Port device central venous access in children with chronic renal disease--personal experience]

The application of central venous lines in children has been widely accepted in the case of pediatric cancer treatment. This is of particular importance when the treatment must be continued during the long period of time. The indication to long-term application of central venous lines became significantly frequent within last years. They are necessary in the treatment of chronic pediatric patients, in whom the central venous line allows continuous access for medication, parenteral rehydration, nutrition and frequent blood sampling.In the current study authors present their experience in subcutaneous port devices application in children with kidney disease. The case history data obtained from 8 children were retrospectively analysed. In these children subcutaneous port devices were applied for mean 26.7 months (totally 9 port devices). The mean age at the time of implantation was 2.2 years, and the mean body weight--10.6 kg.Peripheral venous access in all children was bad. In one child during the time of implantation the hematoma of coli and chest was present. Infectious complications connected with implanted port device were not detected. Thrombotic complications were present in 6 children with chronic renal failure--in 5 the lumen of port device has been successfully recanalysed, in 3 cases even several times. In 1 child the thrombus on the tip of central venous line was detected. In 2 children the removal of port device was necessary because of breakage of venous line and in the second case because of port device thrombosis. Two children died with functioning port device. The cause of death was not connected with implanted port device.The application of subcutaneous port devices definitely improved the comfort of treatment but was significantly associated with thrombotic complications. Infectious complications were not detected as compared to hematological group of patients.
