Renovascular hypertension (RVH) is a type of secondary hypertension, where high blood pressure develops secondary to renal artery disease.
Approximately 2.5% (range 0.5-5%) of hypertensive patients will have RVH as a cause 2,3.
There are a number of conditions that can cause RVH 1-3:
There are other causes that can cause renal artery obstruction but these are much rarer 2,3:
- renal artery dissection (e.g. from trauma or aortic dissection)
- renal infarction
- Page kidney
- renal artery embolism or thrombosis
- EVAR stent graft
- encircling tumour (e.g. pheochromocytoma)
- radiation-induced fibrosis
- polyarteritis nodosa
