The authors reported 2 patients with ischemic stroke who had a spasm of the subclavian artery-vertebral artery system caused by cervical ribs. Example 1, female, 20 years old. Due to rapid loss of consciousness lost on September 16, 1977 admission. In the same year after the delivery of the left upper extremity pain, weakness and no radial artery pulse. Check: the left radial artery pulse disappeared, the right force of 82 times / min. Blood pressure 115 / 70mmHg.

Left move with neurological paralysis, pupil light reaction disappeared, the right side of the central paralysis and hemiparesis. After hours of consciousness recovery. Cervical X-ray found on both sides of the cervical ribs, the right cervical rib almost vertical down, left cervical rib hypoplasia and stenosis. Aortic scoliosis angiography and left subclavian artery and branch angiography, after the discovery of left subclavian artery stenosis and expansion of the left exit of the left vertebral artery stenosis. October 11 left bevel muscle incision and found that the lateral left anterior scalene muscle fixed in the abnormal ribs, supraclavicular artery fusiform expansion, straight
