title: Fiberoptic examination of the inferior vena cava during circulatory arrest for complete removal of renal cell carcinoma thrombus.
abstract: Renal cell carcinoma is known to invade the inferior vena cava and may extend its entire length. Profound hypothermic circulatory arrest has been demonstrated to be a very effective technique to facilitate removal of tumor thrombus from the cava while limiting the amount of blood loss. We describe an innovative method of ensuring complete removal of tumor thrombus from the retrohepatic cava with a fiberoptic bronchoscope introduced through the right atrium during profound hypothermic circulatory arrest. Fiberoptic examination of the cava and hepatic vein orifices under these circumstances will prevent incomplete removal of tumor.
