Spinal manifestations of vertebral artery dissection.

Among 111 patients with vertebral artery dissection (VAD), two presented with spinal manifestations: one with a C5-C6 radiculopathy and the other with a cervical myelopathy. Of 13 previously reported cases of spinal manifestations of VAD (mean age 37 years), ischemic cervical myelopathy was noted in seven; cervical radiculopathy, often at C5-C6 and primarily motor, in five; and hemorrhagic complications in one, with chest pain being part of the presentation.
