Recently, Peking University Third Hospital performed a simultaneous pheochromocytoma resection and mitral valve replacement for a patient. According to the data search, only 2 cases of this kind of surgery have been performed internationally, and there is no report in China. The patient, Zhang Tietou, 56 years old, lives in a rural area in Hebei. He started to suffer from diabetes in 2003, and gradually developed paroxysmal hypertension, heart failure, dyspnea, bilateral lower limb edema, and adrenal area occupancy in 2004. In June this year, Zhang Tietou went to Peking University Third Hospital for medical treatment. After diagnosis, the pheochromocytoma on the patient’s adrenal gland was about 4~5cm and had to be removed. The patient had a more serious heart lesion and extremely poor cardiac function, which made the surgery too risky. After two weeks of medication, the long-standing state of high tension of the pheochromocytoma on the peripheral vessels improved, but the patient’s cardiac function became even worse, with several episodes of heart failure at night, rapid atrial fibrillation, anterior mitral valve leaflet prolapse, and incomplete closure. His surgical options were fully discussed by the urology and cardiac surgery departments of the hospital. The experts believed that if only the pheochromocytoma was removed, the patient’s heart would likely not even tolerate anesthesia; and if only the mitral valve was replaced without cutting the pheochromocytoma, its secretion of catecholamines would cause a dramatic increase in blood pressure, which would likely lead to the patient’s sudden death. After discussion, the experts boldly “ pat ”, two surgeries at the same time to do. Recently, Director Ma Lulin and Deputy Chief Physician Zhao Lei of the Department of Urology and Director Sun Lingbo and Deputy Chief Physician Cui Zhongqi of the Department of Cardiac Surgery jointly completed the surgery for the patient. The patient was able to drink porridge on the second day after the surgery and was transferred out of the intensive care unit on the third day. As of press time yesterday, the patient’s blood pressure, heart rate and other physiological indicators were normal.
