Abstract

Primary aldosteronism is present in approximately 1 percent of hypertensive patients, and is rarely associated with pregnancy. We report a case of unilateral aldosterone producing adenoma in a pregnant woman. A 29-year-old woman was referred to with hypertension and proteinuria at 14 weeks' gestation. She had known that she had unilateral aldosterone producing adenoma for 18 months and refused medical or surgical treatment. She was prescribed antihypertensive medication and preformed laparoscopic adrenalectomy in left adrenal gland at 22 weeks' gestation. After adrenalectomy, her blood pressure was normal. At 29 weeks' gestation, she complained headache, and her blood pressure was 200/100 mmHg with pitting edema. We thought preeclampsia and performed cesarean section. After the baby was delivered, she had uncontrolled hypertension, hypokalemia with persistent proteinuria. We checked plasma renin activitity, aldoterone and abdminopelvic computed tomography. We found remnant left adrenal adenoma and perfomed laparoscopic operation. After reoperation, her blood pressure was normal and no proteinuria.
