title: Calcified thrombus in the right atrium: a rare complication of long-term parenteral nutrition in a child.
abstract: A 5-year-old boy with short-bowel syndrome who receives home parenteral nutrition developed a calcified thrombus that involved the inferior vena cava (IVC) and the right atrium. Symptoms included 3 to 4 months of intermittent fever and 2 months of vague chest pain. Blood could not be aspirated from the IVC catheter and an IVC contrast study demonstrated the calcified thrombus. The intracardiac portion of the mass was removed surgically, but the IVC mass could not be completely excised. The boy developed a pericardial effusion 6 weeks after surgery. He was treated for this and 6 months after the initial surgery the patient was asymptomatic.
