Retrograde iliofemoral endarterectomy facilitated by balloon angioplasty.

PURPOSE

The purpose of this study was to explore the feasibility of iliofemoral endarterectomy performed through a single groin incision.

METHODS

Thirty-two patients aged 34 to 75 years (mean age 63.4 years) with a male/female ratio of 20:12 underwent 36 lower extremity inflow reconstructions from July 1989 to September 1994. Surgical indications were for limb-threatening ischemia in 24 patients and for claudication in eight patients. The procedures were done for occlusive disease of the external iliac artery and common femoral artery with patients under either spinal (n = 24) or local (n = 12) anesthesia. Intraoperative balloon angioplasty with fluoroscopic guidance preceded open retrograde iliofemoral endarterectomy. Adjunctive procedures included 18 profundaplasties, eight femorofemoral, nine femoropopliteal, and one femorotibial bypasses.

RESULTS

Thirty-three of the 36 cases were initially successful. The three failures were in patients with extensive calcification. The mean follow-up has been 36.4 months, and the patency rate was 80.5% at 3 and 4 years. The four failures noted on follow-up were caused by three common iliac artery stenoses and one iliac system occlusion. The former group was successfully treated with balloon angioplasty/stent, and the latter patient required an aortofemoral bypass. No operative deaths or limb loss occurred in this series.

CONCLUSIONS

Retrograde iliofemoral endarterectomy facilitated by balloon angioplasty is a safe, easy-to-perform, and viable option for patients with combined external iliac artery and common femoral artery occlusive disease. Midterm results (36.4 months) are favorable, and most hemodynamic failures are easy to correct with standard endovascular techniques.
