Open adrenalectomy surgery: an obsolete technique? About a case of Conn's syndrome.

The authors report a case of an adenoma of Conn brought to their attention and treated by them in open surgery. The forms of primary hyperaldosteronism are essentially referable: 1) to the adenoma producing aldosterone, responsive to the ACTH, which represents the most common form (60-70%), responsive to surgery and with full recovery (70%) of cases. 2) to the bilateral hyperplasia, responsive to the angiotensine II, 25-30% of the cases, susceptible to medical therapy with receptorial antagonists of aldosterone.
