Utility of four-dimensional computed tomography scan following endovascular aneurysm repair.

ABSTRACT:

Objective

The aim of this study was to investigate whether post-EVAR endoleak that cannot be diagnosed accurately by conventional computed tomography (CT) and color Doppler ultrasonography can be diagnosed using four-dimensional (4D)-CT.

Methods

A total of 461 patients that received endovascular aortic repair (EVAR) between 2011 and 2022 were included. From 2017, 4D-CT was done to post-EVAR patients with enlarged aneurysms that could not be explained by conventional CT or ultrasound results. The results of 4D-CT, whether or not additional treatment was performed, and clinical course over 6 months and 12 months after 4D-CT were retrospectively investigated.

Results

Among post-EVAR cases that were followed up by CT, enlarged aneurysm was observed in 75 cases (16.3%), of
