[Use of central venous catheters implanted subcutaneously in children with neoplasms]

The use of totally implantable right atrial catheters was evaluated in pediatric oncology patients. From September 15, 1987 to March 31, 1989, 26 catheters were inserted in patients (1 year to 20 years of age) with the following diagnosis: acute leukemia (6), osteosarcoma (5), lymphoma (4), central nervous system tumors (6), osteosarcoma (5), lymphoma (4), central nervous system tumors (6) and other solid tumors (5). Total number of catheter days was 5,475. The catheters were maintained for a mean of 210 days (range 10-534). Complications included: documented local infection in 1 patient, successfully treated with antibiotics without removing the catheter and transient obstructions resolved with injection of heparin or urokinase in other children. The use of these right atrial catheters has been widely accepted by patients and families as well as by the health team. Complications have been minimal. Our experience confirms that these catheters contribute to improving quality of life in pediatric patients with neoplasms.
