Abstract

Background: The aim of the study was to present the results of a novel abdominal stent graft for patients with abdominal aortic aneurysm (AAA), through 2-year follow-up.

Methods: A single-center retrospective review with prospectively collected data was performed to assess the safety and effectiveness of the Minos Abdominal stent device for treating AAAs. We estimated technical success rate, in-hospital and 30-day mortality, and mortality at the end of follow-up as well as complication and reintervention rate in our study cohort. Follow-up imaging assessments consisted of computed tomography angiography at 1 and 6 months and yearly thereafter.

Results: A total of 52 patients (92% males; mean age, 74 ± 6 years) were enrolled with Minos Abdominal stent device from July 2020 until September 2023. Thirty one (60%) patients were asymptomatic while 21 (40%) were symptomatic. The technical success of the endovascular aortic repair was 95% (49 of 52 patients). In 5% (3 of 52) of the cases, cannulation of the contralateral limb was unsuccessful and was converted to aorto-uni-iliac graft. Two (4%) aortic related death were recorded during the 30-day period. The major adverse event rate was 3.8%. The overall mean follow-up was 30 ± 6 months; no aorta-related deaths or graft related complications were observed. Sac shrinkage (>5 mm) has been observed in 70% of patients.

Conclusions: Minos endoprosthesis seems to be safe, effective, and durable for treating AAA either in elective or emergent situations.
