Catheter Fragment Embolization: A Rare Yet Serious Complication of Catheter Use in Pediatric Oncology
Departments of 1Pediatric Hematology and Oncology, and 2Pediatric Cardiology, Acıbadem University Faculty of Medicine, İstanbul, Turkey Embolization is a rare but serious complication of venous central catheters in pediatric oncology. The reported cases in the literature are due in common to catheter ruptures. The most common cause is constant compression of the costoclavicular arch, known as “pinch-off” syndrome. We report a sevenyear- old boy in whom embolization occurred as a late complication. Difficulty in the dissection of dense collagen periportal fibrosis was the main problem during the extraction session. The embolization occurred 10 months later. In an elective setting, percutaneous retrieval techniques were used successfully to extract the catheter fragments, and full recovery was achieved. Keywords : catheter surgery, catheter complications, embolization, retrieval devices, pinch-off syndrome.
