Clinical characteristics and risk factors of symptomatic central venous catheter-related deep vein thrombosis in children

Abstract

Objective To investigate the clinical features and risk factors in children with symptomatic central venous catheter-related deep vein thrombosis, and to provide guidence for clinical therapy. Methods The clinical data of 105 children with central venous catheter were retrospectively analyzed.According to the thrombosis or not, these children were classified into two groups: thrombosis group and non-thrombosis group.The risk factors influencing symptomatic central venous catheter-related deep vein thrombosis forming were identified by Logistic regression analysis. Results Among the 105 cases with central venous catheter, the male to female ratio was 68∶37; age ranged from 8.5 months to 13 years old with average age(5.5±4.0)years old.There were 98 cases in non-thrombosis group and 7 cases in thrombosis group.Factors such as age[(5.7±4.1)years old vs.(2.5±1.8)years old], central venous catheter dwell time[(6.1±2.3)d vs.(8.9±2.1)d], more than 7 days parenteral nutrition application(11/98 cases vs.5/7 cases)and more than 7 days intravenous application of mannitol(7/98 cases vs.4/7 cases)were found significantly different between the thrombosis group and non-thrombosis group(P<0.05). Multivariate Logistic regression analysis showed that more than 7 days parenteral nutrition application and intravenous mannitol were the risk factors of symptomatic central venous catheter-related deep vein thrombosis[OR=50.703(95%CI 3.258-789.056), OR=15.590(95%CI 1.196-203.146), P<0.05]. Conclusion Symptomatic central venous catheter-related deep vein thrombosis is a common complication of deep venous catheterization.It cause acute pulmonary embolism and some critical diseases, and influence the prognosis and prolong hospital stay.Application of intravenous nutrition more than 7 days and intravenous mannitol more than 7 days are the risk factors of symptomatic central venous catheter-related deep vein thrombosis.
