主要研究背景及目的

方法

Forty-one consecutive patients with unruptured middle cerebral artery (MCA) bifurcation aneurysms were included in our study. Based on the appearances observed under the microscope, aneurysms were classified into two different types: thick-walled and thin-walled aneurysms. Preoperative computed tomographic angiography (CTA) was used for geometry reconstruction and CFD analysis.

结论

CFD may be a useful tool for discriminating the intraoperative appearance of cerebral aneurysms.

主要结果

Morphological and hemodynamic parameters were compared between the two groups. Eighteen aneurysms were classified as thick-walled atherosclerotic ones according to their intraoperative appearances. Compared with thin-walled aneurysms, aneurysms with atherosclerotic changes had larger geometry parameters (aneurysm depth, maximum height, diameter, aspect ratio, size ratio), lower wall shear stress (WSS), and larger low WSS area ratio (LSAR). Thick-walled aneurysms characterized by atherosclerotic changes are associated with low WSS and larger LSAR
