Ruptured presentation of superficial temporal artery pseudoaneurysm treated with anastomotic repair: Case report

Abstract

Superficial temporal artery (STA) pseudoaneurysm is a very rare occurrence that usually presents as a pulsatile mass along the STA distribution following trauma or an iatrogenic cause. We report a case of STA pseudoaneurysm that developed in a 32 year old male following blunt trauma. Unfortunately, the pseudoaneurysm was missed and led to multiple hospital presentations that culminated in an acute bleeding episode. Surgical resection of the pseudoaneurysm was performed and the STA was reconstructed with an STA-STA anastomosis. To our knowledge, this is the second reported case of an STA pseudoaneurysm treated with an STA-STA anastomosis. This case report aims to bring awareness. Although extremely rare, the importance of treating the presence of a pulsatile mass along the STA distribution following a history of trauma or recent cranial surgery with a high level of suspicion is imperative.
