    AbstractThe authors present the case of a 62-year-old man with a 4-month history of progressive left-sided C-5 radiculopathy and dizziness. Neuroimaging studies revealed a looped vertebral artery (VA) that had migrated into the widened left C4-5 intervertebral foramen. The patient underwent vascular reconstruction of the VA loop, in which there was minimal manipulation of the C-5 nerve root, via a left-sided anterolateral approach after a balloon occlusion test. Postoperatively the patient's symptoms improved immediately, and there were no signs of recurrence within the 2-year follow-up period. This excellent outcome supports the belief that a proper surgical reconstruction of the compressive, tortuous VA should be the therapeutic option of choice, which carries a lower risk of the nerve root injury and improves the hemodynamics in the posterior circulation.
