Abstract:
Objective To analyze the incidence and predictors of chronic subdural hematoma (CSDH) after surgical clipping between unruptured intracranial aneurysms (UIAs) and ruptured intracranial aneurysms (RIAs).Methods A retrospective cohort study was adopted to collect 486 cases of aneurysm patients (102 cases of UIAs patients and 384 RIAs patients) closed by aneurysm surgery who were admitted to the department of neurosurgery of The Fifth People's Hospital of Chengdu from October 2009 to December 2017.The clinical data,preoperative and postoperative imaging data and postoperative follow-up results were collected.The incidence of CSDH after operation in UIAs patients and RIAs patients was compared.The risk factors of CSDH after UIAs and RIAs patients were analyzed by multivariate Logistic regression model.Results The incidence of CSDH in UIAs and RIAs patients (10.78％ vs 3.13％,x2 =10.487,P =0.001) and the reoperation rate after CSDH (3.92％ vs 0.78％;x2 =5.599,P =0.018) were all statistically different,all of which showed that the patients with UIAs were higher than those of the patients with RIAs.Brain atrophy of grade 3-4 (OR =1.978,95％ CI:1.939-2.030,P ＜ 0.001),subdural effusion CT value ≥40 (OR =3.394,95％ CI:2.908-3.867,P ＜ 0.001) and subdural effusion (OR =2.872,95％ CI:2.648-3.019,P ＜0.001 grade) of Ⅰ B are independent risk factors of CSDH in patients with UIAs after aneurysm clipping (P ＜0.05).Subdural effusion CT value ≥ 40 (OR =3.442,95％ CI:2.918-3.8769,P ＜ 0.001) and grade Ⅰ B subdural effusion (OR =2.329,95％ CI:2.011-2.564,P ＜ 0.001) are independent risk factors for CSDH in patients with RIAs after aneurysm clipping (P ＜0.05).Conclusions The incidence of CSDH after aneurysm clipping in UIAs patients was significantly higher than that of RIAs patients.The risk factors for CSDH in the two groups were not the same.
