| Popis: | Chronic venous insufficiency (CVI) is a common disorder condition worldwide. Compression therapy is the mainstay of prophylaxis and treatment of CVI in practice. The aim of this study is to investigate effects of the designed knee-high open-toe compression stocking (OTCS) on venous cross-sectional areas and flow velocities of the superficial and deep venous systems of the lower extremities. The results indicated that the designed OTCS (23 mmHg at ankle on average in a standard degressive pressure gradient from the distal to the proximal) can effectively squeeze limb tissues and generate different influences on the studied cross-sectional areas and flow velocities of the superficial and deep venous system. In general, the cross-sectional areas reduced by approximate 13%–16% along the tested superficial veins (Great Saphenous Vein and Small Saphenous Vein) in both healthy subjects (Group 1) and CVI patients (Group 2). The decreased venous cross-sections may squeeze superficial venous blood to deep venous system via perforator veins, leading to increased venous cross-sectional areas by 7% in Popliteal Vein vein in Group 1 (healthy subjects) and increased flow velocity of deep veins by approximate 6.5% and 19.6% in Group 1 and 2, respectively. These finding suggest that the designed new OTCS would improve venous haemodynamics of the lower limbs in dynamic daily use, especially for deep venous system of the CVI suffers. |
