Peculiarities of the reaction of the lower limbs venous blood flow to the orthostatic test in men with arterial hypertension

Abstract

A comparative analysis of the dynamics of lower limb vein angioscopy parameters in case of orthostasis between male patients (age 30–50 years) with arterial hypertension (test group – 60 people) and normal arterial pressure (control group – 27 people) was made. Orthostatic sample in all examined patients was characterized by a reliable increase in the diameter and area of vein section at a decrease in blood flow rate. However, in patients with hypertension the increase in the area of vein section was significantly less than in the control group. In orthostasis, the drop in blood flow rate in the total femoral vein was lower in men with hypertension than in men in the control group. In the great saphenous vein, a larger decrease in blood flow velocity was recorded than in the control group. In hypertension, no increase in the number of refluxes was recorded in orthostasis. Thus, hypertension in men is characterized by altered reaction of venous blood flow to orthostasis in both deep and saphenous veins.
