What are all the causes and symptoms of renal artery stenosis?

High blood presure: Most commonly it is due to build up of plaque in the kidney blood vessels, causing narrowing of the renal /kidney arteries and decreased blood flow to the organ. This may result in loss of function and high blood pressure.Most patients are unaware this is occuring.

Depends on risk: There are two major causes of the renal arterial lesions: atherosclerosis and fibromuscular dysplasia. There are rare less frequent causes, such as congenital.

Aretherosclerosis: Of renal artery is most common cause, next is fibromuscular dyplasia. Other causes are uncommon & include neurofibromatosis with a fibroma causing stenosis, arteritis or a renal artery aneurism.. Ras itself does not cause symptoms & found during or following work-uop for refractory hypertension. Uncontrolled hypertension can cause headaches & at worst acute heart failure.
