Summary. Despite reports of plication with inferior vena cava thrombosis, the venous hemodynamics before and after hardware cavaplication has been not evaluated. The aim of research. Estimate the changes of the venous blood flow indices after complication in patients with vena cava inferior thrombosis. Materials and methods. Quantitative assessment of venous blood flow was performed in 34 patients with inferior vena cava thrombosis before and after incomplete hardware cavaplication. Cavaplication was performed in 11 (32.4 %) patients with non-tumor and in 23 (67.6 %) patients with tumors of the vena cava inferior. For selecting the site of cavaplication, the infrarenal branch of the vena cava inferior directly below the renal veins was prevailed – in 29 (85.3 %) patients, the plication of vena cava inferior lower or higher hepatic veins in 4 (11.8 %) and 1 (2.9 %) patients were performed respectively. Results. Increases of following indices of central and regional hemodynamics after hardware cavaplication were observed, in particular, volume (by 56.5 %) and the linear rate of blood flow (by 40.4 %), minute volume of blood flow (by 16.2 %), cardiac index (by 8.8 %), systolic volume (by 6 %), end-systolic volume index (by 4.5 %), end-diastolic volume index (by 3.9 %) and ejection fraction (by 2.1 %). Instead, the pressure in the inferior vena cava (by 18.2 %) and stroke volume (by 8.9 %) decreased, which, however, was also considered as a positive result of thrombectomy from the vena cava inferior and hardware cavaplication. Conclusions. Within a year after inferior vena plication, indicators of central and peripheral hemodynamics were within the physiological norm and collateral pathways during radioisotope phleboscintigraphy weren`t determined. At the same time, the lumen of the vena cava inferior was completely restored, after 12-18 months, in all cases after plication.

Our aim was to measure the venous blood flow velocity (VBFV) in case of hemiparetic patients, after passive and active thromboembolic methods, as well as the consensual effect in the hemiparetic limb following the active venous exercises in the healthy limb. We examined 215 patients, with the median age of 58.0 (55.0-63.0) years. The VBFV was measured with a HADECO BIDOP ES-100 V II type Doppler ultrasound device, using an 8 MHz head, on the femoral vein at the level of the hip joint. For statistical analysis, SPSS version 22 was used. After passive movement, on the hemiparetic side, compared to the value in resting state, the VBFV significantly (12.6; 11.6-13.5 cm/s; P < .001) increased. Following active venous exercises performed on the healthy side, the VBFV significantly (18.0; 15.6-19.6 cm/s; P < .001) increased compared to the value in resting state. Following the active venous exercises performed on the healthy side, the VBFV measured on the hemiparetic side (consensual effect) was significantly (15.1 [14.1-16.5] cm/s; P < .001) higher than the value on the hemiparetic side in resting state. Active and passive mechanical thromboprophylaxis methods can be effective. Movements of the healthy limb significantly increase the VBFV in the inactive limb, and patients can perform it themselves several times a day.

Objectives: To measure the effect of graduated compression stocking (GCS) length and body position on peak femoral venous blood flow velocity (PVV) and vessel diameter (VD). Methods: Twenty healthy adult volunteers had PVV and VD measured, using colour Doppler ultrasound, at baseline in three body positions. Knee- or thigh-length GCS were assigned randomly.Arandom sequence of the three positions was used to measure PVV and VD. The procedure was repeated, after a two-hour washout period, using the other length GCS. Results: There was no significant difference in the mean change of PVV ( P =0.74) or VD ( P =0.54) measurements from the baseline between thigh- and knee-length GCS. However, significant mean changes in PVV ( P =0.02) and VD ( P <0.001) measurements were observed for the three body positions, after adjusting for baseline values. Conclusions: In healthy volunteers, thigh- and knee-length GCS do not have an effect on PVV or VD, and body position affects PVV significantly, with or without GCS.
