Distal Superficial femoral artery (SFA) access

Abstract

An endovascular recanalization of chronic total occlusions (CTO) of the superficial femoral artery (SFA) can fail in a substantial number of cases. Retrograde approach for CTOs of the SFA, where an antegrade recanalization has failed, is an alternative technique. The classical transpopliteal recanalization technique however has some drawbacks. We developed another technique as an alternative to the classical transpopliteal approach for those cases where the SFA occlusion does not reach beyond the adductor canal. Retrograde access is attempted distal to the adductor canal (high P1-segment) by leaving the patient in a supine position.
