Intraoperative Angiography during the Resection of Arteriovenous Malformations : A New Device Enabling the Lateral Projection of the Head and Details Describing its Use

Abstract

In most cases involving intraoperative angiography for the resection of arteriovenous malformations of the head, the lateral view is favored because of less overlapping of the arteries, with the patient's head fixed at a right angle to the floor, so that the central ray is perpendicular to the median sagittal plane and parallel to the floor. In this paper, the authors describe a new device that is fixed to Sugita's head frame for a lateral projection of the head and provide details of their technique for performing intraoperative angiography.
