To explore the relationship between perioperative blood pressure and catecholamine concentrations in adrenal venous blood and peripheral venous blood in hypertensive patients with primary aldosteronism (PA) who underwent percutaneous selective adrenal artery embolization (SAAE). In order to elucidate the related phenomena and possible mechanisms of blood pressure fluctuations caused by SAAE treatment in hypertensive patients with PA.
