Angiogram of renal arteries
Common Questions and Answers about Angiogram of renal arteries
angiogram
I read that it can affect any 
A family member found out she had fibromuscular dysplasia (FMD) and suggested I be checked out for that as well since this came out of the blue. I had another renal just recently, and it showed 80% blockage (I couldn't have an angiogram because I'm allergic to the dye and prednisone), which could be atherosclerotic (no way of telling without the angiogram; I did have an MRA with gadolinium, but they couldn't be sure of what they saw due to poor imaging).
Different people have different layouts of coronary arteries. Sounds strange I know, but there are different groups people are put into, depending which of their arteries are dominant or co-dominant or non-dominant. I for example am Co-dominant where the left and right arteries share equal amounts of the heart, supplying it with oxygen. Some are left dominant where the LAD and LCX supply most of the back of the heart. Some are right dominant where the RCA does this job.
It is important to note that calcification of the coronary arteries is part of the aging process, and all people develop calcium with age. For example, one study looked at calcium scores and coronary arteries using angiography. Almost all patients (95%) less than 40 years old with calcium score of less than 8 had no significant narrowing of the arteries. In patients over 70 years old, this number was much higher.
The first letter of the main coronary arteries designate whether left or right. Such as LCX left circumflex LAD left anterior descending RCA right coronary artery. It would be better to look at a diagram rather than explain it, here's an example for you....

If there are blockages, a stent implant (usually done at time of angiogram) will increase the diameter of the occlusion/occlusions permitting more blood to the deficit area. Sometimes the area of blockage can not be stented because of location, tortuous segment, too long, etc...then a bypass surgical operation may be the only remedy.
Alternatively, some people find relief from chest pain with medication.
berlysue,
The doctors are concerned that parts of your heart may not be getting enough blood. The doctors will be performing an angiogram to look to see if you have blockages in your coronary arteries (the arteries which supply blood to the heart) which are the cause of your slightly low ejection fraction and wall motion abnormality (which means that part of your heart isn't beating a vigorously as your would like).
Yes, a CT scan 64-slice angiogram is an alternative to the intervention of a cath angiogram. Because there has been too many unnecessary stent implants, there are quidelines for treatment of angina and suspected CAD.
If angina (chest pain) can be controlled with medication, then treat medically. If angina is not controlled, then stent occlusions greater than 70%. In the event there is an emergency with an occlusion then a by pass.
ve finally found a problem as a result of paying for a CT Coronary Angiogram. All I know right now is that I have a narrowing of the left main artery but I don't know the extent or the cause. I am now waiting to have a standard angiogram but I am supposed to be flying to the US from the UK in 3 weeks. Has anyone flown soon after an angiogram? How about after a stent? Appreciate your thoughts.
s amazing how many people are being given calcium supplements for bone deficiencies to find most of it is being deposited in the arteries. I believe they feel certain types of calcium work better than others (obviously more expensive) but other minerals are also required before it will be used in bone. People have to make a choice between healthy bones and calcified arteries, or neither.
An Angiogram definitely doesn't see arteries like arterioles, they are the thickness of a hair. I believe it takes a special type of MRI to look at these vessels.
Given my other results, should I have gone directly to the more conventional angiogram in spite of the slightly greater risk? If there is a good chance that I will need an angiogram anyway, am I not putting myself at risk by going through another step? Is there a good publication for lay people that I can read that might shed more light on this question?
The link to ANGIOGRAM at the bottom of your post gives a doctor's information about an angiogram with a cath (intervention) that is threaded through a vessel to your heart. Takes about an hour and a surgical doctor will be on standby in the event there is a puncture, etc. My complaint is an interventional cardiologists is inclined to implant stents during the procedure.
