A case of pheochromocytoma in a chronic hemodialysis patient resected by laparoscopic surgery under continuous hemodiafiltration

Abstract

A 52-year-old woman, who had been treated with hemodialysis for 32 years, developed hypertention early in the morning and hypotention during hemodialysis. Serum catecholamin levels were elevated, and abdominal CT and MRI showed a left adrenal tumor of 20 mm in diameter. I¹³¹-MIBG scintiscanning showed abnormal accumulations in the left adrenal gland, which was diagnosed as pheochromocytoma. Laparoscopic surgery was performed under continuous hemodiafiltration. During operation, blood pressure transiently decreased, probably because of reduced catecholamines which were removed through the continuous hemodiafiltration. The tumor was resected successfully and she was discharged on the 6th post-operative day uneventfully.
