What are some alternative treatments for renal artery stenosis?

Stent or medical. There is no difference in outcomes when using a renal artery stent or medical therapy to treat renal artery stenosis. Therefore a person can get a stent placed by a vascular surgeon to treat the condition or a person can take multiple blood pressure medications without having to undergo surgery to treat the condition as well.
It depends. It depends on the degree of stenosis if it is more than 60% it certainly cause decrease blood flow to the kidneys therefore angioplasty (dilatation) might be necessary.
Medicine vs Stents. There is no difference in outcomes when using a stent or medical therapy to treat renal artery stenosis (ras). Therefore a person can get a stent placed by a vascular surgeon to treat the condition. However a person can take multiple blood pressure medications without having to undergo surgery to treat the condition as well.
A few options exist. First, we may observe only if we have good blood pressure and kidney function with no fluid overload with close monitoring by a nephrologist. If the case is not stable i.e. These factors are worse or not controlled then angioplasty is considered i.e. Ballooning with a stent placement may control the problem and save medication use. Bypass surgery is the last option.
Angioplasty/Surgery. Generally, the treatment for renal artery stenosis is angioplasty (stretching the artery open with a balloon) with or without a stent, depending on the situation. If the stenosis is in a bad place or is not able to be fixed with angioplasty, surgery is an option. Sometimes, the stenosis can just be followed if there is not a problem with blood pressure or the stenosis is not damaging the kidney.

What are some treatments for renal artery stenosis?

See below. Renal artery stenosis is narrowing of the kidney arteries most commonly due to cholesterol plaques accumulating inside the walls of the blood vessel.There are other causes as well. A cathetor can be inserted into the blood vessel and a balloon can be inflated to restore the lumen size. A stent is inserted to keep it open.There are surgical options in special circumstances, .

Can you tell me about renal artery stenosis?

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. Read more...

How do you usually diagnose renal artery stenosis?

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. Read more...
MRA or CTangio. We suspect ras when creatinine gets worst after using ace inhibitors . Triple phase nuclear scans and nuclear renal study with Captopril stimulation may help as screening tests. Doppler ultrasound is difficult and unreliable at present. Only after stents are placed in the stenosis renal arteries if the renal numbers get better we are assured the diagnosis was correct. Mra or ct angio are riskier. Read more...

Should renal artery stenosis be treated using stenting or bypass?

Depends. If the artery is suitable for stenting, that is much simpler and less invasive, done through a 2mm hole in your groin under local anesthesia. Surgery requires an extensive abdominal surgery, clamping the aorta, tying off the renal artery, cutting it off and re-implanting it on the aorta. Renal artery stenosis can lead to difficult to control bp, decreased kidney function and flash pulmonary edema. Read more...
