Insights
Long-term central venous catheters in pediatric oncology patients remained functional after removal. Image-directed Doppler ultrasound confirmed vein patency, suggesting re-access is a viable option.
Area of Science:
- Pediatric Oncology
- Vascular Access
- Diagnostic Imaging
Background:
- Long-term central venous catheters are crucial for pediatric oncology treatment.
- Assessing the patency of implant veins after catheter removal is important for future access.
- Previous methods for assessing vein patency were limited.
Purpose of the Study:
- To evaluate the patency of implant veins in pediatric oncology patients after long-term central venous catheter removal.
- To determine if re-accessing the original implant vein is feasible and beneficial.
Main Methods:
- A cohort of pediatric oncology patients who had central venous catheters removed between 1987 and 1991 were assessed.
- Image-directed Doppler ultrasound scanning techniques were employed for central venous assessment.
Main Results:
- The implant vein remained patent in all assessed children after catheter decannulation.
- Doppler ultrasound confirmed the continued functionality of the central veins.
Conclusions:
- The implant vein remains patent after long-term central venous catheter removal in pediatric oncology patients.
- Re-accessing the original implant vein is a recommended and effective strategy over establishing new venous access sites.
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.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
