  • Title: [Surgery of Conn's syndrome. Apropos of 16 cases].
    Author: Henry JF, Borsarelli J, Laglace R, Audiffret J.
    Journal: J Chir (Paris); 1986 Feb; 123(2):124-8. PubMed ID: 3700500.
    Abstract:
    Operation for tumors responsible for a Conn's syndrome was performed in 16 patients, 11 women and 5 men, over a period of 13 years, the average time before diagnosis being 5 1/2 years. All patients presented hypertension, permanent in 14 and paroxysmal in 2 cases while blood potassium levels were below 3 mmol/l in all patients. Diagnosis was confirmed by elevation of plasma aldosterone and of urine tetrahydroaldosterone, associated with low plasma renin activity not responding to a stimulus. The tumor was demonstrated by imaging in 15 cases before operation and its mean size was 1.7 cm. Investigatory methods for diagnosis and localization are discussed. One patient died during the immediate post-operative period from decompensated cardiac failure. Long-term review showed persistent hypertension in 5 patients but electrolyte disturbances were corrected in all cases. Lack of consistency of results of surgical reduction in case of hyperplasia suggests that only patients with hyperaldosteronism related to an adrenal cortex tumor should be operated upon.
