Endocrine Hypertension: Primary Aldosteronism by Conn Syndrome Hipertensão de Causa Endócrina: Hiperaldosteronismo Primário por Síndrome de Conn

Abstract

Primary aldosteronism is one of the most prevalent causes of secondary hypertension. It is characterized by inappropriately high and partially autonomous aldosterone production by the adrenal gland. The diagnosis warrants a high aldosterone/renin ratio and, in some cases, a confirmatory test. The treatment is laparoscopic adrenalectomy or medical therapy with mineralocorticoid receptor antagonists.

The authors describe the case of a 55-year-old patient with hypokalemia and hypertension refractory to therapy for 16 years. The investigation was compatible with primary aldosteronism by aldosterone-producing adenoma. The patient underwent right laparoscopic adrenalectomy, with substantial improvement of symptomology. The case report aims to describe an important cause of secondary hypertension that if detected and managed adequately may allow the resolution of hypertension.
