Dr. Ania Kielar, vice-president of the Canadian Association of Radiologists and vice-chair of the University of Toronto\u2019s department of medical imaging, explains everything patients need to know about angiograms<\/em><\/p>\n

What is an angiogram?<\/strong>
\nAn angiogram encompasses a series of diagnostic tests that use X-rays and a contrasting agent, or dye, to generate images of the body\u2019s blood vessels. During the procedure, a long tube called a catheter may be inserted into an artery \u2014 usually in the arm, groin or neck \u2014 and threaded through blood vessels to help diagnose any issues. \u201cThey are usually done by interventional radiologists, which are radiologists who perform more procedures,\u201d says Dr. Kielar. \u201cYou go into a room that looks a little like an operating room but it\u2019s got a very fancy machine that moves around you. They may be able to fix things on the spot but they are basically looking at your blood vessels.\u201d<\/p>\n

What is a contrast agent?<\/strong>
\nA contrast agent, or dye, is required for a coronary angiogram \u2014 the most common form of angiogram \u2014 to make blood vessels more visible to X-rays. Patients may be required to have a blood test prior to the procedure to ensure they are not allergic to the agent and that their blood is able to clot properly.<\/p>\n

What does an angiogram show?<\/strong>
\nAngiograms are extremely useful for detecting the source of abnormalities in blood vessels, including any narrowing or blockages of the body\u2019s arteries. They can help diagnose a wide range of issues, including heart disease, stroke (or the risk of stroke), kidney and liver issues and many forms of vascular disease. \u201cThey can try to open up a vessel if its closed or they can put in wires, tubes or stents,\u201d Dr. Kielar says. \u201cIt really just depends on what the issue is.\u201d<\/p>\n

How long does an angiogram take?<\/strong>
\nGenerally between 30 minutes and two hours. \u201cIt just depends on what they\u2019re doing,\u201d Dr. Kielar says.<\/p>\n

How can patients prepare for an angiogram?<\/strong>
\nClothing\/jewelry<\/em> \u2014 Patients will be required to change into a gown before the procedure but angiograms can be invasive tests, so it\u2019s best to have loose-fitting, comfortable clothing to change into afterwards. Jewelry and other valuables should be left at home.
\nDietary requirements<\/em> \u2014 \u201cYou will probably be asked not to eat for a few hours beforehand if not the night before,\u201d Dr. Kielar says. \u201cThey\u2019ll give specific instructions but it really depends on the procedure.\u201d
\nBloodwork<\/em> \u2014 Blood tests may be required before the procedure to ensure a patient does not have an allergy to the contrast agent and that their blood has the ability to properly clot.
\nMedications<\/em> \u2014 Be sure to follow your doctor\u2019s instructions prior to an angiogram as some medications must not be taken before certain procedures.
\nSupport<\/em> \u2014 Patients should arrange to have someone take them to and from their appointment.<\/p>\n

Is there anything patients should do after an angiogram?<\/strong>
\nPatients will typically be monitored for a few hours following the procedure and given instructions to take home with them. They should avoid any strenuous activity after their angiogram and drink plenty of water to help clear the contrast agent from their system.<\/p>\n

How long does it take for results to come back?<\/strong>
\nResults generally take a few days \u2014 around the same amount of time as a CT scan or an MRI, according to Dr. Kielar. \u201cWe do the procedure, we write the report and we sign off, usually by the end of the day but it can take a couple of days depending on what\u2019s happening. Then the doctor will get it a day or two later. A lot of patients can now read their own reports online. You just have to remember as a patient that it\u2019s going to be written in medicalese.\u201d<\/p>\n

Are there any other concerns or risks that accompany an angiogram?<\/strong>
\nAny procedure performed this close to the heart or brain has some level of risk but major issues are rare and will be discussed with patients ahead of time. Potential complications include stroke, heart attack, kidney damage, infection and excessive bleeding. \u201cGenerally speaking, nothing that we do is particularly high risk but I think people at least need to know what they\u2019re getting into,\u201d Dr. Kielar says. \u201cFor example, if you\u2019re having something done in your brain, for an aneurism, they may intubate you like they would for a regular surgery. Whereas for most other things, it\u2019s almost nothing.\u201d<\/p>\n

How has the pandemic changed the way angiograms are performed?<\/strong>
\nLike all scans performed by a radiologist, wait times for an angiogram have generally gone from bad to worse, Dr. Kielar says. Interventional radiologists \u2014 the professionals who conduct angiograms \u2014 have been particularly busy over the past two years. \u201cThese guys have probably had the most work required because they also put in chest tubes and pick lines and a lot of people who have COVID need a lot of long-term medication. They have been doing a ton of work for a very long time during COVID.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
