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 claudicator with complex lesions.
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 1165 patients underwent revascularization, 696 patients (mean follow–up 40±24 month) were treated because of intermittent claudication. After TASCII–A/B patients were excluded, 313 lesions only with femoropopliteal lesion (EVT vs. bypass =202 vs. 111) were analyzed by Kaplan–Meier methods and compared by the log rank test.
Overall complication rate was 3.5% and 14.4% in EVT and bypass surgery group (p<0.01). 1 and 5 years primary patencies were 82% and 74% in bypass surgery group; 68% and 51% 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 claudicator with TASC–C/D femoropoplieteal desease, EVT is also good option by the reason of lower complication rate and good secondary patency rate.
