Clear Predominance

In vertebral arteries (v.a) most stenoses occur at their origins. Ultrasound studies with a 7,5 MHz sector duplex-probe are able to reveal the origins in 63 68% of the right, in 4362% of the left vertebral arteries (men omen), whereas the prevertebral and the intertrans versal parts C5/6C3/4 are visualized in 7090%. The mean cumulative lumen of both v.a. increases by age from 6,0 mm (age30) to 7,9 mm (age80) with a clear predominance of the left v.a. in 33%, of the right v.a. in 17%. Hypoplasia of one or both v.a. is present in 5,2%. In a sample of 1131 patients pathological findings occuredin 11% of the vertebral arteries (stenoses or occlusions, steal phenomena) and in 16% of the carotid arteries (stenoses 50% occlusions). In 42% of the cases with infarctions in the vertebro-basilar-supplied territories pathological duplex-findings were present, similary in 20% of infarctions in the carotid supplied territories, and in 15% of vertigo, but also in 62% of patients with peripheral vascular disease without, neurological signs or symptoms versus only in 3% of control-patients of similar age with out neurological or peripheral vascular disease.

Internal Carotid Arteries

Duplex carotid sonography was performed on 80 patients undergoing abdominal or peripheral vascular surgery for atherosclerotic disease. High-grade stenosis (over 50%) of one or both common or internal carotid arteries was present in 17 patients. In three of these patients ischemic cerebral infarcts developed in the territory of the most severely stenosed artery within 1 to 40 days after surgery. The other patients had no postoperative central nervous system complications. Duplex carotid sonography is indicated in patients prior to vascular surgery in order to identify the group at risk for the development of cerebrovascular accidents. Carotid endarterectomy prior to or at the time of surgery may prevent this complication.
