Question 1

why exactly are ace inhibitors contraindicated in renal artery stenosis?

Accepted Answer

It depends: On the clinical situation. Ace inhibitors are commonly used to control BP in renal artery stenosis and are not contraindicated. Their is this concern that ACE inhibitors may worsen ischemia to the stenotic kidney and for this reason patients have to be closely monitored.

Question 2

can you tell me about renal artery stenosis?

Accepted Answer

Narrow kidney artery: Renal artery stenosis is a narrowing of the kidney artery. In most cases it is a benign condition but does imply there is generalized atherosclerosis. In some cases it can cause a rise in blood pressure. In rare cases it may need treatment with an angioplasty and stent.

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

my father has renal artery stenosis--should he consider having an angiography/angioplasty?

Accepted Answer

Possibly yes: If he has severe hypertension not well controlled on multiple medications and/or deterioration in renal function in the setting of high grade renal artery stenosis, then renal artery angioplasty may be very beneficial.  Consultation with a nephrologist and vascular surgeon is indicated.  Good luck!

Question 5

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 6

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 7

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 8

what are some alternative names of renal artery stenosis ?

Accepted Answer

Ischemic nephropathy: Stenosis means narrowing, most commonly due to cholesterol plaque in blood vessels. This may lead to ischemia or lack of blood/oxygen to the tissue when extreme. Nephropathy is any condition/disease in the kidney.

Question 9

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 10

what is the definition or description of: renal artery stenosis?

Accepted Answer

Stenosis: Stenosis is narrowing so renal artery stenosis is narrowing of an artery that sends blood to you kidney.  The effect usually is your blood pressure goes up and in my experience this is the most difficult kind of high blood pressure to manage using medicines.  It usually requires some kind of repair - surgery or dilatation.
