Charny PAN, et al. - Authors scrutinized the risk of catheter-associated thrombosis (CAT) between peripherally inserted central catheters (PICCs) and tunneled central venous catheters in children with leukemia, aged <18 years and admitted for treatment between February 2008 and April 2014. It was observed that CAT incidence was 1.5% in the conventional tunneled catheter group and 10.2% in the PICC group. An increased risk was reported of CAT due to the use of PICCs in children with leukemia in comparison with the use of conventional tunneled catheters.
