Wake-up stroke in a young woman with rotational vertebral artery occlusion due to far-lateral cervical disc herniation.
Wake-up stroke is most likely to be caused by small-vessel disease, and is related to snoring. The authors present a rare case of far-lateral cervical disc herniation with neck rotation, resulting in wake-up stroke in a young woman. The patient, a 31-year-old woman, was admitted to the hospital because of dysarthria and confusion when she awoke in the morning. Brain MRI showed acute infarction in the posterior fossa. Cerebral angiography showed thrombus in the distal top of the basilar artery and the bilateral posterior cerebral arteries. During angiography, the thrombus size decreased with heparinization. There was severe stenosis of the right vertebral artery (VA) at C5-6, and head rotation to the right resulted in complete occlusion of the right VA. Neck MRI showed far-lateral intervertebral disc herniation. Surgical decompression of the VA was performed via the anterior cervical approach. Histological examination showed a degenerative intervertebral disc. Postoperative angiography confirmed successful decompression of the VA.
