Traumatic bilateral carotid dissection.

Traumatic dissection of the carotid artery is an infrequent but serious complication of blunt cranial-cervical injury. The typical patient presents with deficits attributable to cerebral ischemia in the distribution of the affected vascular supply. Key considerations in the clinical picture are a delay in symptom presentation, normal initial computed tomography scans, and potential for concomitant cerebral or visceral injury. Because the initial clinical and diagnostic picture may be normal, it is crucial for emergency physicians to aggressively search for this injury in the presence of blunt cranial trauma. We present an unusual case of bilateral high extracranial carotid dissection secondary to blunt trauma. The pathophysiology of carotid artery trauma, treatment options, and key acute care issues are discussed.
