Post-traumatic Pseudoaneurysm of a Branch of Facial Artery

Abstract

Pseudoaneurysm which is also known as a false aneurysm is caused by extravasation of blood from the injured vessel wall which is contained by the surrounding soft tissue. It does not contain any layer of the vessel wall and can expand as more and more blood collects. We are reporting a case of an 18-year-old Indian gentleman who presented with complaint of left neck swelling after being involved in a motor vehicle accident. Examination showed a softly pulsating swelling at the angle of the left mandible. CT angiogram revealed a pseudoaneurysm of a branch of the left facial artery. The pseudoaneurysm was embolized by using histoacryl glue. Pseudoaneurysm should be considered as a differential diagnosis in patients with a pulsatile mass after trauma.

Pseudoaneurisma de la arteria facial como complicación de un absceso parafaríngeo. Presentación de un caso y revisión de la literatura.

“…( 2009) ilustra el carácter poco usual de estas, donde se reportaron nueve casos en veinticinco años 3 . En este territorio, se han descrito pseudoaneurismas de las arterias temporal superficial, maxilar interna, lingual y facial, siendo la arteria temporal superficial la de mayor incidencia 12 . A nivel de la arteria facial los pseudoaneurismas son raros, debido a su pequeño calibre, y la mayor parte de los casos descritos son debidos a traumatismos directos o cirugía mandibular 13 .…”
