Traumatic Pseudoaneurysm Arising From Proximal Facial Artery: A Case Report and Literature Review

Abstract

Pseudoaneurysms of facial artery usually arise from the distal part of the vessel. Only 4 cases were described in the literature involving the proximal part of facial artery. We present a case of a traumatic pseudoaneurysm involving the proximal part of facial artery. A 50-year-old man was referred to our department for a progressively growing submandibular mass. He was injured by a sharp object during a car crash 30 days ago. After 3 weeks, the patient noted the appearance of a subcutaneous mass in the left submandibular area. Physical examination revealed a freely movable, painful, and pulsatile swelling. Ultrasound and computerized tomography scan showed a nodular lesion in the left submandibular area in continuity with the facial artery. The diagnosis of pseudoaneurysm of facial artery was suspected. The patient was treated by surgery. The pseudoaneurysm was resected with ligation of the proximal and distal ends of the facial artery.
