Abstract
The study based on ultrasound angioscanning examination of the venous bed in early postoperative period in 74 patients with fractures of bone diaphysis of lower extremity after internal osteosynthesis. Pathology of deep venous bed of the lower extremity was found in 51.4%, thrombosis - 24.3% of cases. Half of the revealed proximal thrombi of the deep venous bed were floating, thus, creating highest risks of embolism. It was found out that in cases of femur and tibia diaphysis fractures changes of anterograde blood flow are most persistent and relevant in muscular-venous sinuses of the lower leg. Thrombosis of the femoral-popliteal segment of the venous bed leads to anatomo-hemodynamic changes in the system of deep veins of the injured leg and to increase of blood volume in superficial veins. Fractures of the bones of the lower extremity lead to changes in the system of deep veins of noninjured extremity.
