title: Successful removal of a ruptured silastic percutaneous central venous catheter in a tiny premature infant.
abstract: The spontaneous rupture of a Silastic catheter is a rare occurrence. We describe our experience of managing a tiny premature infant with embolization of a Silastic percutaneous central venous catheter (PCVC) and discuss the possible mechanisms of the embolization. A 28-week, 980 g, preterm male infant received a Silastic PCVC (Epicutaneo Cava Catheter, Vygon, Germany) for parenteral nutritional support at 4 days of age. The catheter was introduced percutaneously and advanced without difficulty through the right antecubital vein, and was subsequently withdrawn 2 cm following confirmation of tip position using radiography. A following chest radiograph, taken 15 hours later, showed rupture of the catheter, and an echocardiogram revealed a piece of the catheter had lodged between the right atrium and the right ventricle. The dislodged fragment of the catheter was retrieved successfully using a snare catheter (Microvena, White Bear Lake, Minn) by a pediatric cardiologist without complications. We want to stress that clinicians should be aware that rupture of the catheter is rare and can also occur asymptomatically and that an embolized fragment can be safely removed without extensive surgical manipulation, even in a tiny premature infant.
