Repair of an arterial perforation of the internal carotid artery using hemashield wrapping with aneurysm clip reinforcement: Technical note

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