Application of balloon-assisted technique for intraoperative rupture during intracranial aneurysm coil embolization / 国际脑血管病杂志

ABSTRACT

Objective:To investigate the effectiveness of balloon-assisted technique for the treatment of intraprocedural aneurysmal rupture (IAR) during intracranial aneurysm coil embolization and its impact on the clinical outcomes of patients.Methods:Patients with intracranial aneurysm received coil embolization and complicated with IAR in Xijing Hospital of Air Force Medical University from January 2013 to January 2019 were enrolled retrospectively. They were divided into balloon-assisted hemostasis group and rapid packing hemostasis group according to the methods of intraoperative hemostasis. The modified Rankin Scale was used to evaluate the clinical outcomes at 3-month postoperative follow-up. A score of 0-2 was defined as a good outcome. Multivariate logistic regression analysis was used to identify the independent influencing factors of clinical outcome. Results:A total of 77 patients with IAR were enrolled, of which 46 (59.74%) used balloon-assisted hemostasis, and 31 (40.26%) used rapid packing hemostasis. In 51 patients (66.23%) with 3-month follow-up data, 32 (62.75%) had good outcomes, and 19 (37.25%) had poor outcomes. Univariate analysis showed that there were significant differences in time from IAR to treatment, time from IAR to confirmed hemostasis, postoperative Fisher grade changes, and good outcomes between the balloon-assisted hemostasis group and the rapid packing hemostasis group (all P<0.05). There were significant differences in IAR treatment methods, time from IAR to treatment, time from IAR to confirmed hemostasis, and postoperative Fisher grade changes between the good outcome group and the poor outcome group (all P<0.05). Multivariate logistic regression analysis showed that balloon-assisted hemostasis (odds ratio 0.234, 95% confidence interval 0.056-0.990; P=0.048) and time from IAR to confirmed hemostasis ≤10 min (odds ratio 0.097, 95% confidence interval 0.024-0.397; P=0.001) were the independent protective factors of the good outcomes in patients with IAR. Conclusion:Using balloon-assisted technique to treat IAR during intracranial aneurysm coil embolization can achieve satisfactory hemostatic effect and improve the clinical outcomes of patients.
