Definitions
Renovascular disease (RVD) is a complex entity involving renal arterial lesions, renal disease, and hypertension. The relationships between these three entities are variable from patient to patient and difficult to assess, but their severity and their association increase the patient's cardiovascular and renal risks.
Renovascular hypertension (RVH) is a reversible cause of hypertension secondary to a decrease in renal perfusion pressure, which activates the renin–angiotensin system and leads to the release of renin and the production of angiotensin II (angiotensin II increases sodium reabsorption and induces postglomerular and systemic arterial vasoconstriction, causing renovascular hypertension). The prevalence of RVH is around 1% among hypertensive patients.
Renal artery stenosis(RAS) is the main cause of RVH, but small‐vessel intrarenal vascular disease can also be responsible for it. Its prevalence is...
