Amputation might be beneficial in cases where no residual function of the limb is expected postoperatively. This implies major deficit of its neurovascular supply. Major nerve involvement may lead to preservation of a useless extremity that is worse than no limb at all [15]. For the lower limb, destruction of the tibial nerve is BTSA1 considered an indication for below-knee amputation since the functional result of the preservation of the limb is worse compared with the use of prosthesis. Modern prosthetics often provide better function than many “”successfully salvaged”" limbs. For the upper limb, even minimal

preservation of the movement and sensation might be beneficial for the patient (handle a wheel chair, https://www.selleckchem.com/products/i-bet151-gsk1210151a.html use computer systems etc) and generally provides better function compared with prosthesis. Non palpable VX-680 ic50 pulse of the radial or dorsalis pedis artery intraoperatively should lead to sonographic assessment of the vascular supply of the limb. If no venous return is seen on triplex, amputation should be strongly considered. Severe, irreparable vascular injury in an ischemic limb is another indication for amputation. Before performing an amputation, a vascular surgery consultation should be considered if available without delaying

the treatment decision [15, 16]. Improved techniques currently allow for revascularization of limbs that previously would have been unsalvageable. Revascularization is not without risk, however [9, 15]. Attempts to salvage a severely compromised limb may lead to metabolic overload and secondary organ failure. Comorbid medical conditions must also be considered before heading down a long road of multiple operations to save a limb [15]. Even though cases

with aggressive infection presenting with systemic complications due to gas gangrene of the limb are more likely to have more advanced local infection which precludes limb salvage, there is no evidence that amputation controls infection DCLK1 better than adequate wide surgical debridement. Therefore, in our patient the treatment decision for limb salvage was not influenced by the presence of systemic complications. It was rather based on the estimation of what is left behind after an adequate resection of all devitalized tissue. If limb salvage is attempted, one must take into account that postoperative daily surgical exploration might be necessary for several days until all necrotic tissue is removed. In cases of limb salvage after gas gangrene reported in the literature, serial debridement following initial surgery was necessary only in four patients including our case. This might indicate a more adequate initial operation in cases with limb preservation or a less aggressive form of disease in these patients [5–7].
