During the past decade it has been demonstrated that the primary arterial occlusion in many patients with cerebral vascular insufficiency was localized to the cervical portion of the cerebral vessels. Improvements in techniques of vascular surgery have made it possible in many to restore the circulation to relatively normal limits. The most common cause of occlusion is arteriosclerosis. More frequent than previously suspected is partial or complete occlusion due to tortuosity and buckling of the vessels.
Riser et al. in 1951 reported a case of carotid artery insufficiency due to coiling of the artery in the neck.6 Symptoms were relieved by straightening of the segment and attachment of the artery to the underside of the sternomastoid muscle. Gass in 1958 reported 7 cases and correction of 1 unsuccessfully by resection and an end-to-end anastomosis.3 Smathers and Smathers resected a severely coiled carotid artery and performed an end-to-end anastomosis
