Endovascular coil embolization for internal carotid artery pseudo-aneurysm after traumatic injury in a young adult: a case report

Abstract

Purpose: This article describes a case of internal carotid artery (ICA) pseudo-aneurysm in young adult after blunt trauma successfully treated with endovascular intervention.
Case presentation: A 19-year-old male had traumatic subarachnoid hemorrhage, intraventricular hemorrhage, and cerebral contusion caused by a traffic accident two years ago. An MRA showed a saccular aneurysm arising from the C4 portion of the left ICA, prompting consideration of the condition as a post-traumatic pseudo-aneurysm. Successful endovascular coil embolization of the pseudo-aneurysm was achieved without any complications.
Conclusion: An aneurysm after traumatic injury in a young adult should arouse suspicion that the condition is a pseudo-aneurysm. This case report suggests that this condition can be treated with endovascular coil embolization.
