Stuck long-term indwelling central venous catheters in adolescents: three cases and a short topical review

We present three cases of fixated vascular injection ports. Two patients had cystic fibrosis and one had an immunological defect. All catheters were made from polyurethane and implanted in adolescent patients. Indwelling time were 6-8 years. One patient's catheter was entirely integrated in the vessel wall and impossible to remove. In the other two cases, catheters were removed with great difficulty by the interventional radiologists. These cases raise important questions concerning the maximum indwelling time and the choice of catheter material when implanting permanent central venous catheters (CVCs) in adolescents. Furthermore, it highlights the importance of not breaking a CVC in the attempt to remove it.
