Primary aldosteronism (PA) is one of the most common cause of endocrine and resistant hypertension. Current studies have shown that the activation of the renin-angiotensin-aldosterone system (RAAS) and the increased sympathetic nerve activity in the central or local tissue are the key mechanisms of high blood pressure and its organ damages.

The classical method for diagnosis of primary aldosteronism depends on the detection of peripheral venous blood aldosterone level, which is incapable of accurate positioning diagnosis. On the other hand, the current guidelines recommend that surgery and aldosterone receptor inhibitors were the only treatment for primary aldosteronism. However, only about 35% of aldosterone tumors and a small part of unilateral adrenal hyperplasia can be treated by surgery. More than 60% of idiopathic aldosteronism and bilateral adrenal hyperplasia need long-term drug therapy. However, long-term aldosterone inhibitor treatment may also cause hyperkalemia, male breast hyperplasia, female hirsutism and other adverse reactions.

Therefore, the investigators proposed that endovascular chemical partial ablation of the adrenal gland can lower the aldosterone level, reduce the blood pressure and recover the potassium metabolism balance. In order to confirm the above effects, the investigators conduct an open, prospective, positive controlled study in patients with primary aldosteronism patients (including aldosterone, idiopathic aldosteronism and adrenal hyperplasia). The effects on blood pressure, blood electrolytes, adrenal hormones, metabolic indexes, target organ damages were observed to explore the efficacy and safety of the endovascular ablation of the adrenal gland in the treatment of primary aldosteronism.
