Angiogram Side Effects: What You Need to Know

Angiogram side effects are generally mild and temporary, but there’s a small risk of more serious complications. Understanding these risks and what to watch out for can help you better prepare for a procedure and manage any symptoms afterward.

Potential Side Effects of Angiograms

After an angiography procedure, many individuals experience a few common and minor side effects. These typically include:
– Bruising at the site of the incision.
– Soreness around the wound area.
– The presence of a small bump or collection of blood near the incision point.

These minor side effects generally resolve themselves within a few days or weeks. If discomfort persists, over-the-counter pain relievers such as paracetamol can be effective in providing relief.

Minor Complications

In some cases, additional minor complications might occur following an angiogram:
– Infection at the incision site, potentially causing redness, swelling, or pain, which might require antibiotic treatment.
– Mild allergic reactions to the contrast agent used during the procedure, often presenting as an itchy rash. Medication can typically manage these reactions.

Serious Complications

Though the risk is low, some patients may experience more severe complications following an angiogram:
– Kidney damage, particularly in individuals with pre-existing kidney issues, can result from the contrast dye used, but this is usually temporary.
– Heart attack or stroke, though uncommon, are potential risks associated with the procedure.
– Damage to a blood vessel, which may lead to internal bleeding and might require further surgical intervention.
– A serious allergic reaction (anaphylaxis) to the contrast agent, possibly causing dizziness, breathing difficulties, or even loss of consciousness.
– Formation of blood clots, which could threaten a limb or result in other issues.
– Tissue damage from X-ray radiation, particularly if the procedure is prolonged.
– Abnormal heart rhythms (arrhythmias).
– Death, an extremely rare outcome with a risk of less than 1 in 1,000.

The risk of these serious complications is very low, and procedures are typically recommended when the benefits outweigh these risks. Those with existing heart or kidney problems may have a higher risk of complications.

When to Seek Medical Help

It’s crucial to seek medical attention if you experience any of the following symptoms after an angiography:
– Bleeding from the wound that doesn’t stop after applying pressure.
– Severe pain that doesn’t subside.
– Redness, swelling, or heightened warmth at the incision site.
– Changes in color or temperature of the limb used for accessing the blood vessel.
– Development of a firm, tender lump or discharge at the incision site.

If you’re experiencing any persistent or concerning symptoms following your angiogram, contacting your healthcare provider promptly is advisable.

For more detailed information, you can refer to the NHS’s risks related to angiography or their guide on cardiac catheterisation and coronary angiography risks.

Understanding and being aware of these potential side effects and complications not only aids in preparation but also ensures a quicker response if you experience any unusual symptoms.
