ObjectivePenetrating carotid trauma in a hemodynamically stable patient invariably presents with a pseudoaneurysm on initial imaging. Although extremely rare, delayed pseudoaneurysm formation has been reported. The purpose of this paper is to define this rare entity and propose a diagnostic and treatment plan.MethodsWe present a case of delayed presentation of carotid pseudoaneurysm following penetrating neck trauma. A systematic review of the literature was performed.ResultsA 21-year-old male presents to the trauma center after sustaining a gunshot wound to the left upper back resulting in a zone 2 hematoma and pneumothorax. Bullet fragment artifact interfered with computed tomography. Carotid angiogram was normal. The patient was discharged after 3 days. He returned to the Emergency Department 3 months later with a painful pulsatile hematoma. Computed tomography angiogram revealed a 6-cm pseudoaneurysm arising from the proximal left internal carotid artery (ICA). A left common carotid artery (CCA) to ICA bypass with reversed great saphenous vein was performed. The patient's post-operative course was uneventful, neurologic deficits improved, and he was discharged.ConclusionDelayed presentation of traumatic pseudoaneurysms has been reported, although usually these cases are iatrogenic access complications in extremities. While endovascular therapies are first line for zone 1 and 3 vascular injuries, management of zone 2 injuries is still controversial. This patient was treated with a bypass due to the need to evacuate the hematoma that was exerting a mass effect in the neck.
