Maxillofacial Gunshot Wound & Delayed Psuedoaneurysm: Recognition & Endovascular Intervention

Pseudoaneurysms of the extracranial head and neck vasculature are rarely encountered. However, they bring significant risks when present. There is an adequate buffer of soft tissue in the maxillofacial region reducing the incidence. Most trauma to the external carotid artery and its branches will predominately cause complete transection rather than partial laceration. The process of a pseudoaneurysm formation is a partial vessel wall breach resulting in leakage of arterial blood into surrounding tissues.
