Study of central venous catheter associated thrombosis in critically ill patients

Abstract

Venous thromboembolism (VTE) remains a major cause of morbidity and mortality. There are three factors that contribute to DVT.These factors are called Virchow's triad :venous stasis,hypercoagulability and changes in the endothelial blood vessel lining. Upper extremity deep vein thrombosis (UEDVT) is an increasingly recognized complication in medical ICU, especially after the increase in usage of central venous catheters (CVC) for different purposes.In our study we aimed to determine the prevelance and risk factors that make the incidence of central line associated deep venous thrombosis increase. This descriptive study was conducted on 80 critically ill patients with inserted central venous catheter. Venous duplex was done before, 5th and 10th day of (CVC) insertion.
