Retrograde filling of the anterior choroidal artery: vertebral angiographic sign of obstruction in the carotid system.

abstract：:In small arteriovenous malformations (AVM) with large hematomas, surgery remains the main therapeutic option. However, intraoperative identification of the AVM, feeders, and draining veins could be difficult in the environment of substantial intracerebral blood. In those selected cases, we use navigated computed tomog...
