BACKGROUND: Primary hyperaldosteronism (PHA) frequently causes secondary hypertension and is a surgically amenable disease if associated with unilateral adenoma. Patients who underwent laparoscopic adrenalectomy at the authors' department were followed to identify clinical parameters that predict resolution of hypertension.
METHODS: All patients with PHA and adrenalectomy from 1993 to 2009 were identified. Charts and follow-up data were reviewed for clinical parameters and hormone levels. Univariate and multivariate analysis were performed with SPSS 15.0.
RESULTS: A cohort of 30 female and 24 male patients underwent laparoscopic adrenalectomy. Hypokalemia was observed in 47/54 (87%) patients. Twenty patients (37%) were cured without any further need of antihypertensive medication, 20 (37%) patients experienced an improvement in hypertension, and 14 (26%) patients remain unaffected. Consequently, hypertension was resolved or improved in 40/54 (74%) patients. A shorter duration of hypertension (<6 years), the number of antihypertensive drugs (<3), and the serum creatinine level (<1.3 mmol/l) were independent predictors of resolution of hypertension in a multivariate analysis. At final follow-up after a mean of 49 ± 40 months, resolution of hypertension was observed in 17/30 (57%) patients. Interestingly, in 10/17 patients a period longer than 12 months was required before a resolution of hypertension was observed. Coexistent hyperplasia, which was observed in 30% of patients, did not correlate with outcome.
CONCLUSIONS: In 50% of patients with PHA, hypertension resolves after laparoscopic adrenalectomy, but the process may require more than 12 months. Patients with a duration of hypertension of more than 6 years, more than 3 antihypertensive drugs, and elevated serum creatinine have a higher risk of persistent hypertension after surgery. Coexistent hyperplasia in the resected adrenal gland is not associated with persistent hypertension.
