In this comparative study of catheter materials used in central venous catheterization (CVC) into large veins, the overall frequency of CVC-induced thrombosis was 12%, which was significantly less common with Teflon® and heparinized polyethylene than with siliconizedpolyethylene.
Abstract
Abstract In this comparative study of catheter materials used in central venous catheterization (CVC) into large veins, the overall frequency of CVC‐induced thrombosis was 12%. A 20% incidence of CVC‐induced thrombosis with siliconized polyethylene catheter, 9% with Teflon ® catheter, and 6% with heparinized polyethylene catheter was seen. Thrombosis thus was significantly less common with Teflon ® and heparinized polyethylene than with siliconized polyethylene ( p <0.05). Repeat arm phlebography was performed in 15 patients and revealed no late formation or progression of thrombosis. Pulmonary embolism appeared in 2 patients and was fatal in one of them.
