Abstract:
Objective To study the current status of catheter - related thrombosis(CRT)in Chinese children through a retrospective analysis of the inpatients in the Department of Medicine,Beijing Children's Hospital Affiliated to Capital Medical University. Methods The clinical data of the inpatients with CRT from November 2010 to November 2013 were collected retrospectively,and the causes,clinical symptoms,diagnosis,treatment and prognosis were ana-lyzed. Results There were 42 cases of children with CRT in Beijing Children's Hospital Affiliated to Capital Medical University. Among the cases,the male to female ratio was 1. 0:0. 5;the median age of onset was 88(2 - 186)months with ﹤ 1 year old counted for 16. 7%(7 / 42 cases)and 13 - 14 years old counted for 11. 9%(5 / 42 cases);the distri-bution differences between the male and the female age were not significant(P = 0. 826). The median time from cathe-terization to CRT onset was 9(1 - 81)days,0 - 10 days after catheterization was the peak of onset(52. 5% ,21 / 40 ca-ses)followed by 10 - 20 days(35. 0% ,14 / 40 cases). The protopathy was usually hematologic tumor,kidney disease or deep fungal infection. Slightly more cases developed CRT on the right side(57. 1% ,24 / 42 cases)than on the left side (38. 1% ,18 / 42 cases). All cases were diagnosed by using B - ultrasound,of whom 28. 6%(12 / 42 cases)were symp-tom - free. After being diagnosed,7. 1%(3 / 42 cases)were treated with conservative methods such as immobilization of the affected limbs and hot compress;7. 1%(3 / 42 cases)had catheter removed;anticoagulant and/ or thrombolytics after catheter removal used in 33. 3% patients(14 / 42 cases). After 1 week,22 cases were reviewed,of whom 54. 5%(12 / 22 cases)had thrombosis reduced(all with intervention),thrombosis growing in 22. 7% patients(5 / 22 cases), and thrombosis did not change in 22. 7% patients(5 / 22 cases). Three cases needed re - catheterization after catheter removal,and all of 3 cases had CRT recurrences(100% ). Conclusions CRT is more common among infants and senior children. CRT usually develops within 20 days after catheterization. Children with hematologic tumor,kidney disease or deep fungal infection are more likely to have CRT. Routine ultrasound test should be conducted to monitor CRT in catheterized children. Once CRT is diagnosed,patients need to be treated with anticoagulants and/ or thrombo-lytics. Catheter should also be removed if necessary. Recatheterization can result in CRT recurrence.
