In this report, we describe the use of the Comaneci device to support microcatheterization in a small branch arising from a parent artery during embolization. In 2 cases, arteriovenous malformations presented with intracranial hemorrhage. A microcatheter was navigated into a small feeder while the Comaneci device was deployed just distal to the feeder with an acute angle from the parent artery. Our technical note represents an alternative option of catheterization in cases with difficult access to small feeders originating from higher flow arteries at a sharp angle while maintaining continuous flow in the parent artery.
