During the past three years period, we used 34 Broviac catherters for long-term total parental nutrition in infants and children. The mean duration of a single catheter could be plolonged for 147 days, because accidental removal of the Broviac catheter was not occured. The incidence of removal of the catheter for total complications was one per 255 days, and the incidence of removal for sepsis was one per 291 days. Leaks or cracks of the catheters were seen in four tsmes. For further plolongation of catheter's life-span, the prevention of catheter damage should be considered.
