Abstract

Traumatic pseudoaneurysm of the superficial temporal artery (STA) is an uncommon lesion and resection of the lesion is the treatment of choice. Three patients with traumatic pseudoaneurysm of the STA treated with only manual compression of the lesions were examined for this study. We report on an effective and safe minimally invasive technique for treatment of traumatic pseudoaneurysm of the STA.

  Fig. 1 (A) The lateral view of the selective external carotid artery angiography shows a pseudoaneurysm (arrow) with an arteriovenous malformation (AVM) (arrow heads). (B) The AVM was resected surgically. Manual compression was performed in just the proximal portion of the neck of the pseudoaneurysm. On the follow-up angiography five days after surgery with manual compression of the feeding artery, the AVM nidus and pseudoaneurysm had disappeared (arrow). (C) The gross finding showed a well-demarcated gray, rubbery mass (1.0 g, 1.5 × 1.2 cm). On section, the cut surface showed a cystic lesion filled with a dark-brown blood clot.

  Fig. 2 (A) A 1 × 1.5 cm pulsatile mass was visible on the right parietal region. (B) Doppler sonography showed swirling arterial blood-flow in the pulsatile mass. (C) Pre compression-treatment three-dimensional computed tomographic (3-D CT) angiogram shows a pseudoaneurysm with flow to the underlying artery. (D) After manual compression, the pseudoaneurysm was filled with thrombus, and there was no arterial blood flow in the lesion. (E) Post compression-treatment 3-D CT angiogram shows obliteration of the pseudoaneurysm.
