A rare case report of trauma manifesting as multiple pseudoaneurysms of internal carotid artery and ipsilateral carotid cavernous fistula

Abstract

Carotid cavernous fistula is commonly caused by head trauma. Carotid cavernous fistula may be associated with intracavernous aneurysm of internal carotid artery, but occurrence of aneurysm at other site is rare. Management becomes complicated when carotid cavernous fistula is associated with aneurysm. Carotid cavernous fistula and aneurysm are managed by endovascular coiling with or without stenting. The management is more complicated if aneurysm is in cervical internal carotid artery along with carotid cavernous fistula. The decision to first obliterate what varies according to patient and doctor. We are reporting one of the rarest case of post-traumatic cervical internal carotid artery pseudo-aneurysms with carotid cavernous fistula following blunt head-neck injury and evidence based management strategies in such cases.
