[Traumatic dissection of bilateral vertebral arteries].

58-year-old male comatose patient following a motor vehicle accident with a history of coronary bypass surgery 5 years ago has been presented. The patient was awake after the accident and he became comatose 30 minutes after the accident. The early diagnostic investigations showed no responsible cranial or spinal lesion. At the 2nd day of the accident, diffusion weighted magnetic resonance scans, magnetic resonance arteriography and digital subtraction arteriography revealed bilateral vertebral artery dissection at the second part of the vertebral arteries. Clinical, radiological features and treatment options of the vertebral artery dissection has been discussed with the ertinent literature.
