Mycotic aneurysm of the internal carotid artery--a case report.

Extracranial internal carotid artery (ICA) mycotic aneurysms are rare entities that may result in significant neurologic morbidity and mortality. Several operative techniques have been described in the literature for the management of this difficult condition. This case report describes a contained ruptured mycotic aneurysm of the extracranial ICA associated with Proteus mirabilis infection successfully treated by an end-to-end spatulated interposition saphenous vein graft.
