Artery (Definition)

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

What are the treatments for  renal artery stenosis?

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

How do you usually diagnose renal artery stenosis?

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

Should renal artery stenosis be treated using stenting or bypass?

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

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

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

Can you explain renal artery stenosis?

Can you explain renal artery stenosis?

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

What is renal artery stenosis (ras)?

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
