Question 1

what are usual signs of renal artery stenosis ?

Accepted Answer

High blood pressure: Renal artery stenosis is typically discovered for evaluation of high blood pressure.  Otherwise, it rarely would result in pain or other symptoms felt by a patient.

Question 2

can you explain renal artery stenosis?

Accepted Answer

Will try: Renal artery stenosis is a blockage of the blood flow to the kidney.  This may be associated with high blood pressure.  It can be diagnosed with a doppler ultrasound of the renal artery in suspected individuals, or some form of a renal angiogram (such as ct or mr angiograms).  The stenosis can be dilated sometimes resulting in a decrease in blood pressure levels.

Question 3

how do you usually diagnose renal artery stenosis?

Accepted Answer

Renal arter stenosis: The diagnosis is made with ultrasound dopplers to check blood flow rates that reveal waves created by the blockage, or arteriograms.Ultrasound has no risk, but is very  operator dependent and can be misleading in both over and under diagnosis.Arteriograms are more accurate, but only show an anatomic blockage, and don't help with functional testing.  Finding blocks doesn't mean they need treatment.

Question 4

what is the typical prognosis for renal artery stenosis?

Accepted Answer

Depends on type: Young people are different than older ones. The disease is slowly progressive esp in the atherosclerotic variety usually in older patients. So, newer research suggests that observation is equivalent to aggressive intervenion in most cases due to similar outcomes.

Question 5

what problems does renal artery stenosis typically cause?

Accepted Answer

Hypertension: Reduced renal blood flow causes the kidney to produce excess renin which causes hypertension. Most cases of stenosis can be managed by interventional radiologists placing a stent.

Question 6

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

Accepted Answer

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.

Question 7

what is the prognosis for someone with  renal artery stenosis?

Accepted Answer

Good: Medical management until stent needed. Don't go to stent too early. May not need stent if kidney already damaged.

Question 8

what is renal artery stenosis (ras)?

Accepted Answer

Narrowed artery(ies): Narrowing of one or both renal arteries that lead from the aorta to the kidneys is called renal artery stenosis. Causes are atherosclerosis or fibromuscular dysplasia (fmd). Fmd is a non-inflammatory, nonatherosclerotic process. Both atherosclerosis and fmd cause hypertension and can lead to kidney failure. Imaging should be done to establish the diagnosis. Kidney specialists usually treat this dx.

Question 9

how long is the recovery after angioplasty for renal artery stenosis?

Accepted Answer

Go home: Same day or next. Light activity 7 days.

Question 10

does ras stand for renal artery stenosis?

Accepted Answer

RAS = renal art sten: Yes at least is you are talking to a HTN Dr.
