OBJECTIVES: To identify risk factors, including aortic calcification, for persistent hypertension in primary aldosteronism patients undergoing laparoscopic adrenalectomy.
METHODS: Between October 2000 and October 2015, we carried out 101 consecutive laparoscopic adrenalectomies for unilateral primary aldosteronism. Of these, 95 cases with at least 1 year of postoperative follow up were included. These were divided into two study groups based on whether they had normal blood pressure without antihypertensive medications (resolved group) or still required medications (unresolved group) at 1 year after surgery. Variables included age, sex, body mass index, history of hypertension, dosage of antihypertensive medication score, presence of type 2 diabetes, subclinical Cushing syndrome, preoperative renal function, aldosteronoma resolution score and abdominal calcification index. Univariate and multivariate logistic regression analyses were used to assess independent risk factors for persistent hypertension 1 year after surgery.
RESULTS: The complete resolution of hypertension without antihypertensive medication 1 year after adrenalectomy was 36 out of 95 (38%). The preoperative antihypertensive medication score, systolic blood pressure and abdominal calcification index were significantly higher, and the aldosteronoma resolution score were significantly lower in the unresolved group than in the resolved group. Using multivariate logistic regression analysis, independent risk factors significantly correlating with persistent hypertension 1 year after surgery were aldosteronoma resolution score and abdominal calcification index.
CONCLUSIONS: Laparoscopic adrenalectomy for primary aldosteronism is effective in improving blood pressure and reducing the need for antihypertensive medications. Aldosteronoma resolution score and abdominal calcification index represent potential independent risk factors for persistent hypertension 1 year after surgery.
