Pseudoaneurysms represent a potentially fatal complication of trauma. They are readily identified by use of computed tomography and can be treated successfully by ultrasound-guided techniques or selective radiological procedures. Several therapeutic options exist and a multidisciplinary approach with interventional radiology can frequently obviate the need for surgical intervention.

Lateral Thoracic Artery Pseudoaneurysm as a Result of Penetrating Chest Trauma

Abstract
Pseudoaneurysms are potentially fatal complications of vascular trauma; however, they are rarely seen as the sole complication of penetrating injury. We present a case of a pseudoaneurysm with an associated arteriovenous fistula of the left lateral thoracic artery as a result of direct trauma from a knife stab. The patient presented only with a painful, swollen left pectoralis muscle. Upon diagnosis, he was taken to the interventional radiology suite and treated successfully with fluoroscopic guided coil embolization. Cases such as these are infrequent and should encourage more aggressive use of contrast enhanced computed tomography imaging for soft tissue injury, as a missed traumatic pseudoaneurysm may result in life-threatening hemorrhage.
