Abstract:
Objective To investigate the incidence of symptomatic cerebral vasospasm in patients with ruptured intracranial aneurysms after embolization and its correlative factors. Methods The clinical data of 78 patients with ruptured intracranial aneurysms after embolization, admitted to our hospital from May 2008 to January 2010, were retrospectively analyzed. The occurrence of symptomatic cerebral vasospasm was assessed and its influencing factors were analyzed. Results The embolization of these 78 patients was successful. Postoperative symptomatic cerebral vasospasm occurred in 20patients (25.6％). Significant differences in the incidence of cerebral vasospasm among patients of different Hunt-Hess grades, Fisher grades were noted (P＜0.05). Fourteen patients were back to normal and 3 had moderate disability after proper treatment,while the other 3 gave up treatment. Conclusion The occurrence of symptomatic cerebral vasospasm of patients with ruptured aneurysm atter embolization may be associated with the neurological damage degree and amount of bleeding. Lumbar drainage can positively reduce the incidence of cerebral vasospasm.
