Abstract
Extra-anatomic bypass is indicated for the limb salvage of patients with threatened limb loss especially those who have high risk of infection and death after general anesthesia. We did extra-anatomic bypass procedure nineteen times over a seven year, two month period on sixteen patients. Their mean follow up period was 41.3 months. Male to female ratio was 7:1. Major complaints were resting pain[36.8%], claudication[31.6%], cyanosis[15.8%] and ulcerative change[15.8%]. Associated diseases were hypertension, tuberculosis, chronic renal failure, atrial fibrillation, complete heart block and laryngeal cancer. Postoperative patency rates were 76.9% at 1 year, 72.7% at 2 years and 70% at 3 years. Limb salvage rate was 78.9%. Postoperative mortality rate was 10.5%.
