PURPOSE: To present long-term results obtained with endovascular abdominal aortic aneurysm (AAA) repair (EVAR) using the Zenith AAA endovascular graft from a single institution.
MATERIALS AND METHODS: Between 2007 and 2013, 95 consecutive patients (median age 77 years) underwent EVAR using Zenith. Data were prospectively collected and retrospectively analyzed until 2019. Primary outcomes were overall survival, freedom from AAA rupture, and freedom from AAA-related death. Secondary outcomes were freedom from late (> 30 days) re-intervention and surgical conversion, and freedom from aneurysm sac growth (> 5 mm).
RESULTS: The initial technical success rate was 96.8%. There were no deaths or intraoperative conversions. Overall survival at 1, 3, 5, and 10 years was 90.8%, 81.7%. 74.3%, and 57.2%, respectively. AAA rupture occurred in one patient (1.1%). Freedom from AAA-related death was 100% during the follow-up period. Freedom from aneurysm sac growth at 1, 3, 5, and 10 years was 98.8%, 86.4%, 76.9%, 53.0%, respectively. Freedom from late re-intervention and open surgical conversion at 1, 3, 5, and 10 years was 98.9%, 88.9%, 86.7, and 57.9%, respectively.
CONCLUSION: EVAR with Zenith endografts represents a safe and durable means of AAA repair, and risk of rupture and aneurysm-related death are low.
