Abstract

PURPOSE: To elucidate overall aspects of femoropopliteal bypass including patency rate, risk factors for patency and complications. METHOD: We analyzed 61 limbs with atherosclerosis in 57 patients underwent above-knee femoropopliteal bypass surgery from September 1994 to April 2000 retrospectively. The mean age of the patients was 65.3 years (31~80 yr.) Operative indications included disabling claudication (54%), resting pain (11.5%), ischemic gangrene (or ulceration) (34.4%). Associated risk factors were cerebrovascular accident (51%), diabetes mellitus (39%), coronary artery disease (32%), hypertension (30%), hyperlipidemia (16%). We used PTFE (polytetrafluoroethylene) synthetic graft in all cases. Adjunctive procedures were performed in 13 cases, which were iliac artery stent insertion in 7 cases, balloon dilatation in 4 cases, neurolysis in 1 case, profundaplasty in 1 case. RESULT: Overall 1, 3, 5-year primary and secondary graft patency rates were 83.8%, 73.0%, 71.3% and 98.0%, 85.0%, 75.0%. 17 postoperative complications occured including 10 cases of leg edema, 3 cases of myocardiac infarction, 3 cases of cerebral infarction, 1 case of pneumonia. In uni- and multivariate analysis, run off score was the only significant factor influencing primary graft patency rate (p=0.013), but risk factors such as DM, smoking, hyperlipidemia had no statistical significancy on the primary and the secondary graft patency rates.
CONCLUSION
We consider that run off score is the most important factor for predicting the graft patency as other studies verified.
