Actual incidence of cerebral infarction after thoracic endovascular aortic repair: a magnetic resonance imaging study.

ABSTRACT:

Objectives

The actual incidence of cerebral infarction (CI), including asymptomatic infarction, owing to thoracic endovascular aortic repair (TEVAR) has not been reported in detail. This study was performed to investigate the incidence of post-TEVAR CI by using diffusion-weighted magnetic resonance imaging (DW-MRI) and to determine the risk factors for both symptomatic and asymptomatic CI.

Methods

We examined 64 patients undergoing TEVAR at our institute between April 2017 and November 2020. Aortic atheroma was graded from 1 to 5 by preoperative computed tomography. Cerebral DW-MRIs were conducted 2 days after the procedure to diagnose postoperative CI.

Results

A total of 44 new foci were detected by post-interventional cerebral DW-MRI in 22 patients (34.4%). Only one
