title: [A case of bow hunter's stroke].
abstract: A case of vertebrobasilar insufficiency with vertigo and horizontal nystagmus induced by neck rotation is reported. This patient's angiography demonstrated obstruction of left vertebral artery at the Cl-2 level on right rotation of the head. Surgical decompression of the vertebral artery by partial transversectomy of the atlas vertebra in this case relieved the symptoms, and postoperative angiography demonstrated the disappearance of the vertebral artery occlusion at the neck rotation. The pathogenesis and treatment of vertebral artery occlusion at Cl-2 level are discussed.
