Short-term outcome of primary stent graft for peripheral artery aneurysm in patients with Behçet disease.

Abstract

Endovascular treatment of peripheral artery aneurysms (PAAs) in patients with Behçet disease is controversial. We report a single-institution experience of primary stent graft repair of PAAs in Behçet patients. Behçet patients who had endovascular stent graft repair of PAAs at a single center between January 2012 and December 2018 were identified. Demographics, past medical history, cardiovascular risk profile, and perioperative details were analyzed. Twenty-two patients (mean age, 38 ± 7 years; 100% male) were included. The distribution of PAAs was external iliac artery in 2 (9%) patients, common femoral artery in 4 (18%) patients, superficial femoral artery in 15 (68%) patients, and above-knee popliteal artery in 1 (5%) patient. Pseudoaneurysm was diagnosed in five (23%) patients. We used antegrade access in the majority of patients (16 [73%]). Technical success was achieved in 21 (95%) patients. The mean hospital stay was 3 ± 2 days. There were no deaths or serious complications, and five (23%) patients experienced access site complications. The mean follow-up was 23 ± 11 months. The early primary and assisted primary patency rate was 91%. However, follow-up computed tomography angiography detected stent graft occlusion in six patients (27%). Stent graft for PAA in patients with Behçet disease had a high early patency rate and minimal morbidity. However, the complication and reintervention rates were high during follow-up, with low surgical conversion.
