Aneurysmal subarachnoid hemorrhage in patients treatment using the Gugliemi detachable coil system(report of 14 cases)

Objective:To investigate the efficiency of Gugliemi detachable coil(GDC) in the treatment of intracranial aneurysms with subarachnoid hemorrhage.Methods:Between July 2000 and October 2003, 14 patients with 16 intracranial aneurysms were embolized using Gugliemi detachable coils (GDC).The clinical notes and imaging were reviewed retrospectively.Hunt-Hess grade, Ⅰ 4cases, Ⅱ 7cases, Ⅲ 2cases, Ⅳ 1cases.Lumbar subarachnoid drainage was instituted postoperatively. Final angiographic follow-up time ranged in 6 months in 7 cases.Results:Aneurysms were located in the internal carotid-posterior communicating artery (n=5), anterior communicating artery (n=3),the basilar bifurcation (n=3) and the cavernous vertebral artery (n=3).Among 16 aneurysms,total occlusion in 15 cases, subtotal occlusion in 1 case.Overall,improvement or resolution of CN symptoms after treatment was noted in 3 patients.Ptosis was the initial symptom to show improvement in 4 cases, while EOM dysfunction responded least favourably in 7 cases. No aneurysmal rupture was observed during treatment.Conclusion:The results of short-term follow-up suggested that embolization of intracranial aneurysms with GDCs be microtraumatic, safe,effective,and reliable.Although the number of patients in this study is small, there is evidence that the angiographic outcome is better for intracranial aneurysms.Our results are comparable to other published series.
