Abstract:
Objective:To investigate the safety and efficacy of stent-assisted coil embolization in acute intracranial ruptured wide-necked aneurysms, and explore the safety of different antiplatelet drug regimens during perioperative period and the risk factors for prognoses.Methods:A perspective multicenter study was performed. A total of 417 patients with intracranial ruptured wide-necked aneurysms treated by stent-assisted coil embolization in Neurosurgery Departments of 4 hospitals (First Affiliated Hospital of Wenzhou Medical University [ n=41], Zhujiang Hospital of Southern Medical University [ n=111], Tangdu Hospital of Air Force Military Medical University [ n=100], and Xuanwu Hospital of Capital Medical University [ n=165]) from June 2017 to January 2020 were included. According to the different antiplatelet drugs regimens used in perioperative period, these patients were divided into loaded clopidogrel group ( n=87), loaded clopidogrel combined with aspirin group ( n=212), and tirofiban group ( n=118). Clinical data and perioperative complications of 3 groups were compared. Modified Rankin scale (mRS) was used to evaluate the prognoses of patients at discharge; differences of clinical data between the poor prognosis group and good prognosis group were compared. Independent risk factors for prognoses of patients with intracranial ruptured wide-necked aneurysms were analyzed by multivariate Logistic regression analysis. Receiver operating characteristic (ROC) curve was used to analyze the predictive values of risk factors in poor prognosis. Results:Degrees of aneurysm embolization immediately after surgery: Raymond grading I was noted in 351 patients (84.2%), grading II in 44 patients (10.6%), and grading III in 22 patients (5.2%). Perioperative complications were noted in 44 patients (10.6%), and death was noted in 4 (1%). Intraoperative thrombosis incidence of the loaded clopidogrel group, loaded clopidogrel combined with aspirin group and tirofiban group was 5.7% (5/87), 5.7% (12/212) and 0.8% (1/118); that in tirofiban group was significantly lower than that in the loaded clopidogrel group and loaded clopidogrel combined with aspirin group ( P<0.05). At discharge, 360 patients (86.3%) had good prognosis and 57 patients (13.7%) had poor prognosis. Multivariate Logistic regression analysis showed age≥60 years ( OR=3.407, 95% CI: 1.620-7.166, P=0.001), preoperative Hunt-Hess grading 3 ( OR=11.445, 95% CI: 3.584-36.547, P<0.001), preoperative Hunt-Hess grading 4 ( OR=88.951, 95% CI: 14.519-544.948, P<0.001), preoperative Hunt-Hess grading 5 ( OR=64.949, 95% CI: 12.809-329.325, P<0.001), and multiple stenting ( OR=4.709, 95% CI: 1.215-18.248, P=0.025) were independent risk factors for poor prognosis of these patients. ROC curves showed that area under the curve of combination of age, number of implanted stents, and preoperative Hunt-Hess grading in predicting poor prognosis of these patients was 0.821, with optimal diagnostic threshold of 0.500, sensitivity of 0.667, and specificity of 0.833. Conclusion:Stent-assisted coil embolization is safe and effective in acute intracranial ruptured wide-necked aneurysms; tirofiban is safe as perioperative antiplatelet drug; patients with old age, preoperative Hunt-Hess grading≥3, and multiple stents are prone to have poor prognosis.
