Five-year reintervention after endovascular abdominal aortic aneurysm repair in the Vascular Quality Initiative.

ABSTRACT:

Objective

Patients who undergo endovascular abdominal aortic aneurysm repair (EVR) remain at risk for reintervention and rupture. We sought to define the 5-year rate of reintervention and rupture after EVR in the Vascular Quality Initiative (VQI).

Methods

We identified all patients in the VQI who underwent EVR from 2003 to 2015. We linked patients in the VQI to Medicare claims for long-term outcomes. We stratified patients on baseline clinical and procedural characteristics to identify those at risk for reintervention. Our primary outcomes were 5-year rates of reintervention and late aneurysm rupture after EVR. We assessed these with Kaplan-Meier survival estimation.

Results

We studied 12,911 patients who underwent EVR. The mean age was 75.5 years, 79.9% were male, 3.
