An extracranial carotid artery pseudoaneurysm is a rare condition that is caused by various types of arteritis, trauma and infectious causes. Generally, a pseudoaneurysm may be difficult to treat surgically when dissecting the paraaneurysmal fibrotic dense inflammatory tissues. The surgical management of a peudoaneurysm of the carotid artery involves a risk of nerve and arterial injury. This paper reports the repair of a carotid artery pseudoaneurysm after the proximal and distal control of the internal carotid artery using a Pruitt-Inahara shunt (P-I shunt) and the distal control of the external carotid artery using a small sized occlusion balloon catheter.
