RESUMEN
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.

There were analyzed the results of examination and treatment of 455 patients, suffering deep veins thrombosis in a system of vena cava inferior, of whom 175 (38.5%) were operated on. Inclusion of ultrasound duplex scanning, roentgencontrast phlebography, multispiral computer tomography with intravenous contrasting, radionuclide phleboscintigraphy into complex of clinic-instrumental examination of the patients gives possibility to estimate the disorders of the main trunk and collateral venous blood flow in the deep veins thrombosis, as well as to substantiate indications and choice of the operative treatment method.
