Mid-Term Outcomes of a Pre-Cannulated Iliac Branched Device in the Treatment of Abdominal Aortoiliac Aneurysms: A Retrospective Analysis from a Single Center

Abstract

The aim was to assess the mid-term results of the E-iliac branched device. Baseline and follow-up data of this monocentric retrospective cohort study including all consecutive patients with aortoiliac aneurysms treated with iliac branched devices between 2016 and 2023 were extracted from the hospital records. Preoperative and follow-up CT scans were analyzed regarding endoleaks, migration, aneurysm sac remodeling, and device patency. Overall, 50 devices were implanted in 38 patients with a median age of 69 (IQR 62-78) years, and 1.6 bridging stent grafts per vessel were implanted through transfemoral (22/50; 44%) or upper extremity access (28/50; 56%). Primary technical success and assisted technical success were 97% (37/38) and 100% (38/38), respectively. No migration, no type I or III endoleaks, no stroke, colonic ischemia, aneurysm rupture, or conversion during the early and mid-term follow-ups (11 months, IQR 5-26) were observed. Aneurysm sac enlargement or shrinkage was observed in 0% (0/38) and 16% (6/38) patients, respectively. E-iliac-related re-interventions were seen only during the early follow-up: two thrombectomies with bare-metal stent relining after thrombosis of the iliac limb. Bridging stent graft and E-iliac patency during the mid-term follow-up were 100%. E-iliac showed encouraging mid-term results in the treatment of aortoiliac aneurysms with high technical success and a low re-intervention rate.
