A premature, 1.0 kilogram infant developed an umbilical venous catheter thrombus which extended through the patent foramen ovale and into the left side of the heart. After consultation with the physicians, the perfusion team was asked to adapt the bypass pump as needed to perfuse the tiny baby. The preparation also included evaluation of a 14 and 16 gauge angiocatheter to be used in the event that the standard 8 Fr. cannula was not sufficient. The mycetoma was excised during circulation arrest. The hematocrit of 20% during bypass was increased to 29% during rewarming of the patient via hemoconcentration. The patient was hemodynamically stable postoperatively and was transferred back to the referring hospital several days later. The patient died six weeks later of sepsis.
