Purpose

This study aimed to evaluate perioperative outcomes and long-term survical following EVAR explantation at a high-volume vascular center.

Methods

A retrospective review was conducted of all consecutive patients who underwent EVAR explantation between 2010 and 2024.

Results

death within 30 days of explant surgery was uncommon

78.6%

1-year survival

73%

3-year survival

64.9%

5-year survival

More results

Twenty-six patients underwent open EVAR explantation (mean age 75.7 ± 7.7 years, 92% male), with a median interval of 4.9 (IQR 1.8 - 8.5) years between index EVAR and conversion.

Indications included type II endoleak (31%), type I endoleak (35%), and graft infection or thrombosis (24%).

More results

Mean intensive care unit and total hospital stay was 10.0 ± 16.4 days and 17.3 ± 16.0 days, respectively.

Kaplan-Meier survival analysis demonstrated estimated survival rates of 78.6% at one year, 73.0% at three years, and 64.9% at five years.

Conclusion · 1 of 2

Open surgical conversion after EVAR carries substantial morbidity but, when performed electively in specialized centers, may be associated with acceptable perioperative mortality and durable long-term survival in selected patients.

Conclusion · 2 of 2

These findings highlight the importance of lifelong surveillance following EVAR, strict adherence to device instructions for use, and meticulous perioperative planning to optimize outcomes in this high-risk population.
