[Diagnosis and management of an intraoperative vertebral artery injury]

A patient with cervical myelopathy caused by marked degenerative alterations of the cervical spinal column at the level of cervical vertebrae 3/4 and relative spinal canal stenosis in the area of cervical vertebrae 5-7 was treated in the department of neurosurgery because of progressive myatrophy and paresis of muscles innervated from cervical nerves 5-7. The operation was performed with vertebrectomy of cervical vertebra 6, implantation of a Harms titanium cage with autograft and a plate and spongy bone screw fixation system. There exists an unusual--and not often publicized--complication during this surgical procedure in the area of the cervical spine, namely penetrating injury of the vertebral artery caused by the treatment with a plate and spongy bone screw fixation system. We describe such an injury of the left vertebral artery. The vertebral artery was intraoperatively embolized using mechanical embolization coils.
