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...

Diagnosed with Renal Artery Stenosis and resistant hypertension of 150/100 w/ 3 meds. Will resolving the stenosis correct the resistant hypertension?

Not always. Stenting is now mainly used in people who fail maximal medical therapy as the CORAL trial showed that's tenting as a first line treatment was not better than medical therapy for most people. If maximal medical therapy has failed then you may be a candidate for stenting or renal artery bypass surgery but even these do not always correct the problem but at present are the best further treatments a.

What are some alternative treatments for renal artery stenosis?

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. Read more...
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. Read more...

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. 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...
Neither, sometimes. The value of revascularizing renal artery stenosis remains quite uncertain. In patients requiring multiple drugs for blood pressure control, after stenting there may be a small decrease in the number of pills needed. Clinical trials to address these questions have not given a clear answer yet. Read more...
Rx of renal art sten. 33 asks Should renal artery stenosis (RAS) be treated by stenosis or bypass. RAS should only be treated if it is cause of high blood pressure, Only reliable way to tell is to collect blood from veins draining each kidney and measure hormone renin. If stenotic side side has high renin & meds fail to control BP then repair depends on what is causing blockage and how bad it is. I specialize in this. Read more...
