renovascular hypertension

Renovascular hypertension (RVH) is a type of secondary hypertension, where high blood pressure develops secondary to renal artery disease.

Epidemiology

Approximately 2.5% (range 0.5-5%) of hypertensive patients will have RVH as a cause .

Pathology

Etiology

There are a number of conditions that can cause RVH :

• atherosclerotic renal artery stenosis (~90%)
• fibromuscular dysplasia (second most common)

There are other causes that can cause renal artery obstruction but these are much rarer :

• renal artery dissection (e.g. from trauma or aortic dissection)
• renal infarction
• Page kidney
• renal artery embolism or thrombosis
• EVAR stent graft
• encircling tumor (e.g. pheochromocytoma)
• radiation-induced fibrosis
• polyarteritis nodosa

Treatment and prognosis

Treatment of the underlying cause has variable effect . RVH can lead to ischemic nephropathy and end-stage renal failure .
