Unilateral adrenalectomy for primary hyperaldosteronism due to unilateral adrenal hyperplasia

Abstract

Primary hyperaldosteronism is an increasing cause of arterial hypertension, pathology that is increasingly important due to the associated outcomes such as acute myocardial infarction and cerebrovascular disease, among others. Different subtypes of hyperaldosteronism are described, being one of these unilateral hyperplasia, which is a rare entity. The case of a 32-year-old female patient with a history of arterial hypertension, in whom hypokalemia was documented, is presented. The relationship between plasma aldosterone and renin, which was elevated, was performed with aldosterone of 43.9 pg / mL after a saline load test, confirming a primary hyperaldosteronism. Unilateral adrenalectomy based on venous sampling of aldosterone was decided. The pathology showed normality suggesting hyperplasia. In postoperative follow-up, better control of blood pressure and normalization of the aldosterone level was achieved, thus demonstrating that when aldosterone lateralization is noticed by venous sampling, adrenalectomy provides an option for improvement.
