False Aneurysms Complicating Internal Carotid Artery Dissection

Pseudoaneurysm formation is a rare but dangerous complication of carotid artery dissection. It can result from trauma, spontaneous artery dissection, or iatrogenic causes. Presence of symptoms and ineffective medical therapy are one of the indications for invasive treatment. We present the case of 3 symptomatic patients with dissecting pseudoaneurysms—2 traumatic and 1 spontaneous. They were treated with 3 different endovascular procedures: the use of covered stentgraft, trans-stent coil embolization, and carotid stenting. After invasive and dual antiplatelet therapy, complete resolution of symptoms was achieved in all patients.
