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.
