RESUMO
Conn's syndrome, also known as primary hyperaldosteronism, is a disease of the adrenal glands characterized by autonomous and excessive aldosterone production, leading to sodium retention and a fall in serum potassium. It may be associated with long standing hypertension, and cardiac and neurological complications. A 51 year old, hypertensive, male patient presented with generalised muscle weakness and hypokalemia. The patient was diagnosed to have benign adrenal adenoma with Conn's syndrome and was scheduled for laparoscopic adrenalectomy. We used epidural analgesia followed by induction of general anesthesia. Intraoperative course was uneventful except for one episode of hypotension.Unilateral or bilateral adrenalectomy may be performed to treat Conn's syndrome depending on the pathology. Replacement corticosteroid and mineralocorticoid therapy is required for all patients undergoing bilateral adrenalectomy and occasionally in those undergoing unilateral adrenalectomy. Following surgery, the cure rate for hyperaldosteronism may be as high as 60-77%, though it may take a year or more for hypertension to resolve
