BACKGROUND: Superselective adrenal arterial embolization (SAAE) is an alternative treatment for patients with primary aldosteronism (PA). This single-center prospective cohort study aimed to compare the efficacy of SAAE with mineralocorticoid receptor antagonists (MRA) in treating patients with PA who refused unilateral adrenalectomy.
METHODS: Of the 140 PA patients who were enrolled in the study and completed 12-month follow-up, 74 patients underwent SAAE and 66 received MRA treatment. The clinical and biochemical outcome was compared at 1, 6, and 12 months after the procedure.
RESULTS: Baseline clinical and biochemical characteristics of the patients were similar between groups. Office, home, and ambulatory blood pressure reduction at 1 month after discharge was more pronounced in the SAAE group than MRA group (all P < 0.05) while the blood pressure reduction was comparable between the 2 groups at 6 and 12 months. Patients who underwent SAAE took less antihypertensive medications than the MRA group during 12-month follow-up (P < 0.01). Both SAAE and MRA treatment improved renin suppression, aldosterone-to-renin ratio elevation, and hypokalemia at 6 and 12 months, whereas only SAAE but not MRA reduced plasma aldosterone levels. Moreover, SAAE achieved higher rates of complete clinical and biochemical success than MRA (both P < 0.01). Logistic regression found that complete clinical and biochemical success was only directly associated with diagnosis of unilateral PA in contrast to bilateral PA (P < 0.01).
CONCLUSIONS: The present study provides evidence that SAAE is a reasonable choice of treatment in patients with either unilateral or bilateral PA in terms of clinical and biochemical outcomes. This study was registered at Chictr.org.cn (ChiCTR2100045896).
