THE CONDITION OF BRAIN HEMO DYNAMICS AT PATIENTS WITH OBLITERATING ATHEROSCLEROSIS OF ARTERIES OF THE BOTTOM EXTREMITIES

Abstract

Purpose: Examine the state of cerebral hemodynamics in patients with obliterative atherosclerosis of the lower extremities.
Materials and methods: Patients were divided into 3 groups depending on the degree of chronic limb ischemia. In one group (67 people) included patients with B II degree of ischemia. The 2nd group (36 patients) included patients with grade III ischemia. In the 3rd group entered 21 patients with a decompensation of collateral blood circulation into the extremities, being accompanied the expressed pain syndrome (the IV degree of ischemia). State of the blood flow was assessed by Doppler ultrasound data on the levels of the extracranial and intracranial arteries brachycephalic departments.
Results: In patients with decompensation of collateral circulation of the lower limbs (group 3), a significant decrease in the rate of blood flow in the internal carotid arteries in comparison with the indicators of all other groups .
Summary: Severe chronic ischemia of the lower limbs should be seen not only as a negative factor for the lower extremities, but also as a factor in reducing the risk of cerebral perfusion and significant deterioration of autoregulatory reserve of cerebral hemodynamics.
