How do you typically diagnose renal artery occlusion?

How do you typically diagnose renal artery occlusion?

See below: The gold standard for detecting renal artery occlusion is a renal angiogram, which is injecting a iodinated dye into the blood vessel and taking images. The dye itself can cause some reversible renal injury, and should be used weighing the risk and benefit. Other rare but serious complication is cholesterol embolii syndrome. Other tests eg ultrasound and MRI may not be conclusive. ...Read more

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 common symptoms of a renal artery occlusion?

What are the common symptoms of a renal artery occlusion?

No common symptoms: This problem is most commonly found, without symptoms, during testing for high blood pressure. The common causes are chronic occlusion from atherosclerosis or hyperplasia of the artery. Acute embolic occlusion may result in severe flank pain. This is uncommon. ...Read more

What are the tests for renal artery occlusion?

Vascular studies: A renal artery doppler, mr angiography, IV contrast angiography, co2 angiography, ct angiography are helpful. Older tests include ace inhibitor challenges, searching for drug mediated creatinine rise. This is not much used. ...Read more

What are some alternative treatments for renal artery occlusion?

What are some alternative treatments for renal artery occlusion?

Medications: Occlusion means 100% stenosis. Usually not worth trying to opening due to high failure rate and due to the residual alive part of the kidney already is getting blood from somewhere and whatever died of it has died also risk benefit from bypass surgery is not favorable for same reason. Medications for BP control and conservative management is the way to proceed usually.Also protect the other kidney. ...Read more

Is there a cure for renal artery occlusion?

Is there a cure for renal artery occlusion?

Depends: "occlusion" means 100% blockage. "stenosis" means <100% blockage. If you have abrupt or very recent occlusion or stenosis, the artery can be dilated and stented using a wire & balloon (angioplasty). If there is chronic occlusion, the kidney has been permanently damaged and there's no benefit in doing anything further to the artery. ...Read more

Are there some genetic reasons I could get renal artery occlusion?

Are there some genetic reasons I could get renal artery occlusion?

Yes: There are inherited disorders of clotting that can predispose you to arterial disease in the kidney and elsewhere. Additionally there are familial disorders of metabolism that cause accelerated atherosclerosis. A strong family history of premature arterial disease or heart attacks raises one's suspicions. These conditions can be mitigated through judicious use of medications. ...Read more

Can renal artery occlusion be cured?

Can renal artery occlusion be cured?

Can be relieved: Renal artery occlusion, a chronic condition can usually be relieved rather than "cured". Cure usually suggests that problem has completely resolved. Complete occlusion of renal artery would mean non function of kidney and can not be cured. 25% of people have two renal arteries and second artery can maintain function in part of kidney. Optimal treatment is stent placement by x-ray interventionist. ...Read more

Atrophy: If the vessel is truly totally occluded the kidney will shrink or atrophy. As long as the other kidney is ok, you should be too. See a good nephrologist and endovascular suegeon. ...Read more

How common is it for somebody to get renal artery occlusion?

Not so common: Depends on your age, BP level- less than 1% of patients with moderate or gr 2 ( BP more than 160/100) high blood pressure will have renal artery stenosis or blockage. More common in caucasians than african americans.Usually don't have to screen for ras unless patient is on multiple medications , unable to tolerate medicines, severe high BP requiring hospitalization or kidney function is affected. ...Read more

Are some people more prone to getting renal artery occlusion?

Yes: The most common cause of renal artery stenosis is an obstructing plaque which is due to atherosclerosis. A history of smoking, high cholesterol, high blood pressure and diabetes can cause a blockage to form in these arteries. Another rarer cause is blockage due to thickening within the arterial wall due to inflammation. This tends to occur in women, usually 30-50s, with little or no other risks. ...Read more

I've developed renal artery occlusion. What should I be watching out for in the future?

High blood pressure: If your artery to the kidney is completely blocked, there is no reason to restore flow. However, you should be sure that it is completely blocked, rather than a very tight narrowing, which would require treatment. The artery to your second kidney should be monitored to make sure that there is not an issue there. Losing flow to both kidneys would result in kidney failure, and dialysis. ...Read more

Obstruction (Definition)

Anything that creates a blockage of the intestinal tract. You may think of the intestinal tract (stomach, small bowel, large bowel) as somewhat akin to a garden hose. If you kink the garden hose, or twist it, or block it inside, you have created an "obstruction". Most obstructions are a results of previous surgery and most of these ...Read more
