Repair of an arterial perforation of the internal carotid artery using Hemashield wrapping with aneurysm clip reinforcement: technical note.

Abstract

To review a technique used to repair a hole in the carotid artery encountered during the dissection and clipping of a giant paraclinoid aneurysm. The technique of repair involves wrapping the artery using a woven double velour material impregnated with bovine collagen (Hemashield; Meadox, Oakland, NJ) and securing the material around the carotid artery with an aneurysm clip. The intravascular pressure of the carotid artery provides the counterforce necessary to seal the hole. The carotid artery was slightly narrowed after the treatment. The patient made an excellent recovery from surgery. This technique provides an alternative means of repairing a defect in the walls of intracranial arteries.
