  • Title: [Porto-caval transposition and the course of vasorenal hypertension].

    Abstract:
    The study concerns the effect of angiotensin II when infused into the systemic and portal blood flow upon the general and renal haemodynamics in normal dogs and in hypertensive animals, as well as the effect of the operation of porto-caval transposition upon the course of renovascular hypertension. When peptide is infused, at a rate that causes a moderate pressor effect, into the systemic blood flow of normal animals, an antidiuretic and antinatriuretic effect is obtained, in hypertensive animals--an increase of diuresis, natriuresis and a less distinct pressor effect are obtained. When angiotensin II is infused into the portal flow, a less distinct pressor and renal effect is seen in animals with renovascular hypertension. The operation of porto-caval transposition of the vessels results in a hypotensive effect in the animals with renovascular hypertension.
