Abstract

Although earlier studies showed higher values of wall shear stress in neurovascular conflict, hemodynamic patterns in the blood vessel after microvascular decompression are unknown. This study aimed to analyze the hemodynamic features of the offending artery preoperatively and postoperatively using computational fluid dynamics. We retrospectively analyzed 11 patients with trigeminal neuralgia who were surgically treated in our department during 2022. All patients underwent pre- and postoperative computed tomography angiography. Hemoscope software was used for computational fluid dynamics analysis. This analysis included 11 patients, median age 71 years (54.5% of female patients). Superior cerebellar artery was the most common offending vessel. In all 11 patients, elevated values of wall shear stress were found in the area of neurovascular contact. Postoperatively, with improvement of the patient clinical status, there was also a decrease in wall shear stress. Computational fluid dynamics analysis of offending vessels in trigeminal neuralgia can be a useful tool in preoperative planning and in assessing treatment outcomes and prognosis.

三叉神经痛患者的计算流体动力学初步研究。
虽然早期的研究表明神经血管冲突时壁剪切应力值较高,但微血管减压后血管的血流动力学模式尚不清楚。本研究旨在应用计算流体动力学方法分析犯动脉术前和术后的血流动力学特征。我们回顾性分析了2022年在我科手术治疗的11例三叉神经痛患者。所有患者均行术前和术后计算机断层血管造影。使用血流镜软件进行计算流体动力学分析。该分析包括11例患者,中位年龄71岁(54.5%为女性患者)。小脑上动脉是最常见的侵犯血管。在所有11例患者中,在神经血管接触区发现壁剪应力值升高。术后随着患者临床状况的改善,壁剪应力也有所下降。计算流体动力学分析的责任血管在三叉神经痛是一个有用的工具,在术前计划和评估治疗结果和预后。
