Use of veno-venous bypass for resection of malignant pheochromocytoma with vena caval thrombus
Surgical management of malignant pheochromocytoma with tumor-induced venous obstruction involving the entrance to the right atrium is challenging. The risk of marked hypotension and hemodynamic instability following clamping of the vena cava is increased as a consequence of the sudden decrease in circulating catecholamines. The use of cardiac bypass, however is burdened with additional operating time and coagulopathy. The present report illustrates that veno-venous bypass is a valuable tool during resection of phenochromocytoma with a large vena caval tumor thrombus.
