Abstract : Both an increase and a decrease in total renal vascular resistance, following a period of total renal artery occlusion, have been reported from this laboratory. The duration of the occlusive period and height of the perfusion pressure were found to prescribe consistently the hemodynamic response. The present study, using adult mongrel dogs, indicates that, following a period of partial occlusion, in a critical range of renal artery pressure (40% to 50% of control), intrarenal hemodynamic changes mimicked those seen after total obstruction of blood flow. Reactive hyperemia was not observed. (Author)
