Traumatic pseudoaneurysm of the superficial temporal artery: case report and review of the literature

An uncommon vascular swelling in a child: post traumatic pseudoaneurysm

“…Pseudo aneurysms develop due to complete or partial disruption of arterial intima from trauma induced necrosis of part of the arterial wall. 5,6 Blood extravasates from the injured artery with formation of a hematoma and a pseudo capsule around it. The hematoma capsule then expands and the clot reabsorbs resulting in a cavity leading to pseudo aneurysm formation.…”

“…The hematoma capsule then expands and the clot reabsorbs resulting in a cavity leading to pseudo aneurysm formation. 1,2,5,6 It usually presents as a slow growing, pulsatile mass in the temporal area. Other symptoms that may occur are headache, ear pain, facial palsy or hemorrhage.…”

“…4 Pseudo aneurysms of the STA are very rare (less than 1% of aneurysms), and usually occur after blunt head injury. 4,5 We report the case of a 10-year-old child, with a pseudo aneurysm of the STA secondary to trauma.…”

Pseudoaneurysm of the facial artery territory in an odontogenic infection setting

“…Although these vessels tend to be protected by soft tissues, the risk rises as they approach the superficial layers to cross bone structures. The superficial temporal artery, facial artery, and some branches of the internal maxillary artery are the most frequently affected [5][6][7]. Pseudoaneurysms can develop immediately after a traumatic event, but more usually show delayed occurrence after days, months, or even longer [7,8].…”

Pseudoaneurysm as a Post-Biopsy Complication

“…The hematoma may canalize and remain in persistent communication with the lumen of the artery. Most reported cases on the face occurred on the superficial temporal artery and its branches owing to its superficial course above the skull surface4. Suture ligation of the implicated artery is traditionally considered the treatment of choice5.…”
