Revascularization Procedures for Chronic Lower Limb Ischaemia in TU Teaching Hospital

Abstract

A retrospective review of various revascularization procedures performed for the management of chronic lower limb ischaemia in Tribhuvan University Teaching Hospital (TUTH) during the last three and half years was done. A total of 37 revascularization procedures were done in 30 patients. Mean age of the patients was 53.10+15.34 (range 20-88) years. Except 3, all the patients were male. Atherosclerosis predominated as the cause of arterial occlusion. Superficial femoral artery was the commonest site of occlusion followed by external iliac artery. Femoropopliteal bypass was the commonest procedure done (62 per cent). Vascular prosthesis was used only in 7 patients, rest were managed using autogenous saphenous vein to bypass the occluded segment. Endarterectomy (10 per cent) and thrombectomy (8 per cent) were other procedures done for revascularization. There was 91% immediate limb salvage rate. Late limb salvage rate was 88% till the time of this writing. Key Words: Revascularization, chronic leg ischaemia, bypass, graft.
