Abstract: The shedding of central venous Catheter-Retated Thrombus may lead to fatal pulmonary embolism. In the early stage of thrombus formation, patients often have no obvious clinical symptoms. Therefore, early identification of high-risk groups is very important. In this paper, published risk prediction models at home and abroad were reviewed from the aspects of the construction process of prediction models, influencing factors of central venous Catheter-Related Thrombosis, evaluation indicators and application effects. Characteristics and limitations of existing prediction models were analyzed to provide references for clinical identification of high-risk patients with central venous Catheter-Related Thrombosis.
