Abstract 12480: Long-term Outcomes of Endovascular Therapy versus Bypass Surgery in the Patients with Intermittent Claudication: Results from the RECANALISE Registry
Introduction: Although endovascular therapy (EVT) has advanced, few reported about the comparison between EVT and bypass surgery in the patients with intermittent claudication. Hypothesis: We assessed the hypothesis that EVT was safe and good result compared with bypass surgery. The purpose of this study was to evaluate long-term outcomes of EVT and bypass surgery in the patients with intermittent claudication.
Methods: We pooled data from patients enrolled in RECANALISE (REtrospective Comparative ANAlysis of the revascuLarization method for Infrainguinal artery disease, Surgical reconstraction and Endovascular treatment) registry, which is a multicenter registry in Japan. Of 1396 limbs (1165 patients) underwent EVT, 847 limbs (696 patients, Male73%, mean follow-up 1214±749 days) were treated because of intermittent claudication. They were divided into EVT group (693limbs) and bypass surgery group (154limbs). The primary and secondary patency rates of EVT and bypass surgery groups were analyzed by Kaplan-Meier methods and compared by the log rank test.
Results and Conclusions: Overall complication rate was 1.3% and 5.2% in EVT and bypass surgery group (p<0.01). 1 and 5 years primary patencies were 85% and 64% in bypass surgery group; 75% and 52% in EVT group. Although bypass surgery group had higher primary patency rate than EVT group by the log rank test (p<0.01), secondary patency rates were not different significantly between EVT and bypass surgery group. In conclusion, though bypass surgery is feasible treatment for the patients with intermittent claudication, EVT is also good option by the reason of lower complication rate and good secondary patency rate.
