OBJECTIVES: The purpose of this study was to examine the safety and efficacy of target embolization of aneurysms associated with ruptured brain arteriovenous malformations (BAVMs). METHODS: Ruptured BAVM patients who underwent endovascular treatment at our institution from January 2011 to December 2015 were retrospectively reviewed. Patients were divided into aneurysm (AN) and nonaneurysm (non-AN) groups on the basis of the existence of BAVM-associated aneurysms or not. Demographics, angiographic characteristics, complications, and clinical outcomes were compared between 2 groups. Complication risk factors were analyzed for all objects. Patient outcomes were assessed with modified Rankin Scale (mRS). RESULTS: A total of 129 (male = 53) patients were included. In 31 (24.0%) patients, 33 aneurysms were observed, including 16 intranidal and 17 flow-related aneurysms. Of the 166 sessions of embolization performed, there were 13 (10.1% of patients, 7.8% per session) complications in all, including 2 hemorrhagic, 8 transient ischemic, and 3 permanent ischemic types. There was no statistical difference in terms of complication incidence rate between groups. A total of 12 patients (9.3% of patients, 3.3% per person-year) experienced postoperative hemorrhage during follow-up (mean = 3.4 years). The yearly postoperative hemorrhage incidence rate was 3.4% in the non-AN group and 2.0% in AN group. Excellent or good outcomes (mRS <= 2) were observed in 103 (91.2%) patients. Unfavorable outcomes (mRS >= 3) as a direct result of embolization remained in no patients. CONCLUSIONS: Target embolization of aneurysms associated with ruptured BAVMs could significantly decrease postoperative rehemorrhage without increasing complications.
