Angiographic runoff score as a predictor of outcome following femorocrural bypass surgery

Abstract

Objective: to evaluate the efficacy of the revised ad hoc scoring system in predicting the outcome of femorocrural bypass surgery.

Design: retrospective study.

Materials and methods: seventy-seven infrainguinal bypass procedures to the crural arteries were performed in 69 patients with critical leg ischaemia. Preoperative angiographic findings were graded according to the revised ad hoc scoring system and other preoperative angiographic measures.

Results: the revised ad hoc scores were valuable in predicting the outcome of these grafts. The status of the outflow artery throughout its length had a great impact on the long-term outcome in terms of secondary patency, leg salvage, patients alive with legs, and survival rates. In situ autogenous saphenous grafts achieved the best immediate and long-term results.

Conclusions: the revised ad hoc angiographic scoring method is useful in predicting the outcome of patients undergoing femorocrural arterial reconstruction. Patients with an outflow artery completely open throughout its length had excellent long-term results.
