Exploration of the effect of morphology and location on hemodynamics of small aneurysms: a variable-controlled study based on two cases with tandem aneurysms.

ABSTRACT:

Introduction

Small aneurysms are usually treated with a flow diverter alone, without coils. However, some continue to exhibit incomplete occlusion after treatment, even after an extended period. This study aimed to investigate the effects of aneurysm morphology and location on the hemodynamic parameters related to poor outcomes.

Methods

Two patients with tandem aneurysms were enrolled. Flow diverter deployment was simulated, and preoperative and postoperative hemodynamics were analyzed using computational fluid dynamics. The preoperative and postoperative hemodynamics of the actual surgical plan were simulated using finite element analysis and computational fluid dynamics. The correlation between morphology, hemodynamics, and incomplete occlusion was evaluated by calculating
