Exploring the hemodynamic behavior of residual aneurysms after coiling and clipping: A computational flow dynamic analysis.

Background: Residual intracranial aneurysms post-clipping or coiling pose a poorly established risk of rupture. Computational fluid dynamic (CFD) offers insights into hemodynamic changes following such interventions. This study aims to assess hemodynamic parameters in residual aneurysms pre- and post-treatment with surgical clips or coils using CFD.

Sequential Hemodynamic Analysis of Ruptured Posterior Communicating Artery Aneurysms Treated With Coil Embolization and Delayed Flow Diversion.

Background And Objectives: Computational fluid dynamics has advanced our knowledge of the pathogenesis of intracranial aneurysms and the dynamic changes observed after treatment. Herein, we analyze hemodynamic changes throughout the intervention stages for ruptured posterior communicating artery (PComA) aneurysms, treated with acute coiling and delayed flow diversion (FD).

Methods: We performed a retrospective analysis of ruptured PComA aneurysms treated with the acute coiling and delayed FD strategy between June 2013 to November 2022, using 3-dimensional reconstructions of digital subtraction angiographies.
