Timing Of Surgery And Prognosis For Poor Grade Intracranial Aneurysms

Objective To discuss the microsurgery clinical therapeutic effect in different surgery time for poor grade intracranial aneurysms.Methods A retrospective analysis of 33 patients with poor grade intracranial aneurysms from 2003.1 to 2004.12.Results The ratio of good recovery was 33.3% in early surgery time with Hunt—Hess grade IV intracranial aneurysms while 38.5% in delay surgery time; The ratio of death was 33.3% in early time while 30.1 % in delay time; the hospital day was 14.4±9.4 in early time while 23.5±10.2 in delay time (P<0.05). The ratio of good recovery was 33.3% in early surgery time with Hunt—Hess grade V intracranial aneurysms while 12.5% in delay surgery time; The ratio of death was 66.7% in early time while 75.0% in delay time; the hospital day was 10.3±12.7 in early time while 24.3±19.1 in delay time, but every has no notable statistics significance set.Conclusion There is no big difference between the prognosis and the timing of surgery on Hunt—Hess grade IV intracranial aneurysms. But the hospital day of early time is shorter than that of delay time. The mortality/Disability rate is relatively high because of the difficulty in operation on Hunt—Hess grade V intracranial aneurysms, For Hunt-Hessgrade V operation should be postponed to 2 weeks later. CTA may be the first-choice for intracranial aneurysm in the diagnosis after SAH.
