Intrapericardial infusion of 5-fluorouracil. An unusual complication of a Hickman catheter.

Venous access devices (VAD) have become an important tool in the management of patients with cancer. Multiple complications can occur as a consequence of insertion of a VAD. The authors report a case of a Hickman catheter perforating the wall of the superior vena cava into the pericardium, resulting in accidental intrapericardial infusion of 5-fluorouracil (5-FU). Pericarditis and cardiac arrhythmias developed, but the patient did not have cardiac tamponade. She recovered from the event without apparent chronic cardiac dysfunction.
