DETACHMENT OF THE CATHETER DISTAL END AND ITS MIGRATION IN THE BLOOD STREAM IN COURSE OF THE EXPLOITATION OF THE FULLY IMPLANTED DEVICE (VENOUS PORT-SYSTEM) AT A CHILD WITH ACUTE LYMPHOBLASTIC LEUKEMIA (СASE REPORT)

It is not possible to imagine the antitumor and supportive treatment in children oncology without permanent central venous access. The development and modernization of such systems caused the appearance of the central venous catheter (CVC) without external component. The external CVC has got several shortages during use, especially in children,s practice, while totally implanted port-systems not only have not got most of them, but have got a lot of advantages as well. All catheter associated complications can be conditionally divided into 2 groups: ones referred to the procedure of catheterization of central veins and ones developing in the process of CVC use. The base of the oncology and tumors, chemotherapy division has got the experience of use of infusion venous ports since February 2006. This article presents the clinical case of the mechanical complication development in the process of the port-system exploitation: detachment of the catheter distal end and its migration to the distal segment of the left distal pulmonary artery, as well as the tactics of the patient management.
