[The significance of the material of vascular catheters in the development of thrombotic complications in cava catheterization].

Based on 210 cases of putting polyurethane catheters through the subclavian vein the authors substantiate the significance of the catheter material for the development of the most frequent complications. In addition to the absence of clinically diagnosed thrombotic complications, the advantages of this material were confirmed in US investigation of tributaries of the vena cava superior in 27 patients with polyurethane cava catheters staying in the same position during 3 weeks. In all the patients there were no signs of a reaction of a central veins to the catheter.
