how is renal artery test done?


it can be done by a dye test where dye is injected into a vein then they use a machine called an isotope scan where you would lay on your back for about 30 minutes while the machine rotates around you this will give a detailed image of your kidneys and the artery's and how they are functioning and working the test is pain free unless you have kidney pain.

hope i helped :)  (+ info)

what is peripheral artery obstruction?


curious
----------

It means an artery away from the most central arteries (aorta and it's major branches) has become occluded with an accumulation of cholesterol particles, scar tissue, calcium and other cellular debris. It does not include the heart. A coronary artery is one of the arteries that supply nourishment for the heart itself. When one of these experiences an obstruction you hae a myocardial infarction (MI) or heart attack. If this obstruction happens anywhere within the brain it is called a cerebral vascular accident (CVA) or stroke.
I put a link to the famous cutting edge research medical center, Mayo Clinic's section on peripheral arterial diseases (PAD). There are several separate disease processes involved that can produce an obstruction in the Peripheral arteries - even the intestines - so use the mayo clinic's search box to find which disease process in particular you are looking for.
Obstructions can be dissolved with IV medications such as TPA or urokinase. The artery where the peripheral blockage occurs can be totally cut out and the artery stitched back together.
You can get partial blockages which causes a good deal of chronic misery in the patients' lives.
It is rather hard to get specific here because I do not know which underlying disease you are referring to. That is why I gave you one link to Mayo clinic and asked you to use the little search box. I hope this helps a little bit

What is the condition for the obstruction of the coronary arteries?


It's a project for medical terminology, and I've looked everywhere and can't find it...please help!
----------

Coronary artery disease is reduced blood flow through the coronary arteries. This is usually due to atherosclerotic plaques, which is usually due to poor diet and aging.

When blood flow is completely obstructed, your heart can't get oxygen and starts to die. You feel a sudden, sharp stabbing pain and yep it's a HEART ATTACK! The med term for heart attack is Myocardial Infarction (infarct = area that dies due to lack of blood; Myocardial = heart muscle).

I'm sure that's what your instructor is looking for. Actually, myocardial infarction is a type of "Acute Coronary Syndrome," which is a phrase doctors use to cover sudden onset chest pain ("unstable angina"), NSTEMI (a type of Myocardial Infarction) and STEMI (a worse type of Myocardial Infarction).  (+ info)

what is renal artery?


The Renal Artery is a branch of the Abdominal Aorta. There are two renal arteries which come off the Aorta. The Renal Arteries supply oxygenated blood to the kidneys.  (+ info)

How can you tell the difference between the renal veins and renal arteries?


question for pig dissection
----------

Renal artery carries oxygenated blood. It is a muscular, thicker structure, compared to the renal vein, which is thinner and carries deoxygenated blood.  (+ info)

The Effect of Narrow Renal Arteries on Urine Production?


I'm doing research for my anatomy & physiology class...

If a child is born with narrow renal arteries, what effect would this have on urine production?

Thanks!

An infant is born with narrowed renal arteries. What effect will this condition have on urine volume?


It depends on the extent of the stenosis. You could have renal agenesis (no urine production) or hypotrophy (possibly decreased) .

If the kidneys are there and functional, and the stenosis is enough to reduce the flow of blood through the kidney, then they will respond as if there was low blood volume in the patient: conserve water. This will happen via various local and systemic changes, ultimately reducing urine output.  (+ info)

From what percentage of obstruction a heart surgery is recomended?


My father has a 40% obstruction on his right coronary and 50% on his left coronary, and a 80% obstruction on his left marginal. With these levels what is the best approach? Heart surgery, angioplasty or other? Detail: although in good health he is 73 yo.
----------

It is not clear from your answer where the 50% on the left coronory was located....
The reason this is important is that disease in the Left Main or 3 vessel disease (L coronory, R coronory, Circumflex) are the 2 clear cut indications for CABG or coronory artery bypass grafting. Mostly of the other blockages are handled and handled well with Angioplasty with or without stents..
Your cardiologist will look at several different things to decide on the treatment approach including collateral blood flow..pump function of the heart etc..
And by the way some of the answers above are ridiculously flawed...if the lesions are such that your cardiologist suggests CABG then that is what he should have.  (+ info)

What will happen in an artery in the leg is clogged up by fatty deposits?


If a coronary artery is clogged, then it leads to heart attack.
If an artery in the brain is clogged, then it leads to a stroke.

But how about in any other places other than these two? Is there any way we can find out whether there are any arteries in our bodies which are clogged up by fats? Any medical check ups etc?
----------

Artherosclerosis in peripheral arteries (such as in the leg) lead to the medical entity known as Peripheral Vascular Disease (PVD).

Gradual reduction in blood flow to the legs will lead to symptoms of intermittent claudication (pain that comes on when you walk a certain distance) due to lack of oxygen supply. More severe blockage may lead to pain at rest, accompanied by pallor of the leg when it is raised.

Sudden acute blockages (think 'heart attack' like) can lead to acute ischaemia - sudden severe pain, pallor, pulselessness - a medical emergency.

PVD is common. Know of any diabetics who have to have parts of their legs chopped of? PVD is definitely a contributing factor in these cases. Less severe cases can be managed with drugs or vascular surgery.

Medical check-ups involve examination of pulses & possibly conducting doppler ultrasound. CT angiograms are sometimes required for a more accurate assessment.  (+ info)

What artery in your neck is the most important?


Is there an artery in your neck that if you get cut across it you can bleed to death in a few minutes? And where is it located?
----------

the carotid artery when severed will result in a very quick death. If you are considering cutting this to commit suicide i strongly recommend against it. People usually end up cutting their windpipe and they suffocate to death or drown on blood. If u get it wrong u will likely have damaged your voice box and be unable to talk for the rest of your life  (+ info)
