Abstract: Objective The objective of this study was to investigate the correlation between D-dimer levels and the occurrence of catheter related thrombosis(CRT)in tumor patients.Methods A prospective study was performed on 100 cancer patients with deep venous catheterization.The plasma D-dimer and intravenous Doppler ultrasonography were used to observe the incidence,time and thrombus type of CRT.Results The incidence of CRT was 12.6%,and asymptomatic thrombosis accounted for 83.3%.58.3% of the thrombosis occurred within 2 weeks after catheterization,and 91.7% occurred within 4 weeks after catheterization.After 2 weeks of catheterization,the level of D-dimer in the thrombosis group was significantly higher than that in the non-thrombosis group(P=0.013).Conclusion Most of the CRT in tumor patients is formed within 4 weeks after deep venous catheterization.The proportion of asymptomatic thrombus is high,and dynamic monitoring of D-dimer may be helpful for early diagnosis.
