THE LOCAL FIBROSIS OF CERVICAL INTERVERTEBRAL MUSCLES AND ITS RELATIONSHIP WITH DIAMETER AND BLOOD FLOW OF VERTEBRAL ARTERIES IN HEALTHY AND ILL PATIENTS WITH ARTERIAL HYPERTENSION

The study of relationship of local fibrosis of cervical intervertebral muscles and diameter and blood flow of vertebral arteries was carried out. The duplex ultrasound analysis of vertebral arteries was implemented. The sampling included 148 patients with arterial hypertension aged from 34 to 67 years and 282 healthy patients aged from 17 to 67 years. It is established that rate of narrow (less than 2.8 mm) vertebral arteries at one of two sides increases with age. This fact testifies that narrowness of vertebral arteries is not of constitutional but age-acquired character. It is also established that the rate of fibrosis dramatically increased with age and often had asymmetric character. The more fibrosis was manifested more often the narrowing of vertebral arteries was detected. The more was fibrosis more often at the affected side was detected the decrease of velocity of blood flow, volume blood flow and the increase of pulse index. The ill patients have evidence of asymmetry of fibrosis at the left and right side as compared with healthy patients. This condition was especially marked in patients with arterial hypertension and complaints about giddiness.
