The role of fast approximate estimation displacement forces in prediction of stent-graft-related endoleaks after endovascular abdominal aortic aneurysm repair.

ABSTRACT:

Background

The flow-induced displacement force (DF) exerted on the stent-graft (SG) by the pulsatile blood flow has been considered a potential cause of sealing failure and endoleaks following endovascular aneurysm repair (EVAR). However, its clinical adoption remains limited by time-consuming computational simulations. This study aimed to validate whether rapid morphology-derived DF parameters, quantified from preoperative imaging, can predict stent-graft-related endoleaks (SGELs).

Methods

In this retrospective case-control study, we analyzed data from 217 patients who underwent EVAR between July 2011 and May 2020. Sixty-nine patients were diagnosed with SGEL while controls (n=148) were matched. DF parameters were derived from preoperative computed tomography angiography (C
