摘要
FIELD: medicine.;SUBSTANCE: invention refers to medicine, namely to ultrasonic diagnostics in orthopaedics and traumatology. An early postoperative period involves finding echo-producing structures in a lumen of deep tibial veins according to duplex compression angioscanning. The grey-scale real-time B-mode duplex angioscanning procedure is performed on the first postoperative day from an approach to a popliteal vein. The compression exposure is manual and covers a distal segment of the ankle. If observing a homogenous lumen of the popliteal vein that corresponds to norm, the absence of thrombotic structures in the popliteal vein directly and the absence of the thrombosis process in the distal segments of the deep tibial veins are diagnosed. Small, different-calibre echo-producing structures flowing with blood, having a maximum size up to 0.8-1.0 mm in the lumen of the popliteal vein, and accelerating in the proximal direction with the manual decompression of the distal segment of the ankle enable diagnosing the initial stage of thrombosis in the distal segments of the deep tibial veins.;EFFECT: technique enables the early postoperative diagnostics of the thrombosis in the distal segments of the deep tibial veins by detecting the marker signs of this process.;7 dwg, 3 ex
