Flow diversion for the treatment of petrous internal carotid artery aneurysms

Abstract

Petrous internal carotid artery (ICA) aneurysms are rare and pose a unique management dilemma. They are most commonly fusiform. They are difficult to treat surgically and typically not amenable to selective aneurysmal obliteration. The advent of flow diverters, such as the Pipeline endovascular device, has offered a new approach to these historically challenging lesions. The unique utility of flow diversion in treatment of petrous ICA aneurysms is reviewed and discussed.

“…29,31 Because the carotid is encased in bone as it passes through the carotid canal in this region, endovascular treatment with flow diversion or coil embolization is preferred if treatment is required. 33 Traumatic pseudoaneurysm of the petrous carotid is very rare and has been documented after middle ear surgery. Both conservative and surgical treatments have demonstrated complete resolution.…”
