Carotid pseudoaneurysms are rare occurrences. They often result from trauma, but can also present following carotid endarterectomy. Treating such pseudoaneurysms can be difficult due to previous surgery and limited access to the high internal carotid artery. A case involving a postendarterectomy carotid pseudoaneurysm treated via a femoral approach with a covered stent using endoluminal techniques is presented.

The management of patients with head and neck cancer can be complicated by massive carotid artery hemorrhage, often requiring ligation owing to the emergent conditions and scarring from previous surgery and radiation. A case of emergent endovascular management of carotid artery hemorrhage in a patient treated for pharyngeal carcinoma is described. Hemorrhage was controlled, but on follow-up the patient developed a carotid-cutaneous fistula with exposure of the coils. Further management required the use of autogenous vein to replace the involved vessels. This case demonstrates that endovascular control of carotid hemorrhage can be successful, but close follow-up is necessary to identify potential subsequent complications.
