Summary: This study tested the safety and efficacy of using a percutaneous trans-venous femoropopliteal bypass to treat patients with long occlusions of the superficial femoral artery.

Conclusion: The study found that 100% of patients saw successful removal of lesions with no issues of calcification.

Abstract

Objective: This technical note describes a total percutaneous technique to perform ultrasound and fluoroscopy-assisted femoropopliteal bypass in long superficial femoral artery (SFA) lesions, using standard equipment, through a juxta-anatomical superficial femoral vein (SFV) tunnel.

Methods: Three percutaneous accesses were obtained under ultrasound guidance. The first was retrograde, with crossover maneuver, at the contralateral groin. The second was a proximal SFV-to-SFA stump puncture. The third was a distal popliteal artery-to-popliteal vein puncture. Through the described snaring and capture maneuvers, one single 0.018″ guide wire entered the femoral vein through the SFA stump and re-entered the popliteal artery distally. The fistulous tracts were then dilated and covered stents deployed and post-dilated.

Results: Three patients aged 68 ± 3 years and presenting Rutherford 4 chronic limb ischemia were treated with this technique. The mean SFA lesion length was 22.6 ± 3 cm. The mean procedure duration was 88 ± 18 min. No intraoperative complication occurred. The postoperative course was uneventful. In particular, no deep vein thrombosis occurred. Rutherford stage decreased from 4 to 1 in all patients, with a mean follow-up duration of 6.6 ± 2 months.

Conclusions: The main advantage of the technique is avoiding calcification issues by abandoning the trans-arterial recanalization approach for long calcified lesions. The second interest is its feasibility by simple endovascular means without any particular or dedicated device. However, longer follow-up is needed to assess safety and durability.
