Abstract:
Objective To compare and analyze the occurrence of delayed cerebral ischemia(DCI)after coiling and clipping of intracranial aneurysms, and explore the risk factors of DCI. Methods A total of 236 patients with aneurysms diagnosed by CT angiography (CTA) or digital subtraction angiography (DSA) in Department of Neurosurgery, Tianjin Medical University General Hospital were enrolled in this study from March 2011 to May 2014. Patients were divided into clipping group(n=135) and coiling group(n=101). The clinical characteristics were compared between two groups, including gender, age, medical history, GCS score, Hunt-Hess grade, Fisher grade, WFNS grade, aneurysm location, prognosis and incidence of DCI. Risk factors for DCI were investigated by Logistic regression analysis. Results DCI was occurred in 36 patients (26.7%) underwent clipping operation while in 11 patients (10.9%) underwent coiling operation. The incidence was significantly higher in clipping group compared with that of coiling group (P <0.01). The patients were followed up for 6 months. The poor prognosis rates were 17.0%and 25.7%in clipping group and coiling group, respectively (P>0.01). The overall mortality was 11.0%, the former had a lower mortality rate (5.9% vs. 17.8%, P <0.01). According to Logistic regression analysis, Fisher Grade 3-4, postoperative pulmonary infection and surgical procedure were independent risk factors for DCI (P<0.01). Conclusion DCI is one of the most significant factors for high fatality and morbidity of postoperative aneurysm patients. There is a low occurrence of DCI after coiling compared with that of clipping. If we pay more attention to risk factors associated with the DCI, it will improve the prognosis of postoperative aneurysm patients greatly.
