Short-term Outcome of Primary Stent-graft for Peripheral Arterial Aneurysm in Patients with Behcet's Disease

Abstract Objectives Endovascular treatment of peripheral arterial aneurysms (PAA) in patients with Behcet's Disease is controversial. We report a single institution experience of primary stent-graft repair of PAA in Behcet's patients. Methods Behcet's patients who had endovascular stent-graft repair of PAA at a single center between January 2012 and December 2018 were identified. Demographics, past medical history, cardiovascular risk profile, and perioperative details were analyzed. Results Twenty-two patients (mean age 38±7, 100% males) were included. The distribution of PAAs was: external iliac artery (EIA) in two (9%) patients, common femoral artery (CFA) in four (18%) patients, superficial femoral artery (SFA) in 15 (68%) patients, and above knee popliteal artery (PA) in one (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 mortalities 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 CTA detected stent-graft occlusion in six patients (27%). Conclusion Stent-graft for PAA in patients with Behcet's had high early patency rate and minimally morbidity. However, the complications and re-intervention rates were high during the follow up with low surgical conversion.
