WebRenal hypertension (or renovascular hypertension) is high blood pressure caused by the narrowing of your arteries that carry blood to your kidneys. It is also sometimes called renal artery stenosis. Because your kidneys are not getting enough blood, they react by making a hormone that makes your blood pressure rise. WebIn renal allografts, this high vascular resistance indicates graft dys-function and correlates with increased risk of graft loss. The diagnostic implications of reversed diastolic flow are moderately ambiguous because reversed diastolic flow can have an array of causes, that require different management and have varied outcomes.
