Giant Pheochromocytoma Resection Using Partial Cardiopulmonary Bypass and Blood Purification Therapy.

A 44-year-old man was diagnosed with a giant pheochromocytoma in the right retroperitoneal cavity following treatment for heart failure. Subsequent to improvement in cardiac function, the patient underwent a laparotomy to excise the tumor. Due to its considerable size, partial cardiopulmonary bypass and blood purification therapy were initiated to stabilize hemodynamics during the surgical intervention.
