Abstract：Objective To evaluate the efficacy of surgical clipping assisted by CTA combined with 3D Slicer three-dimensional reconstruction technology for patients with intracranial aneurysms.Methods The clinical data of 24 patients with intracranial aneurysms treated by surgical clipping from January 2021 to December 2023 were retrospectively analyzed.Preoperatively,CTA data were imported into 3D Slicer software for three-dimensional reconstruction to analyze aneurysm characteristics,followed by the formulation of individualized surgical plans.Intraoperative findings served as the reference standard to assess the accuracy of preoperative planning.Results Based on intraoperative observations,preoperative predictions of aneurysm orientation,spatial relationships between aneurysms and hematomas,and the course of parent arteries were precise.Preoperative assessment of parent artery stenosis showed excellent agreement with intraoperative findings(κ=0.865;P<0.001).Preoperative prediction of aneurysm neck dissection difficulty demonstrated high consistency with intraoperative observations(κ=0.779;P<0.001).Postoperative cranial CT scans at 24 hours revealed no new hemorrhages,and cranial CTA at 7 days post-surgery showed no aneurysm recurrence.Intraoperative aneurysm rerupture occurred in one case,and postoperative infarction in the distal territory of the parent artery occurred in one case.Conclusion CTA combined with 3D Slicer three-dimensional reconstruction technology enables accurate evaluation of intracranial aneurysms and provides critical anatomical information for surgical clipping,which aids in reducing surgical complications.
