RESUMEN
Results of examination of 46 patients, suffering obliterating atherosclerosis of the lower extremities arteries solely or in combination with diabetes mellitus (DM), were analyzed. The malleolar pressure index (MPI), regional systolic pressure (RSP), velocity of the volume blood flow (VVBF), rheographic index (RI), using test with nitroglycerine, postocclusion venous pressure (POVP) and intaosseous pressure (IOP) in tibiae were studied. The RI reduction, parallel to the arterial ischemia progression, was established. The test indices with nitroglycerine in patients with obliterating atherosclerosis have reduced step by step. With coexistent DM the efficacy of nitroglycerine was practically absent. POVP is upgraded in patients of all the groups and it have lowered step by step in a laying position of the patient, and while transition into standing position--it have upgraded progressively with a progress of arterial ischemia. IOP have upgraded significantly in isolated obliterating atherosclerosis in ischemia stage 3a and have lowered--in stage 3b. In coexistent DM IOP is upgraded in ischemia stage 3b also.

Results of examination and treatment of 339 patients, suffering an acute varicothrombophlebitis, complicated by transfascial thrombosis, were analyzed. Indications for surgical prophylaxis of pulmonary thromboembolism in transfascial thrombosis in a system of vena cava inferior were studied. After the operation in all the patients, while presence of transfascial thrombosis, not taking into account the operation radicalism, the treatment was prescribed, similar to that for the deep veins thrombosis. In the deep veins thrombosis, combined with superficial varicothrombophlebitis , an access for excision of a small subcutaneous vein of lower extremity must be differentiated, depending on spreading of thrombotic occlusion and localization of the calf veins inflowing place. Introduction of active surgical tactic in presence of floating thrombus in the anklepopliteal venous segment secures conduction of effective prophylaxis of pulmonary thromboembolism

The results of the anatomical study of the inferior vena cava (IVC) and its tributaries on 27 fresh cadavers were analysed. It was established that in past hepatic part of IVC fall from 7 to 23 veins. The diameter of the main hepatic veins on average 12.3 mm, and back 4.8 mm. In 63% of cases between the main and back hepatic veins have a free box of length 10 18 mm. Lumbar vein 2 8 pairs of branches in 92.6% of cases merge and flow into the IVC by one trunk, often closer to her left hemi circle. The diameter of the joint lumbar vein average 5.2 mm. Upper joint lumbar vein falls into the IVC at a distance of 13 23 mm from the confluence of the right renal vein. Back hepatic and joint lumbar vein may be a source of intraoperative bleeding, that is difficult to control. Identified anatomical features tributaries of IVC below the diaphragm should be borne in mind when removing blood clots from the IVC.

In 36 patients, suffering trophic ulcers on a chronic venous insufficiency background in a decompensated stage (C6 in accordance to CEAP), echoscleroobliteration of perforant veins, using a "foam-form" method in accordance to Tessari, was performed. In 29 patients postrombophlebitic syndrome in incomplete recanalization stage was diagnosed, in 7 recurrence of varicose disease of the lower extremities. In all the patients during echoscleroobliteration there was possible to obliterate the insufficient perforant veins, in 3 patients two perforant veins were obliterated in each of them. In a one week a pathological blood flow along perforant veins, in accordance to data of ultrasound duplex scanning, was absent. This effect lasted during 6 mo in 29 (80.6%) patients. In 25 (69.4%) patients a trophic ulcers healing was achieved in 1 - 3 mo. In a one year in 30 (83.3%) patients a stable obliteration was noted, in 3 (8.3%) - partial recanalization, in 3 (8.3%) - complete recanalization of perforant veins.

Surgical treatment was conducted in 81 patients, suffering renocellular cancer (RCC), complicated by a renal vein and vena cava inferior thrombosis. According to the Mayo clinic classification, the level of a tumoral thrombus spread was established: the 0 level--in 37 patients, the level I--in 19, the level II--in 17, the level III --in 6, and the level IV--in 2. There were substantiated the optimal surgical accesses and technique of radical nephrectomy and thrombectomy for RCC, complicated by a renal vein and vena cava inferior thrombosis. It is recommended to apply transabdominal accesses: the extended median laparotomic, bilateral subcostal of a "Chevron" or "Mercedes" type. There was shown, that the access choice depends on the level of the tumoral thrombus localization.

Main reasons and frequency of early postoperative thrombotic complications were analyzed. The frequency of early postoperative thrombosis in vessels of femoro-popliteal-tibial segment composed 19.1%. The most frequency of early reocclusion observed after the femoro-tibial reconstructive operations (in 32.4% patients), the least--after femoro-popliteal grafting at above knee level (in 14.1%). The main reason for early reocclusion is an inadequate estimation of distal arteries damage.
