[Interrelation between hemodynamic parameters and the functional state of components of the endocrine system in...

Ten patients with pheochromocytoma were examined before operation, 8 were examined 2-4 weeks after surgical treatment, and 30 in the long-term periods after elimination of hypercatecholaminemia. The patients with pheochromocytoma manifested activation of the renin-aldosterone system and inhibition of PGE2 secretion. In the long-term postoperative period, the level of aldosterone in the blood plasma was increased and that of PGE2 was reduced. In the patients with pheochromocytoma, the interrelation was discovered between the magnitude of arterial blood pressure and secretion of catecholamines, deoxycorticosterone, depressor prostaglandins. At different times after surgical treatment the central hemodynamics was found to be related to the level of mineralocorticoid hormones.
