To investigate the clinical efficacy and advantages of a hybrid operating platform in the microsurgical clipping of intracranial aneurysms via keyhole craniotomy.

A retrospective analysis was conducted on the clinical data of 119 patients with intracranial aneurysms treated in hybrid operating rooms and conventional operating rooms at the Second Affiliated Hospital of Soochow University from January 2021 to August 2024. SPSS 26.0 statistical software was used to analyze the data, comparing the differences in clinical treatment outcomes between the two groups and evaluating the treatment and prognosis of patients in the hybrid and conventional surgery groups.

A total of 119 patients underwent keyhole microsurgical clipping for intracranial aneurysms, with 56 patients treated in the hybrid operating room and 63 in the conventional operating room. In the hybrid group, digital subtraction angiography(DSA)revealed 2 patients had residual aneurysm necks and 3 exhibited parent artery stenosis during surgery. After clip adjustment or antispasmodic therapy, second DSA results were normal. No recurrence of aneurysm was found during follow-up at 6 months and 12 months postoperatively. Conversely, in the conventional group, DSA performed one week postoperatively indicated 7 patients had residual aneurysms, 4 cases underwent aneurysm embolization during the follow-up period.

The utilization of a hybrid operating room facilitates intraoperative DSA during keyhole aneurysm clipping, potentially allowing for timely adjustments of the clip based on real-time imaging of the aneurysm, the clip itself, and the parent artery. This methodology appears to mitigate the risk of postoperative aneurysm remnants and stenosis of the parent artery.
