Delayed diagnosis of blunt carotid trauma in a seat belt syndrome with associated abdominal wall injury A case report.

The aim of this case report is to be aware of occult carotid lesions in thoracic- abdominal trauma because, carotid artery injury consequent to blunt trauma is rare, affecting less than 1% of patients as reported in literature. A 45-years-old female, involved in a traffic accident, arrived to Emergency Room hemodynamically stable, with a Glasgow Coma Scale of 15, complaining abdominal pain, without any neurological signs. She underwent Computed Tomography (CT) scan that showed a complete disruption of left abdominal wall muscles, associated with massive bowel loops herniation. No free air nor other visceral injuries were found. The radiological brain evaluation was negative for neurological injuries. Considering the nature of the trauma, an explorative laparotomy was performed. During the fifth postoperative day, the patient presented neurological side signs with right facial-brachial-crural hemiparesis and expressive aphasia. Head and neck CT scan revealed a lesion of the left common carotid artery with distal embolization of the internal carotid. A left-carotid-axis revascularization procedure and a surgical endarterectomy were immediately performed. Patient was discharged after 20 days without neurological consequences. Physicians should be aware of neck vascular injuries when evaluating patients with multiple trauma, even in neurological asymptomatic patients without seatbelt abrasions of the neck skin.
