Radionuclide study of the state of the regional lymphatic system in patients with deep vein thrombophlebitis of the lower extremity

Resume: Thrombosis thrombophlebitis of superficial veins is a pathological condition in which thrombotic masses are formed in the superficial veins with the development of a concomitant inflammatory reaction of the skin and subcutaneous tissue. The main method of instrumental diagnostics of TPPV is ultrasonic duplex angioscanning. The method makes it possible to assess the condition of the walls and lumen of veins, the presence of thrombotic masses in them, the nature of the thrombus (occlusive, parietal, floating), its distal and proximal borders, the patency of deep and perforating veins. To date, there are no reliable ultrasound criteria for assessing the duration of the thrombotic process. The standard research protocol should include scanning the superficial and deep veins of both the affected and contralateral limbs to exclude simultaneous thrombosis. The deep venous bed is examined along the entire length, from the distal parts of the leg to the level of the inguinal ligament, and if intestinal gas does not obstruct, then the vessels of the ileocaval segment are examined. During ultrasound examination, it is required to accurately indicate the proximal border of the lesion, to note the presence / absence of varicose or PTB.
