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 extraanatomic 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%.(Korean J Thoracic Cardiovas Surg 1994; 27:846-9)
