An interventional radiologist performs the angiogram. During the procedure, the interventional radiologist places a catheter or small tube into one of your arteries and injects contrast material commonly called "dye" into vessel while taking x-rays of the area. The angiogram takes about one to two hours to finish.
Sometimes, it may take longer. In other cases, the interventional radiologist will do a second procedure, such as an angioplasty, at the same time as the angiogram. This makes the procedure take longer. You will be given intravenous sedation. The interventional radiologist will clean the area where the catheter will be inserted.
This area is at the top of the leg or rarely on the upper arm. The doctor will then put a local anesthetic in the skin. The catheter is inserted into the artery in the numbed area. The catheter is then guided through the body to the artery that is being studied by watching it on an x-ray screen similar to a TV screen. You will not feel the catheter moving through your arteries. When the catheter is positioned correctly, contrast x-ray dye will be injected through the catheter while X-ray pictures are taken.
When the contrast is injected, you may feel warm this lasts for only a few seconds. In many cases, several contrast injections and several sets of X-rays are needed to complete an examination.
After the examination is completed, the interventional radiologist will remove the catheter from the artery. X-rays will be used to look at your heart. The contrast dye will outline your arteries and show if there are any blockages. While most people do not feel the dye injection, some feel minor discomfort in their chest, lightheadedness, or nausea.
Or, if the angiogram shows serious blockages, your interventional cardiologist may immediately perform balloon angioplasty and stenting to open the blockage and restore blood flow to your heart, or you may be referred to a heart surgeon for a bypass operation.
When the procedure is complete, the catheter is removed and the doctor may use a device to seal the artery puncture site.
Otherwise, the doctor or nurse applies pressure to the puncture site and holds it for about 20 minutes. If the catheter was inserted in your leg, you may need to lie still for two to six hours after the catheter is removed. After you return to your home, you may notice a bruise in the area where the doctor inserted the catheter.
It is not necessary to report bruising to your doctor, even if the area is large. Usually, it clears up over a period of one to three weeks. You should call the doctor or nurse practitioner if you have:. However, there are risks with any test. Bleeding, infection, and irregular heartbeat can occur. More serious complications, such as heart attack , stroke , and death can occur, but they are uncommon.
If you are allergic to iodine or x-ray dye, notify your physician or nurse practitioner so that medication to avoid an allergic reaction can be prescribed. Be sure your doctor knows all the medications you are taking. Generally, you should continue your medications, but you doctor may ask you to hold a blood thinner, diuretic, or other medication.
Ask them. If you do have a stent put in angioplasty during your angiography, it will take a bit longer. You may need to stay in hospital for several hours or overnight following the procedure.
You may be asked to drink fluids to prevent dehydration and flush the dye from your kidneys. Before going home, a nurse will teach you how to check the site for bleeding and explain what to do if this does happen. If the groin was the site used, you may be asked to avoid heavy lifting and straining for a week to prevent bleeding. As with all medical procedures, there are both risks and benefits associated with having a coronary angiography and angioplasty.
Talk to your doctor, nurse and other health professional about the risks and benefits for you, and any concerns you may have. Allergy testing is used to find which substances provoke an allergic reaction. Aortic stenosis may be congenital present from before birth , but is often diagnosed during teenage years. Barium tests are used to examine conditions of the digestive tract such as reflux, narrowing or ulceration.
Before a biopsy, you need to discuss a range of issues with your doctor or surgeon. Pathology tests cover blood tests, and tests on urine, stools faeces and bodily tissues. Content on this website is provided for information purposes only.
