We encountered two cases of the catheters' cuttings at the implanted ports in whom a totally implantable catheter port (CV port) had been implanted. Case 1 was a 2-year-old girl who had been treated for myelodysplastic syndrome, and was under observation in complete remission status at our outpatient clinic. The catheter was cut 15 months after it had first been implanted, and had to be removed by venous incision, because it had entered the left subclavian vein. Case 2 was a 3-year-old girl with acute lymphoblastic leukemia, and the problem occurred during consolidation therapy, six months after the CV port had first been implanted. This cut catheter had entered the inferior vena cava. A basket catheter was introduced from the femoral vein to remove the cut catheter. The following are thought of as causes of catheter cutting at CV ports: (1) unexpected traction caused by growth and movement of the upper extremities, (2) poor quality of the catheter and its lock. It is necessary to watch for catheter cuttings at implanted ports as a serious complication of CV port implantation.
