Aim To evaluate feasibility, efficacy, and safety of popliteal access compared to tibial retrograde approach for management of chronic total occlusion of superficial femoral artery after failed antegrade recanalization. Patients and methods The study was carried out from January 2016 to April 2019 at Sohag University Hospitals on 30 patients experiencing chronic total occlusion of superficial femoral artery and underwent retrograde transpopliteal or transpedal approach after failed antegrade intervention. Technical success and procedure-related complications were evaluated and compared among patient groups. Results Popliteal access was performed in 14 patients, whereas pedal puncture was accessed in 16 patients. Mean age was 57 (50–64) and 63 (52–65) years in popliteal and pedal access groups, respectively. There were no significant differences in patient baseline characteristics. Arterial puncture was successful in pedal than popliteal access (94.4 vs. 92.9%, P=0.96). Technical success was higher in patients with pedal access than those with popliteal puncture (87.5 vs. 78.6%, P=0.19). Operative time was shorter in pedal access than popliteal access (90±35, 120±28 min, P=0.04). Time to achieve hemostasis was 12±4.6 and 5±1.7 min in popliteal and pedal access, respectively (P=0.022). Access-site hematoma was higher in popliteal access group than pedal access group (28.6 vs. 6.3%, respectively, P=0.042). Spasm of pedal vessels occurred in three (18.8%) patients, acute thrombosis in two (6.7%) patients, access-site occlusion in one (6.3%) patient, and wire perforation in two (12.5%) patients. Conclusion When antegrade revascularization fails, retrograde access offers another endovascular option to treat critical limb ischemia before going to open vascular surgery, especially in high surgical risk patients. When both popliteal and pedal approaches are available, pedal access procedure is more preferable as it is relatively easier with less puncture-site complication.
