Endovascular treatment for pseudoaneurysm after carotid blowout syndrome

Abstract

Background Pseudoaneurysms of the carotid artery are rare and can be both a cause and consequence of carotid blowout syndrome (CBS) in patients with head and neck cancer. Surgical or endovascular treatment approaches may be useful for managing this condition. Case Report A 55-year-old man presented with a pulsatile mass surrounding the carotid bifurcation in the neck. He reported a history of CBS that occurred as a surgical complication while removing a benign neck cyst. Additionally, he reported a history of laryngeal cancer that underwent complete remission after surgery and radiotherapy. The mass was diagnosed as a pseudoaneurysm. Surgical treatment proved challenging owing to the patient’s history of neck surgery and radiotherapy; therefore, stent-graft deployment was performed and the absence of pulsations was checked through the neck mass. Conclusion Endovascular treatment may be a useful therapeutic strategy in cases of post-CBS pseudoaneurysm in patients undergoing surgery and/or radiotherapy for head and neck cancer.
