Introduction: Bow hunter's syndrome is a unique clinical entity caused by mechanical occlusion of the vertebral artery on head rotation. Although it is usually treated by direct surgical intervention, we report successful treatment using endovascular stent placement for contralateral vertebral artery stenosis. Case Description: A 56-year-old man presented with repeated vertigo and loss of consciousness caused by turning his head to the left. Right vertebral angiogram showed no abnormalities with the head in the neutral position. However, with the head rotated 60 to the left, the right vertebral artery was completely occluded at the C1-2 level. A three-dimensional angiogram with bone window clearly demonstrated vertebral artery compression at the C1-2 level by the bony structure. The left subclavian angiogram revealed severe stenosis at the origin of the left vertebral artery. Left vertebral artery angioplasty followed by stent placement was successfully performed under local anesthesia. The patient showed an uneventful postoperative course and his preoperative symptoms disappeared. At 6 months postoperatively, a left subclavian angiogram showed good patency of the stented left vertebral artery and the patient showed no recurrent symptoms. Conclusion: Vertebral artery stenting is a useful and less invasive option in the treatment of bow hunter's syndrome in the setting of contralateral vertebral artery stenosis.
