Objective: We describe the technique and early results of lower extremity revascularization with total percutaneous bypass using extravascular placement of a stent graft (percutaneous prosthetic bypass). Methods: Patients with severe chronic limb threatening ischemia for whom open or endoluminal repair was either not feasible and or had failed were selected for a pilot study using percutaneous prosthetic bypass. The procedure requires placement of three introducer sheaths in the contralateral common femoral artery, and the ipsilateral proximal and distal superficial femoral arteries (SFAs). A guidewire is placed from the contralateral sheath to the ipsilateral popliteal artery via the two ipsilateral sheaths. Two self-expanding polytetrafluoroethylene-covered stents are then placed from the proximal SFA to the distal SFA. Results: A total of 30 bypasses were performed in 28 patients aged 71 ± 3 years. Of the 28 patients, 16 had severe claudication (Rutherford class 3; 53%) and 14 had critical ischemia (Rutherford class 4-6; 47%). The early results were excellent, with no deaths and one occlusion successfully treated with thrombolysis. No other complications requiring reintervention occurred. The mean follow-up was 25.4 months (range, 3-36 months). The 12- and 36-month Kaplan-Meier survival curve was 100% and 81%, respectively. The primary patency, secondary patency, and freedom from amputation rates were 75% and 75%, 78% and 75%, and 100% and 91%, respectively. Conclusions: For patients with long lesions and/or failed endovascular treatment, the described technique offers the advantage of a total percutaneous procedure with acceptable early results. If these favorable outcomes are confirmed in larger series with longer follow-up, percutaneous extravascular bypass of the SFA will represent a complementary tool for infrainguinal arterial repair.
