Emergent Surgical Treatment Of Intracranial Aneurysms

Objective To analyse the results of emergent micro-neurosurgical treatment for intracranial aneurysms.Methods Ten cases with intracranial aneurysms undergoing emergent surgical treatment were retrospectively reviewed. And a follow-up study was performed.Results The average interval between the onset of symptoms and admission to hospital is 8.1 hours; Between admission and the emergent surgical treatment is 18 hours; so mean time from the onset to surgery is 26.1 hours. All 10 patients' intracranial aneurysms did not ruptured during operation. Postoperatively two cases (20%) were complicated with cerebral vasospasm, one(10%) of which had ischemic symptoms; one case (10%) with communicating hydrocephalus after one month; one case (10%) with suspected rebleeding of untreated aneurysm who was diagnosed as multiple aneurysms and died suddenly. The complication rate was significantly lower than patients undergoing late surgery. The prognosis was evaluated by Glasgow outcome scoring (GOS) system. Patients scoring 4 points and 5 points account for 80%. The prognosis was better than that of patients with late surgery.Conclusion Aneurysmal subarachnoid hemorrhage is a common neurosurgical emergency. Emergent surgical treatment guided by cerebrovascular CTA (computed tomographic angiography) can significantly reduce the risk of complications such as rebleeding and cerebral vasospasm, as well as the morbidity and death rate, and improve the prognosis of patients subsequently.
