title: Evaluation of long-term central venous patency in children with chronic venous catheters using image-directed Doppler ultrasonography.
abstract: All children in the Oncology Unit in the Royal Hospital for Sick Children, Edinburgh who had had long-term central venous catheters removed between 1987 and 1991 underwent central venous assessment by image-directed Doppler ultrasound scanning techniques. In this study, the implant vein remained patent after decannulation, and we believe should be re-accessed rather than moving to another site.
