Primary hyperaldosteronism. Analysis of risk factors associated with persistent postoperative hypertension.

Between 1983 and 1992, 24 patients with primary hyperaldosteronism were operated at our division. Among these, 21 had adrenal adenoma and constituted the subjects of our study. The aim of this retrospective study was to determine risk factors that could potentially lead to persistent arterial hypertension (5 cases or 23.9%). The variables of the univariate and the multivariate analyses were: sex, age, diameter of the neoplasm, preoperative duration of the hypertension, and familial hypertension. The analysis demonstrated no statistically significant difference between the resolution of hypertension and the variables. Though not statistically significant, the only variable that approached statistical significance (p < 0.11) was familial hypertension.
