Popliteal access for iliofemoral occlusive disease in the office-based catheter laboratory.

Abstract

Objective: Popliteal access as an alternative to conventional femoral access has not been reported in the office-based catheter laboratory setting (OBL) and may be perceived to have higher risks. The purpose of this study was to evaluate the safety and efficacy of popliteal access for the endovascular treatment of iliofemoral arterial occlusive disease in an OBL setting.

Methods: From October 2018 to October 2023, a total of 1408 interventions for peripheral artery disease were performed in our OBL. A cohort of 27 popliteal access consecutive procedures for femoral and iliac artery occlusions were studied. All interventions were done using a micropuncture needle under ultrasound guidance. All patients were discharged 1 hour after completion of the procedure. Indications for popliteal access were presence of aortoiliac stent grafts, aortobifemoral or aortoiliac bypasses, difficult contralateral or antegrade femoral access, and flush superficial femoral artery occlusions. Procedures were determined to be successful upon complete resolution of the target lesions and safety was measured perioperatively and at 90 days. Patency was determined clinically, by arterial duplex examination, and by need for reintervention for ≤2 years.

Results: We performed 27 popliteal access procedures in 25 patients (21 complete femoral artery occlusions, 6 severe stenosis). Iliac disease was present in nine. Indications for popliteal access were existing aortoiliac stent graft in 11, aortobifemiliac bypass in 4, noncrossable iliac occlusions in 3, failed antegrade femoral access in 4, flush superficial femoral artery occlusion in 3, and bilateral common femoral artery disease precluding access in 2. Trans-Atlantic Inter-Society Consensus classification preoperatively was B, 4; C, 4; and D, 19. Treatments included atherectomy/balloon angioplasty and stent in 12, balloon angioplasty and stenting in 4, atherectomy/balloon angioplasty in 5, and balloon angioplasty alone in 6. Successful opening of occlusions occurred in 25 of 27 patients (92.5%). No complications or major adverse cardiac events occurred, except one asymptomatic small popliteal arteriovenous fistula. Of the 25 successful procedures, the duplex patency at 3, 6, and 12 months was 19/20 (95%), 11/15 (69.3%), and 11/13 (61%). Rutherford Classification improved from a preoperative value of >4 in 24 of 27 (89%) to a postoperative value of <2 at 1 month in 23 of 23 (100%), at 3 months in 19 of 20 (95%), at 6 months in 11 of 15 (69.3%), and at 12 months in 11 of 13 (61%). Freedom from reintervention at 3 months occurred in 19 of 20 (95%), at 6 months in 13 of 15 (86%), and at 12 months in 12 of 13 (79%).

Conclusions: Popliteal artery access for complex iliofemoral disease is safe and effective and should be considered as a valid alternative option in the OBL setting.
