Abstract
The authors report their experience using electrolytically detachable coils for the treatment of ruptured posterior circulation aneurysms. Twenty- six patients with 28 posterior circulation aneurysms were treated. All patients were referred for endovascular treatment by experienced vascular neurosurgeons. Patients underwent follow-up angiography immediately after treatment, 1 to 6 weeks posttreatment, and 6 months posttreatment. Six-month follow-up angiograms obtained in 19 patients with 20 aneurysms demonstrated that lB (90%) of the 20 aneurysms were 99 to 109% occluded, one aneurysm (5%) was approximately 90% occluded, and one aneurysm (5%) was approximately 75% occluded. The patient with the aneurysm that was approximately 75% occluded needed additional treatment, consisting of parent artery balloon occlusion, and was considered a treatment failure (3.8% of patients). There was one treatment-associated mortality (3.8%) but no treatment-associated serious neurological or nonneurological morbidity in the patient group. There was no recurrent aneurysm rapture during treatment or during the mean 27-month follow-up period. Endovascular treatment of ruptured posterior circulation aneurysms with electrolytically detachable coils can be accomplished with low morbidity and mortality rates. The primary goal of treatment-preventing recurrent aneurysm-can be achieved over the short term. Endovascular coil occlusion will play an important role in the treatment of ruptured posterior circulation aneurysms, particularly if long-term efficacy in preventing recurrent aneurysm hemorrhage can be documented.
