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. ...Read more
Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more
RAS: RAS due to atherosclerosis (ASO) more often than fibromuscular disease (FMD) Medical treatment does not alter RAS but can control BP. RAS can progress to occlusion. Controlling ASO risk factors appropriate. Open renal bypass infrequent. Angioplasty/stent more common but controversial. PTA probably Rx of choice for FMD. PTA/stent for ASO if flash pulmonary edema, uncontrolled BP, renal failure. ...Read more
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, . ...Read more
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
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
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
Uncontrolled BP: When a patient who is taking 3 or 4 blood presure medicines but still has an elevated blood pressure, then they should be screened for renal artery stenosis (ras). Additionally, any individuals who are younger then 30 or older than 60 who have blood pressures in 200/100 range should also be checked. ...Read more
If indicated: The indication for this has been questioned but if its apropiate then a few days at best to let the groin heal up snd your fine. ...Read more
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! ...Read more
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. ...Read more
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. ...Read more
Renal artery stenose: 52 F asks prognosis of RAS. ANS: I specialize in this for over 50 years. A complex question that deserves a 2nd opinion from me. Depends on cause, prior treatment, other problems but almost all can be managed today by BP meds. ...Read more
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. ...Read more
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. ...Read more
Interventional XR Dr: At your age more likely due to fibromuscular dysplasia than arterio or athero-sclerosis. An experience interventional radiologist might be successfully able to dilate and stent stenotic arteries. Worth researching the best local facilities +/or consider second opinion at a major medical center such as mayo or cleveland clinics or in a major city. Good luck. ...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 ...Read more
Aretherosclerosis: Of renal artery is most common cause, next is fibromuscular dyplasia. Other causes are uncommon & include neurofibromatosis with a fibroma causing stenosis, arteritis or a renal artery aneurism. Ras itself does not cause symptoms & found during or following work-uop for refractory hypertension. Uncontrolled hypertension can cause headaches & at worst acute heart failure. ...Read more
High blood pressure:
Patients who have uncontrolled blood pressure despite 3 or more medications at maximal dosages are considered for possible secondary hypertension. Ras is a cause of secondary hypertension.
Also people who are younger than 35 or older than 65 who develop sudden or new onset hypertension, are usually screened.
Unexplained renal failure especially with different sized kidneys should be screened. ...Read more

Depends: Stenting of the renal arteries has been controversial. Definitely, no intervention needs to be considered if the narrowing is less than 60%. The setting where stenting has definitely been shown to be beneficial is when the kidney function is deteriorating and/or the kidney size is shrinking. Stenting doesn't always improve the blood pressure or kidney function- hence the controversy. ...Read more
2nd chf in a month with bnp 2500, now 196. Suspect renal artery stenosis as creatinine bounced back from 3.2 to 2.0 (1.5 before renal failure). Nj meadowlands hosp won't release sonography to me or nephro, insurance won't approve. How should I proceed?

I don't believe so: Frequent kidney infections may be related to incomplete treatment of a kidney or bladder infection, problems with urine drainage e.g.Kidney stone, tightness of the tube from the kidney to the bladder (urethral stricture), problems with the bladder which may lead to kidney infections.Renal artery stenosis is a blockage of the blood flow to the kidney. This may be assoc. W/ high blood pressure. ...Read more
