Renal Angiography/Angioplasty
What is coronary angiography used for?
Your doctor uses the angiogram to check for blocked or narrowed blood vessels in your heart. A coronary angiogram is a procedure that uses X-ray imaging to see your heart’s blood vessels. The test is generally done to see if there’s a restriction in blood flow going to the heart.
Which dye is used in coronary angiography?
Coronary angiography is a procedure that uses contrast dye, usually containing iodine, and x ray pictures to detect blockages in the coronary arteries that are caused by plaque buildup.
What is angiography report?
Angiography is an imaging test that uses X-rays to view your body’s blood vessels. The X-rays provided by an angiography are called angiograms. This test is used to study narrow, blocked, enlarged, or malformed arteries or veins in many parts of your body, including your brain, heart, abdomen, and legs.
What is a coronary angiography?
A coronary angiography is a test to find out if you have a blockage in a coronary artery. Your doctor will be concerned that you’re at risk of a heart attack if you have unstable angina, atypical chest pain, aortic stenosis, or unexplained heart failure.
During the coronary angiography, a contrast dye will be injected into your arteries through a catheter (thin, plastic tube), while your doctor watches how blood flows through your heart on an X-ray screen.
Preparing for a coronary angiography
Doctors often use an MRI or a CT scan before a coronary angiography test, in an effort to pinpoint problems with your heart.
Don’t eat or drink anything for eight hours before the angiography. Arrange for someone to give you a ride home. You should also have someone stay with you the night after your test because you may feel dizzy or light-headed for the first 24 hours after the cardiac angiography.
In many cases, you’ll be asked to check into the hospital the morning of the test, and you’ll be able to check out later the same day.
At the hospital, you’ll be asked to wear a hospital gown and to sign consent forms. The nurses will take your blood pressure, start an intravenous line and, if you have diabetes, check your blood sugar. You may also have to undergo a blood test and an electrocardiogram.
Let your doctor know if you’re allergic to seafood, if you’ve had a bad reaction to contrast dye in the past, if you’re taking sildenafil (Viagra), or if you might be pregnant.
What happens during the test
Before the test, you’ll be given a mild sedative to help you relax. You’ll be awake throughout the test.
Your doctor will clean and numb an area of your body in the groin or arm with an anesthetic. You may feel a dull pressure as a sheath is inserted into an artery. A thin tube called a catheter will be guided gently up to an artery in your heart. Your doctor will supervise the whole process on a screen.It’s unlikely that you’ll feel the tube move through your blood vessels.
How the test will feel
A slight burning or “flushing” sensation can be felt after the dye is injected.
After the test, pressure will be applied at the site where the catheter is removed to prevent bleeding. If the catheter is placed in your groin, you may be asked to lie flat on your back for a few hours after the test to prevent bleeding. This can cause mild back discomfort.
Drink plenty of water after the test to help your kidneys flush out the contrast dye.
Understanding the results of a coronary angiography
The results show whether there is a normal supply of blood to your heart and any blockages. An abnormal result may mean that you have one or more blocked arteries. If you have a blocked artery, your doctor may choose to do an angioplasty during the angiography and possibly insert an intracoronary stent to immediately improve blood flow.
Risks associated with getting a coronary angiography
Risks can include:
- bleeding or bruising
- blood clots
- injury to the artery or vein
- a small risk of stroke
- a very small chance of a heart attack or a need for bypass surgery
- low blood pressure
Recovery and follow-up when you get home
Relax and drink plenty of water. Don’t smoke or drink alcohol.
Because you’ve had an anesthetic, you shouldn’t drive, operate machinery, or make any important decisions immediately.
Remove the bandage after 24 hours. If there’s minor oozing, apply a fresh bandage for another 12 hours.
For two days, don’t have sex or perform any heavy exercise.
Don’t take a bath, use a hot tub, or use a pool for at least three days. You may shower.
Don’t apply lotion near the puncture site for three days.
You’ll need to see your heart doctor a week after the test.
What is heart angioplasty and stent placement?
Angioplasty and stent placement are common procedures to open arteries in the heart that are clogged. These procedures are formally known as coronary angioplasty or percutaneous coronary intervention.
Angioplasty involves the use of a tiny balloon to widen the artery. A stent is a tiny wire-mesh tube that your doctor inserts into the artery. The stent stays in place to prevent the artery from closing. A cardiologist typically performs both procedures at the same time.
Why do I need heart angioplasty and stent placement?
The procedure is commonly done when a fatty substance known as plaque attaches to the walls of an artery. This is a condition known as atherosclerosis. The buildup of plaque causes the inside of the artery to narrow, restricting blood flow.
When plaque affects the coronary arteries, it’s known as coronary heart disease — a serious health condition. The buildup of plaque in the arteries is particularly threatening to your health because the coronary arteries supply the heart with fresh, oxygenated blood. Without it, the heart can’t function.
Angioplasty and stent placement can alleviate the blockage of an artery and angina, orpersistent chest pain, that medications can’t control. They’re also emergency procedures used if someone is having a heart attack.
Angioplasty and stents can’t help some conditions. For example, coronary artery bypass surgery could be a better option when the main artery on the left side of the heart experiences a blockage. A doctor might also consider coronary bypass surgery if the patient suffered blockages in multiple arteries or has diabetes.
