This paper provides experience of surgical treatment administered to 244 patients suffering from arterial hypertension of suprarenal origin. Good and satisfactory results were observed at 96.3% of cases. The most effective were the operations performed on account of pheochromocytoma, benign corticosteroma, primary hyperaldosteronism, and Cushing's syndrome. Unacceptable results of the surgical treatment were stated in cases of malignant corticosteroma. The authors emphasize the importance of early diagnostics and opportune surgical treatment under hormone-producing suprarenal gland tumors before the irreversible changes in the cardiovascular system and in kidneys may appear.
