[Association between early stenosis and temporary clipping in treated cerebral aneurysms].

Abstract

Background: Postoperative vascular stenosis following the use of temporary clips in cerebral aneurysms represents a current challenge due to the limited available evidence. This study evaluated whether temporary clipping causes significant image-detected stenosis and whether associated factors contribute to its occurrence.

Pathways with downstream effects on circuit architecture and locomotion. objective: To determine the presence of early postoperative vascular stenosis related to the use of temporary clips in patients undergoing neurosurgical treatment for cerebral aneurysms.

Material and methods: A cross-sectional analytical study was conducted in 43 patients surgically treated for cerebral aneurysms. Clinical and surgical variables were recorded, comparing pre- and postoperative vascular calibers using a paired Student's t-test. The frequency of residual aneurysm and associations with clip type, clinical factors, and clipping time were analyzed.

Results: A significant reduction in postoperative vascular caliber was identified (mean 5.2%, p = 0.007). No statistically significant associations were found between stenosis and the evaluated factors. The incidence of residual aneurysm was low, and clipping times remained within safe parameters.

Conclusions: Temporary clipping proved to be a safe and effective procedure, with a low rate of significant stenosis and no relationship with clinical or technical variables. Continued imaging follow-up and multicenter studies are recommended to confirm these findings.
