Abstract
Twelve cases of cerebral arteriovenous malformation (AVM) were managed with intravascular surgery preoperatively, in order to facilitate surgical removal. In 10 of these cases, preoperative balloon occlusion of the feeding arteries was performed by means of detachable balloon catheter. In the rest of the cases, preoperative embolization of the AVM was performed by EVAL through Tracker infusion catheter. There was no complication after preoperative balloon occlusion and one transient aphasia related to preoperative embolization. None of the cases developed normal perfusion pressure breakthrough. Preoperative balloon occlusion was thought to be safe and to decrease the difficulty in surgical resection of the AVM. Preoperative embolization seems to be more effective than balloon occlusion; however, it should be performed carefully without causing complications.
