment and observe over a few weeks as the discoloration grows out blood pressure chart emergency cheap bisoprolol 10 mg fast delivery. If pigment continues to spread proximal to the groove heart attack is recognized by buy discount bisoprolol 10mg line, surgical exploration is warranted. The only treatment that can be offered is to relieve the pressure, and if dealt with soon after the injury this can be done by puncturing the nail, for instance with a hot pointed implement, cautery, small drill or punch biopsy. The possibility of an underlying fracture must be considered for larger haematomas [1]. It is stated that if more than 50% of the visible nail is affected, the nail plate should be removed. A comparison between two groups of children having exploration and repair or trephination alone showed fewer table 95. V Amputation of tip of digit, may include parts of matrix Chronic repetitive trauma 95. Nail bed laceration the nail bed may be lacerated by incisions, crush and avulsion injuries. Initially, the nail bed damage should be assessed by avulsion, and then the nail can be replaced after any necessary nail bed repair has been performed. The nail plate can be used as a useful splint [1]; a small window for drainage of blood and exudate is made in the nail [2]. More complicated injuries may require flap or graft reconstructions and, in some instances, vascularized composite nail grafts are used with microvascular anastomoses. If the distal tuft has been fractured to leave fragments of bone dispersed in the soft tissues, longterm morbidity may be prevented if these are removed [3]. Delayed trauma the most common kind of chronic deformity following an acute injury is a split nail or reduction in the length of the nail bed with consequent overcurvature of the tip of the nail. Cure of a split nail deformity is difficult, with only a modest chance of success [1]. Treatment entails excision of the nail bed and matrix scar and, in the case of a pterygium, a splitskin graft or part of the nail plate may be placed on the ventral aspect of the proximal nail fold to help prevent recurrence of the pterygium. It is important to keep the wounded aspects of nail bed or matrix separate from the overlying nail fold after surgery, and this is often best done by returning the nail plate after soaking it in antiseptic during the procedure. If treatment is required for a shortened distal phalanx with nail bed changes, there are two choices [2]: the entire nail can be phenolized, or a V­Y advancement flap can be performed based on two neurovascular pedicles. Surface change may include splitting of the nail into layers or a sandpapered effect, and the nail may acquire a brown longitudinal streak [5]. The most aggressive nail biting (onychotillomania/onychophagia) can produce subungual haemorrhage, strips of nail loss, with residual Chronic repetitive trauma Chronic repetitive trauma may take several forms. Nail biting the nail plate, periunguium and nail bed are all subject to nail biting and picking. Nail biting produces distinctive features, which are found in 60% of children, 45% of adolescents and 10% of adults [2]. Focal abnormalities, such as viral warts, are often a complication, whether as a cause or as a result of the Koebner effect after biting. Severe damage may be associated with self mutilating disorders such as Lesch­Nyhan syndrome. This can lead to bleeding and chronic paronychia with acute infective exacerbations. In cases associated with infection, osteomyelitis of the terminal phalanx can develop [8,9]. Subjects will sometimes deny nail biting and attribute the appearance to a disease that stops nail growth. Transverse grooves scored proximally in the nail plate will confirm that the nail is growing by moving distally with time. Trauma is sometimes inflicted by other nails, with pushing back of the proximal nail fold as part of a habit tic (see above). In more conscious forms of selfdamage, sharp instruments are used to produce dermatitis artefacta of the nail unit, and the nail fold is commonly preserved [10]. Where the patient acknowledges an element of self damage, they may comply with the use of paper surgical tape as a dressing over the tip of the digit 24 h a day for 2­3 months. In the first month, it may be helpful to combine the tape with moderate potency topical steroid to suppress any inflammation. Local antiseptics and antimicrobial ointments may help settle the infection secondary to nail unit damage. Antiseptics or treatments with the most bitter taste are often prescribed in the belief that this will discourage biting. Antidepressants [11] and behavioural therapy [12] have been used with some success in limited studies. Onychotillomania may be allied to parasitophobia when the patient picks off pieces claiming that they contain parasites [6]. A rough and irregular nail and nail fold may result with haemorrhage in the nail fold also. Trauma followed by secondary infection involving the matrix may make nail loss permanent or result in pterygium formation. The nail folds are sometimes bitten in addition to , or as a substitute Damage from nail manicure instruments Metal instruments, such as a nail file or scissors, wooden or plastic orange sticks, or nail whitener pencils may create acute or chronic injuries in the nail area. Onycholysis may result from using the sharp point for cleaning under the nail plate. Nails, however, are best cleaned with a nail brush and soap, because overzealous manicure, pushing back the cuticles, may result in white streaks across several nails. Cleaning around the nail with contaminated instruments may lead to acute or chronic paronychia. According to Brauer and Baran [1], it is not advisable to cut or clip the nail plate, as this produces a shearing action that weakens the natural layered structure and promotes fracturing and splitting. An emery board is preferred for shaping the fingernail by filing from the sides of the nail towards the centre. Trauma from footwear onychogryphosis and nail hypertrophy [1­5] Onychogryphosis is an acquired dystrophy usually affecting the great toenail, which is thickened, yellow and twisted. It is most commonly seen in the elderly often made worse because of difficulties in self care of the feet [1,2,4]. Trauma and biomechanical foot problems may, however, precipitate similar changes in middle age or earlier. Palliative treatment requires regular paring and trimming of the affected nails, usually by a podiatrist using nail clippers and a file or mechanical burr. Other causes of thickened nails include psoriasis, pityriasis rubra pilaris, Darier disease, fungal infections, pachyonychia congenita, congenital ectodermal defects and congenital malalignment of the great toenails [6]. As the nail becomes longer and thicker, damage from footwear becomes progressively more important. Nail hypertrophy implies thickening and increase in length, whereas onychogryphosis implies curvature also. Some cases of nail hypertrophy are intrinsic, and this applies especially to toenails other than the nail of the great toe. The nail becomes thick and circular in cross section instead of flat, and thus comes to resemble a claw. It is possible that the nail plate distortion produced by chronic untreated onychomycosis may be partly responsible for onychogryphosis at a later stage. In extreme cases, the free edge may press on or even reenter the soft tissues of the foot. Treatment of onychogryphosis and nail hypertrophy may be either radical or palliative. Radical treatment consists of surgical removal of the nail and matrix and is recommended in those the nail can ingrow on any of its four margins, although lateral ingrowing is the most common pattern and is usually found on the big toe. The soft tissue at the side of the nail (lateral nail fold) is penetrated by the edge of the nail plate, resulting in pain, inflammation and, later, the formation of granulation tissue [4]. Infection is not typically associated, although the combination of pain, redness and swelling with ooze will dispose to treatment with antibiotics. Penetration of the nail fold is often caused by spicules of nail at the edge of the nail plate which have been separated from the main portion of the nail. The main cause for the deformity is lateral compression of the toe due to illfitting footwear, and the main contributory cause is cutting the toenails in a halfcircle instead of straight across. Anatomical features, such as an abnormally long great toe and prominent lateral nail folds, are important in some cases. Sport, with the toe impacting on the inside of the shoe through kicking or other movements, can be a contributory factor. Nail can embed in the proximal nail fold when there is disturbance of nail growth, usually through trauma. The proximal aspect of the old nail then impacts on the ventral aspect of the proximal nail fold and this creates the same features of inflammation, ooze, swelling, redness and pain as seen when the lateral nail fold is affected. Proximal nail ingrowing is known as retronychia and is selflimiting over a matter of several months as eventually the older nail is shed. During that time, nothing effectively relieves the problem and avulsion is the treatment of choice. Management is conservative in most instances, with topical steroid and antiseptic preparations. Excess nail fold granulation tissue can also be a feature of amelanotic melanoma and reactions to medications such as retinoids, ciclosporin, antiretroviral drugs and chemotherapy [9­15]. The first essential is to insist that the patient wear shoes sufficiently wide, high and pliable to remove lateral pressure [16]. The patient must also be instructed to cut the nail straight across instead of in a semicircle. The nail must be allowed to grow until its edges are clear of the end of the toe before it is cut; this prevents the further formation of marginal spicules. In the early stages, the infection may be overcome by the application of antiseptics and by inserting a pledget of cottonwool under the edge of the nail. Taping the toe or applying plastic gutters between nail edge and nail fold are alternatives [17]. These can be supplemented with acrylic nail to build up a smooth surface able to push the nail fold away and relieve ingrowing [18]. Potent topical corticosteroids can help to diminish inflammation and suppress granulation tissue. They should, however, only be used after infection has been ruled out or is being actively managed. If the infection is more severe with local cellulitis, an appropriate systemic antibiotic should be administered. When granulation tissue forms this should be destroyed by cauterization with a silver nitrate stick. Removing the nail alone is likely to result in recurrence of ingrowing when the nail returns [20] and so should be combined with a curative procedure such as phenolization of the relevant part of the matrix [4,21]. Although surgical excision of the matrix can provide an excellent result, it is more dependent than phenolization on the skill of the practitioner. In large studies, phenol treatment results in a greater cure rate and less morbidity (see Nail surgery section) [21]. Several drugs have been implicated including retinoids (systemic and topical) [4,5­8], antiretroviral therapies (indinavir, lamivudine) [4,9­11], mitozanthrones [12], ciclosporin [13] and systemic 5 fluorouracil [14]. Plaster cast immobilization is one such condition, where poor application technique may result in peripheral nerve damage from mechanical compression [21]. Disease course and prognosis If local trauma is suspected, the cause should be addressed (nail spur in ingrowing toenail, surgical removal of foreign body, stopping nail manipulation in onychotillomania, etc. It bleeds easily, and the surface may become eroded by necrosis of the overlying epidermis. Glomus tumour Definition and nomenclature Glomus tumour, a benign tumour of the myoarterial glomus (see Chapter 137), is an important cause of severe pain under the nail [26]. Glomus tumours arise principally in the pulp or nail bed or matrix of the distal phalanx, where the glomus bodies of Masson are numerous. Pathology A solid glomus tumour is composed of clusters of glomus cells surrounding capillaries. Glomus cells are uniform and round with pale eosinophilic cytoplasm, and a centrally located round nucleus. Variations in temperature, especially cold, may trigger pain radiating to the shoulder. It offers the highest sensitivity and best assessment of the extent of the tumour. The signal behaviour varies with the histological nature (vascular, cellular, myxoid) of the lesion [32]. Recurrent symptoms can usually be attributed to small synchronous satellite lesions [34]. Two approaches are possible: the direct approach after nail plate avulsion through the nail bed or the matrix followed by meticulous repair [35,36] or the lateral approach on the volar aspect of the lateral nail fold. The latter gives a more restricted view of the tumour with a higher chance of incomplete excision compared with the transungual approach [27,37]. Differential diagnosis Differential diagnosis includes all causes of nail pain (Box 95. Complications and comorbidities Pressure of the glomus tumour on the underlying phalanx may induce bone erosion in 50% of cases [27,30]. Subungual exostosis Definition Subungual exostosis is an isolated slowgrowing benign osteochondral outgrowth from the distal phalanx. Most authors consider it to be a distinct clinicopathological entity [39], but some classify them with osteochondromas [40]. Disease course and prognosis Patients have been wrongly referred to psychiatrists due to misdiagnosed glomus tumour where no nail alteration was visible and no proper workup performed. In its early stages, the tumour may have a porcelain white hue with superficial telangiectases and a collarette surrounding its base.

Management There is generally no very effective treatment arteria sphenopalatina generic 10mg bisoprolol mastercard, reflecting the non inflammatory nature of the disease blood pressure 220 120 bisoprolol 10 mg overnight delivery. Corticosteroids may have some benefit but this is variable and often difficult to assess due to the intermittent nature of the neurological disease; other immunosuppressive agents are often disappointing. The avoidance of smoking and oral contraceptives, and treatment of hypertension and hyperlipidaemia (both of which are commonly present), are important. Thrombolytic agents and vasodilators have been used in the acute situation, and antiplatelet agents appear to be effective in the longer term [5]. Clinical features Presentation Persistent, very painful and often punchedout ulcerations of the legs, especially around the malleoli, in women are typical of atrophie blanche [6]. Healing results in a porcelainwhite scar, frequently surrounded by telangiectasia. Besides venous hypertension and antiphospholipid antibodyrelated syndromes, sickle cell ulcers can show the same porcelainwhite scar of atrophie blanche. Introduction and general description this syndrome is common as either an idiopathic or secondary syndrome [1]. Management Antiplatelet, anticoagulant and fibrinolytic therapies have been reported to be useful in this syndrome, as well as anabolic steroids such as danazol and stanozolol [2]. In patients with lupus and atrophie blanchelike lesions, antimalarial therapy may be effective. Rapid relief of pain has been reported with the use of intravenous immunoglobulins [8], postulated to be due to inhibition of the vasoconstrictor chemicals thromboxane A2 and endothelin which thereby improves perfusion. Lipoprostaglandin E1 has been used with good response in a patient with livedoid vasculitis and essential cryoglobulinaemia [9], but this may have been mediated by an effect on the cryoprotein levels, which fell dramatically. There are anecdotal reports of response to tetracyclines [10], and Epidemiology Age this syndrome is most common in young to middleaged women. Associated diseases One of the most commonly noted associations is with chronic venous hypertension and varicosities, although the atrophic scarring in this setting is not usually preceded by small painful ulcerations, nor with surrounding livedo reticularis. The skin lesions are usually the first feature, and may be the only manifestation over many years. Antiendothelial antibodies have also been demonstrated but are probably not the cause of the disease [4]. Circulating immune complexes, or deposition of immune complexes or complement, are not usually demonstrated [2,12]. Although there can be a prominent lymphocytic infiltrate in later lesions, especially around venules, true arteritis and leukocytoclasis are not found [4,13]. Abnormal mucin deposits, which may be thrombogenic, occur even in early lesions although they tend to be more apparent in later lesions [4,13]. Pathology the histological picture in Degos disease depends upon the duration of the lesion biopsied. Early lesions show a superficial and deep perivascular, perineural and periappendageal chronic inflammatory cell infiltrate [13]. Deep dermal vessels show endovascular inflammation, proliferation and thickening with thrombosis [14]. Mucin deposition is seen at all stages [2,3,13], and fibrin deposition may be demonstrated; fibrinoid necrosis of vessel walls may occur [14]. From a histopathological perspective, the presence of lymphocytes, which may be seen within the damaged vessel wall, is viewed as abnormal and has led to the classification of Degos disease as a lymphocytic vasculitis [15] although it is not documented that this is a primary abnormality. Between these stages there is a phase with neutrophilic and eosinophilic infiltrate around adnexae and a dense perivascular lymphocytic infiltrate [13]. The epidermis, initially showing a mild vacuolar reaction, becomes atrophic with slight scaling, resembling that seen in lichen sclerosus and corresponding with the typical porcelainwhite colour seen clinically. Panniculitis resembling that seen in lupus profundus has recently been reported [16]. Blood vessels are thickened and disorganized, with fibrinoid degeneration; platelet­fibrin thrombi are more prominent than in skin biopsy material. Renal changes include thickening of the afferent glomerular arterioles and of the capillary basement membrane. Epidemiology Incidence and prevalence It is rare; a review in 1995 suggested that about 120 cases had been reported [3]. Age It is mainly a disease that presents in young adults, although it can affect any age group [4]. Pathophysiology the pathogenesis probably involves abnormal coagulation, although the precise mechanism is uncertain. Platelet and fibrin thrombi are apparent in dermal, mesenteric and nervous system blood vessels, and both abnormal platelet aggregation and inhibition of fibrinolysis have been reported [4­6]. However, most patients have no clear evidence of a systemic coagulopathy, suggesting that the thrombotic tendency is at the microvascular level. They develop as crops over a period of time and are usually asymptomatic, although they may be preceded by slight burning. Skin lesions affect any site, but mainly the trunk and proximal limbs; the face, palms and soles are generally spared. Although they may evolve gradually, and the number of lesions may vary considerably, about 30­40 active lesions are usually present [5]. Oral mucosal lesions are rare but penile lesions may occur [18]; the bulbar conjunctiva is often affected by lesions, which appear as sharply demarcated avascular areas [3]. Early skin lesions are pink or red, domeshaped papules, usually 2­5 mm in size, but sometimes up to about 15 mm. Papules soon become necrotic and umbilicated with a central porcelainwhite pallor and scaling, and the pink oedematous border becomes telangiectatic. Most heal rather slowly to leave a small white scar, often surrounded by telangiectases, as in atrophie blanche. Gastrointestinal lesions are the most important as perforation of the gut is a cause of death [19]. Identical lesions have been described in cases of various connective tissue diseases [8­11] and in a patient with Crohn disease [20]. The characteristic features are usually hard to confuse with those of other syndromes. Patients in whom systemic disease precedes skin lesions may cause particular diagnostic problems. Systemic manifestations can develop years after the appearance of the skin lesions, including bowel perforation and peritonitis, thrombosis of the cerebral arteries, meningitis, encephalitis and myelitis [22]. Warfarin, dextrans, chloroquine, immunosuppressive agents and plasma exchange have all been tried. Surgery to treat intestinal perforation may resolve the acute situation but is difficult as there are usually multiple lesions, and there is no longterm benefit from this approach. Steroids do not help, although some benefit in neurological symptoms has been suggested. Aspirin, antiplatelet agents, fibrinolytic agents and pentoxifylline, alone or in combination, may lead to remission and are perhaps most effective in the cutaneous disease [2,3,4,7,23]. Introduction and general description Calcific uraemic arteriolopathy is a complication of renal failure and dialysis, associated with high mortality rates and characterized Key references 101. Thrombosed vessels are seen occasionally, presumably as a secondary effect as the calcification of smallvessel walls extends more widely than the thrombotic change or the extravascular calcification [3]. Epidemiology Clinical features Incidence and prevalence It is rare but appears to be increasing in prevalence [4]. Presentation Early lesions tend to present as painful purpuric plaques, often with a retiform or stellate pattern, and may show central necrosis. The abdomen, thigh and hips are typical sites but the breasts may be involved, and in some patients the disease is mainly acral. Uncommon sites include the penis and the tongue [5] as well as the muscles and internal organs [2]. Associated diseases It may very rarely occur in other situations, such as alcoholic liver disease, and occasionally after chemotherapy, in patients with normal renal function. Disease course and prognosis the prognosis is generally considered poor, with a mortality of 50­80%, although there are occasional reports of a more benign course [1]. Pathophysiology Most patients have secondary or tertiary hyperparathyroidism, although the disorder can rarely occur in some with primary hyperparathyroidism. An elevated calcium­phosphorus product is generally expected, but some authors have suggested that this may be present in only a third of cases. Use of vitamin D, or of calcium carbonate (used as a phosphate binder in chronic renal failure), are risk factors [3]. Vascular calcification induces a phenotypic switch of the vascular myofibroblast to one of an osteoprogenitor. Inhibitors of mineralization include parathormonerelated peptide (inhibited by vitamin D) and matrix Gla protein (inhibited by warfarin); fetuin A inhibits calcification but is inhibited by vitamin D. Thus vitamin D, a commonly used treatment in chronic renal failure, and warfarin may both provoke this process. It is felt that tensile stress and vascular stasis within calcified areas may also play a part by creating tissue ischaemia. Investigations A deep skin biopsy for histopathology is usually undertaken to confirm the diagnosis. Blood tests include creatinine and urea, liver function tests, calcium, phosphate and parathyroid hormone. Management Parathyroidectomy has been cited as effective, but there is clearly a bias in patient selection for this procedure towards those who can tolerate the procedure and who are therefore a relatively healthy subgroup. Reduction of the calcium­phosphorus product when elevated is recommended (using lowcalcium dialysate fluids and noncalcium oral phosphate binders), as is good wound care and attention to possible accompanying infection, which is a common cause of death. Newer treatments that may influence the outcome of this disorder include sodium thiosulphate [6], which increases the solubility of calcium deposits and has an antioxidant function that may improve endothelial cell function, and cinacalcet hydrochloride [7], which is a calcimimetic therapy that suppresses levels of parathyroid hormone. Logically, cinacalcet should be most useful in patients with hyperparathyroidism, and sodium thiosulphate in those patients without (or in whom it is controlled). Hyperbaric oxygen, skin grafting and iloprost infusions can be useful adjuncts in the management of this condition [8]. Predisposing factors One large institutional study showed that, compared with other patients on dialysis, risk factors included obesity, liver disease, corticosteroid use, elevated calcium­phosphate product and elevated aluminium levels [1]. Hypoalbuminuria (or albumin infusions), recent rapid weight loss, protein C or protein S deficiency, warfarin treatment and hypotension have also been implicated as risk factors. Pathology Pathologically, there is calcification in the medial layer of the wall of small subcutaneous vessels, with necrosis of overlying tissue [1,2,3].

Prevention of infection pulse blood pressure monitor purchase cheap bisoprolol online, particularly lymphangitis/cellulitis arrhythmia potassium discount bisoprolol 10mg, is crucial to the control of lymphoedema heart attack 34 years old buy 5 mg bisoprolol overnight delivery. Care of the skin prehypertension is bullshit buy bisoprolol online pills, good hygiene hypertension jnc8 cheap bisoprolol 5mg visa, control of tinea pedis and good antisepsis following abrasions and minor wounds are important in reducing the risk of cellulitis, as maintenance of skin integrity and an effective barrier will reduce the entry of microorganisms. Part 9: Vascular Massage (manual lymphatic drainage therapy) Massage is an important component of treatment, particularly for midline lymphoedema where there are few alternatives [2]. This facilitates the drainage of lymph via lymphatic vessels/pathways that have been stimulated by the massage technique. Tissue movement must be gentle if it is to stimulate lymph flow without increasing blood flow [7]. Dynamic muscle contractions (isotonic exercises) encourage both passive (movement of lymph along tissue planes or through noncontractile lymphatics) and active (increased contractility and therefore propulsion of lymph within contractile lymphatics) phases of lymph drainage. Breathing, postural exercise, elevation and rest Breathing and postural exercises are important, particularly for clearance of lymph from the thorax and abdomen. Without the dispersal of truncal lymph, more peripheral limb oedema will not drain. Elevation per se does nothing to improve lymph drainage, but lowering venous pressure (and therefore filtration) can help to reduce swelling. Many patients with lymphoedema are overweight because of morbid obesity as well as fluid retention. Excessive weight gain is likely to impair lymph drainage in the same way as it impairs venous drainage, and obesity reduces mobility (and therefore exercise). Control of weight in combination with physical treatment may be sufficient to resolve oedema completely in some patients. Once intensive treatment is complete, maintenance treatment with hosiery is commenced immediately. While decongestive lymphatic therapy has become accepted first line therapy, evidence for best treatment is weak [16]. Diuretics alone demonstrate minimal improvement in lymphoedema, as their mode of action is to reduce capillary filtration by a reduction in circulating blood volume. Paroven (an oxerutin) and coumarin (a benzopyrone) have been trialled in lymphoedema and may create a small reduction in limb volume by reducing vascular permeability and thus the amount of fluid forming in the subcutaneous tissues. However, this has been shown to be of little clinical benefit to the patient [17]. More recent animal studies have incorporated growth factors with lymph node transfer surgical methods. Research is currently being undertaken to optimize growth factor delivery and human trials in patients with secondary lymphoedema should commence in the near future [23]. Surgical options Surgery has a specific role in the management of lymphoedema [24]. It is of value in limb lymphoedema in a few patients in whom, even after conservative treatment, the size and weight of a limb inhibit its use or interferes with mobility. Surgery involves either removing excessive tissue or bypassing local lymphatic defects. It is popular amongst surgeons as it is performed under local anaesthetic and the surgical incisions are small. Postoperative complications include lymphatic vessel occlusion, possibly due to thrombus formation within the lumen [27]. Postoperative results (within 1 year of surgery) vary greatly between centres, with limb volume reductions of 4­67% [28,29]. The development of imaging techniques could provide a tool to answer the question of its place in lymphatic treatment strategies. Lymph node transfer surgery Autologous transplantation of normal lymphatic tissue within a local or free flap to a site deficient of lymph nodes and vessels has been performed. The rationale is that the transplant of normal lymph nodes could encourage and improve lymphatic drainage in a previously oedematous region. Few surgeons seem to be performing this type of surgery but reported results appear encouraging, with one case series suggesting 40% of patients were cured of their lymphoedema [30]. One important concern to raise with this type of surgery is that it relies on the transfer of normal lymph nodes in order to improve lymphatic drainage. This concern is supported by reports of donor site lymphatic vessel dysfunction in patients undergoing microvascular lymph node transfer surgery for cancerrelated lymphoedema [31]. They are now rarely utilized as the postoperative complications can be disastrous. Undercutting of the skin allows the removal of additional tissue (Homans procedure). This procedure is preferred to circumferential excision and skin grafting (Charles procedure) or to the addition of inrolling of a skin flap (Thompson buried dermis flap operation). Postoperative complications include skin transplant necrosis, poor cosmetic results and worsening lymphoedema distal to the surgical site. None of the excisional procedures have curative potential as all chances of restoring effective lymphatic transport have been surgically removed. Volume reduction may be achieved through tissue reduction, but not through lymphatic drainage improvement. The indications for this type of surgery should be restricted to rare cases lacking alternative conservative or surgical treatment options. The exceptions to this rule are cases of genital or eyelid lymphoedema, where reduction/debulking surgery is used sooner rather than later [26]. Part 9: Vascular Liposuction Chronic lymphoedema may be associated with fatty tissue deposition in some patients, although the mechanisms of this are not fully understood. Excess adipose tissue will not respond to decongestive lymphoedema treatments, anastomosis surgery or lymph node transfer procedures. Liposuction creates significant volume reduction in therapyresistant lymphoedema of the extremities, when combined with lifelong compression therapy [32]. This adjunctive therapy is used in compliant patients willing to wear lifelong compression garments. However, liposuction has been shown to create a longterm volume reduction of 100% in compliant patients followed for up to 17 years [33]. Liposuction techniques, although not curative, offer an effective symptomatic treatment.
