本文报告６例原发性醛固酮增多症，采用双侧肾上腺静脉插管取血测定血浆肾素活性及醛固酮水平，并比较患侧与健侧肾素活性及醛固酮水平的差异。结果为患侧醛固酮均明显高于健侧，与手术及病理结果相符，认为此法为一精确的诊断及定位方法。 This article reports 6 cases of primary aldosteronism, using bilateral adrenal vein catheter blood plasma renin activity and aldosterone levels, and ipsilateral and contralateral renin activity and aldosterone levels were compared. The results showed that the ipsilateral aldosterone in the affected side was significantly higher than that in the uninjured side, which was consistent with the surgical and pathological findings. This method was considered as an accurate diagnosis and localization method.
