Abstract
Angiographic studies of renal vascularity in dogs with arfonad-induced hypotension showed in most instances: slight decrease in the diameter of the main renal artery; increase in caliber of segmental and interlobar arteries with better opacification of the peripheral branches; prolonged circulation time with reduced renal blood flow; and good nephrogram intensity including the cortex, smooth in outline. Usually the kidney was reduced in size.Recovery from arfonad effects was slow.THAM injected intravenously usually produced no or only slight return of the hypotensive angiogram toward normal appearance.
