Abstract:
Objective To explore the clinical therapeutic efficacy and value of endovascular embolization treatment for Hunt-Hess poor-grade intracranial aneurysms. Methods Eighty-seven patients with Hunt-Hess grade Ⅳ - Ⅴ intracranial aneurysrns were treated with endovascular embolization from May 2001 to February 2010,77 patients were grade Ⅳ and 10 patients were grade Ⅴ. Outcomes were assessed by using the Glasgow outcome scale (GOS). Results Follow-up time was from 3 months to 9 years. The therapeutic efficacy was as following according to GOS: 25 patients were grade Ⅰ , 5 patients were grade Ⅱ , 9 patients were grade Ⅲ , 12 patients were grade Ⅳ ,and 36 patients were grade Ⅴ. There were 55.17%(48/87) favorable outcome rate and 28.74% (25/87) mortality rate in all patients. There were 61.70%(29/47) favorable outcome rate and 25.53%(12/47) mortality rate in early stage treatment patients (diseased within 3 d), otherwise there were 47.50% (19/40) favorable outcome rate and 32.50%(13/40) mortality rate in medium and late stage treatment patients (diseased 3 d or later). There were no statistically significance in favorable outcome rate and mortality rate between them (P > 0.05). All the patients were embolized successfully ,technical complications occurred in 8 patients, 10 patients were found angiographic evidence of vasospasm. Conclusions Endovascular embolization is an effective method for treating Hunt-Hess poorgrade intracranial aneurysms. Early stage treatment is a feasible option because it can improve prognosis by reducing rebleeding and vasospasm.
