The “Pull, Cast, and Fix” Technique for Bypass in the Midpopliteal (P2) Arterial Segment in Chronic Femoropopliteal Occlusions

Abstract

Femoropopliteal bypass operations can be difficult when the occlusive disease involves the superficial femoral artery and the popliteal arterial segment above the knee joint (supragenicular artery, P1). In case of lack of suitable vein graft or when the surgeon wishes to spare to infrapopliteal segment, the choice of the midpopliteal artery as anastomotic site becomes challenging because of its location. Moreover, totally endovascular recanalization procedures in such cases can be complex and demanding, whereas other reported hybrid revascularization techniques require advanced technical skills and raise significantly the cost. Therefore, we present our suggestion of a "pull, cast, and fix" technique to encounter these challenges and facilitate a successful bypass with a synthetic graft in the upper midpopliteal (P2) segment, combing a secure endarterectomy and anastomosis even under marginal visualization by means of securing the lumen with a soft feeding tube after the artery has been pulled via a Satinsky vascular clamp. Accordingly, the procedure is accomplished with placement of a flexible self-expandable stent in the midpopliteal artery through the synthetic graft.
