Super Selective Adrenal Artery Embolization for Primary Aldosteronism: a Prospective Cohort Study(SAAE-PA)

The objective of this study was to evaluate the efficacy and safety of adrenal vein blood extraction for primary aldosteronism classification and adrenal artery embolization in the treatment of primary aldosteronism, to provide new evidence plan for the diagnosis and treatment of primary aldosteronism, and to promote the development of adrenal artery embolization as a new treatment for primary aldosteronism.

As one of the causes of refractory secondary hypertension, primary aldosteronism is usually treated with drug therapy and adrenalectomy, but the therapeutic effect of these regimens is limited in some people. Adrenal vein blood collection is a method to identify the types of primary hyperaldosteronism by comparing the ratio of aldosterone in venous blood by selective catheterization into adrenal vein. Superselective adrenal artery embolization is a catheter-based percutaneous cavitary procedure in which ethanol is selectively injected into the adrenal artery to ablate part of the adrenal gland. Recently, it has been used as an alternative therapy for patients with unilateral aldosterone-producing adenomas as well as idiopathic hyperaldosteronism without obvious adenomas. This is a prospective, multicenter, randomized controlled study in Xinjiang to explore the potential of SAAE as a treatment.
