The treatment of unilateral atherosclerotic renal artery stenosis will be reviewed here. The primary concern with unilateral renal artery disease focuses on its role in raising systemic arterial pressure. Clinical clues suggesting the presence of renovascular hypertension and establishing the diagnosis of renal artery stenosis, treatment of ...
Renal artery stenosis is narrowing of the one or both of renal arteries. It is the major cause of hypertension and according to some reports is the cause of hypertension in 1% to 10% of the 50 million people in the United States. Atherosclerosis or fibromuscular dysplasia most often cause it.
The clinical features and clues to a diagnosis of renovascular hypertension, as well as the treatment of renovascular hypertension and ischemic nephropathy, are presented elsewhere: (See "Evaluation of secondary hypertension", section on 'Clinical clues for renovascular hypertension'.)
Significant renal artery stenosis (RAS) can cause or result in deterioration of arterial hypertension and may promote the development of renal insufficiency. The activation of the renin-angiotensin-aldosterone system results in structural heart disease and may impact patient survival.

Treatment for renal artery stenosis may involve lifestyle changes, medication and a procedure to restore blood flow to the kidneys. Sometimes a combination of treatments is the best approach. Depending on your overall health and symptoms, you may not need any specific treatment.
Renal artery stenosis (RAS) is typically due to atherosclerotic disease or fibromuscular dysplasia. RAS often presents with accelerated or difficult-to-control hypertension. Worsening kidney function, especially after initiating renin-angiotensin blockade, and recurrent flash pulmonary oedema are common features.

Renal artery stenosis is the narrowing of one or more arteries that carry blood to your kidneys (renal arteries). Narrowing of the arteries prevents enough oxygen-rich blood from reaching your kidneys. Your kidneys need adequate blood flow to help filter waste products and remove excess fluids.
Renal artery stenosis (RAS) (plural: stenoses) refers to a narrowing of a renal artery. When the process occurs slowly, it leads to secondary hypertension. Acute renal artery stenosis does not lead to hypersecretion of renin.
