Surgical management of cerebral arteriovenous malformations with intraoperative digital subtraction angiography

Complete excision of cerebral arteriovenous malformations (AVMs) is requisi te to improving the outcome of patients with AVMs. Five patients with a sma ll or medium cerebral AVM underwent surgery with an intraoperative digital subtraction angiography (DSA) unit. There were no residual AVMs and no comp lications in the examination of intraoperative DSA. The findings of postope rative angiography were consistent with those of intraoperative DSA, Intrao perative DSA provided the benefits of not only identification of a feeding artery, but also recognition of the complete excision during surgery.
