Objective To explore the related factors of occurrence of neurological complications after coil embolization for ruptured intracranial aneurysms (IA), and analyze the predictive efficiency of related factors by constructing Logistic regression model. Methods Totally 148 patients with ruptured IA who received treatment in the hospital were retrospectively studied from February 2021 to February 2024, and were treated with coil embolization. After 3 months of follow-up, the occurrence of postoperative neurological complications was counted. Logistic multivariate regression analysis was adopted to analyze the risk factors affecting the occurrence of postoperative neurological complications. ROC curve was applied to analyze the predictive efficiency of risk factors on the occurrence of postoperative neurological complications.Results During follow-up, 18 cases had neurological complications after surgery, with an incidence of 12.16% (18/148), and 130 cases did not have neurological complications after surgery, which were included in the neurological complication group (n=18) and the non-neurological complication group (n=130) respectively. Compared with the non-neurological complication group, the proportions of hypertension, wide-necked aneurysms and aneurysm bleb in the neurological complications group were higher (P<0.05). Logistic multivariate regression analysis suggested that hypertension and aneurysm bleb could independently affect the occurrence of postoperative neurological complications (P<0.05). ROC curve indicated that the area under the curve, 95%CI, sensitivity and specificity were 0.678, 0.542-0.814, 61.10% and 73.10% respectively. Conclusion Hypertension and aneurysm bleb are risk factors for postoperative neurological complications in patients with ruptured IA, and have certain predictive efficacy on postoperative neurological complications
