Abstract
Totally implantable venous access devices are widely used in pediatric oncology. The
authors encountered a 10-year-old boy with implantation of the device at the age of
7 years owing to acute lymphoblastic leukemia. In the recent half-year, the device
was not used except for regular heparin flushing. However, hydrothorax occurred when
fluid therapy was required from the device during this admission. Thoracoscopic approach
showed extravascular migration and intrapleural malposition of the catheter. Intrapleural
migration of the extravascular portion of the catheter owing to irritation and pressure
necrosis of the pleura and gradual shortening of intravascular portion of the catheter
when the child grew up may be the pathogenesis of delayed extravascular migration
of the catheter.
