Résumé : In patients with clinical or experimental arteriovenous aneurysms, systemic vascular resistances are decreased, cardiac output is increased, sometimes very much so, and heart rate is accelerated. Temporary or definitive occlusion of the aneurysm decreases blood pressure and stroke output, and slows heart rate down (Branham's phenomenon). Increased cardiac work, related to increased cardiac output, brings out cardiac failure. At that time, left and right cardiac and pulmonary arterial pressures are increased; cardiac output decreases but remains above normal figures; it is, as a matter of fact, insufficient to meet the body requirements in oxygen. On effort, these patients behave as other cases of cardiac failure: pulmonary arterial pressures become definitely higher while cardiac output does not increase as much as it should. In Paget's disease, hemodynamic changes are more or less similar to those observed in patients with peripheral arteriovenous aneurysms. © 1965 Dr. Dietrich Steinkopff Verlag.
