Aims and objectives
Aldosterone has two basic functions: regulation of extracellular volume and regulation of potassium metabolism.
Primary hyperaldosteronism is the most common cause of secondary hypertension with a prevalence of approximately 5-20%.
Patients with primary hyperaldosteronism often take several drugs to control blood pressure.
They have hypokalemia and as a consequence polyuria,
polydipsia,
paresthesias,
weakness,
fatigue,
headaches etc.
In most cases (> 95%),
primary hyperaldosteronism is caused by an aldosterone-producing adenoma or bilateral adrenal hyperplasia.
(Figure 1)
The diagnosis of primary hyperaldosteronism is clinical and biochemical.
Once diagnosed,
the next step is identifying its etiology through imaging techniques and interventional procedures.
Adrenal vein sampling remains a “gold standard” procedure and allows to differentiate between unilateral (adenoma) and bilateral (hyperplasia) disease.
Patients with bilateral disease should be treated with mineralocorticoid receptor antagonist drugs,
while patients with unilateral disease should be treated with adrenalectomy.
(Figure 2)
The aim of this study is to presenting our center experience (last 10 years) in terms of establishing and implementing the adrenal vein sampling procedure.
