Objectives: While endovascular intervention is the recommended first option for management of common iliac artery (CIA) lesions, it lacks durable patency for Trans-Atlantic Inter-Society Consensus (TASC)-II C and D lesions involving the external iliac artery (EIA). Aorto-femoral bypass is a durable option but is unsuitable in patients with significant co-morbidities. Eversion endarterectomy provides an alternative to both endovascular and extensive open aortoiliac reconstruction for occlusive EIA disease.
Materials and methods: A single-center, retrospective review (2000-2020) of all patients undergoing eversion endarterectomy for EIA disease was undertaken. Demographic, clinical, operative and follow-up data were recorded.
Results: Fifty eversion endarterectomies were performed in 47 patients. The median age was 65.0 years (range 46-82) and 66.6% were male. Sixty-eight percent (n = 34) were ASA grade 3. Indications for intervention were disabling claudication (44%) and critical limb ischaemia (56%). Angiography demonstrated 22 TASC C and 28 TASC D lesions. The median follow-up was 18.5 months (range 0-149). The technical success rate was 100%, and 84% (n = 42) experienced an immediate symptomatic improvement. Primary and primary-assisted patency at one, three and five years was 86%, 82% and 74%, and 100%, 96% and 92%, respectively. The five-year limb salvage rate was 96%. Eight limbs required reintervention to maintain patency, either by open (n = 2), endovascular (n = 3) or hybrid approach (n = 3). Thirty-day mortality was 2% (n = 1) with 10% (n = 5) experiencing a procedure-related morbidity. All-cause mortality was 38% (n = 19) during the follow-up period.
Conclusions: Eversion endarterectomy is a safe, effective alternative treatment for occlusive EIA disease. This study reports durable patency at five years and low perioperative morbidity and mortality.
