Angiography is a vital diagnostic procedure used to visualize the blood vessels and identify any blockages, narrowing, or abnormalities. It is commonly performed to assess heart conditions, peripheral artery disease, or cerebrovascular issues. For patients preparing for an angiography, understanding the procedure and what happens afterward can help reduce anxiety and ensure a smoother experience. This article provides a detailed overview of what to expect during and after your angiography procedure.
What Happens Before the Procedure?
Before undergoing angiography, you will be required to undergo some preparations:
- Pre-procedure Assessment: Your doctor will evaluate your medical history, current medications, and any allergies, especially to iodine-based contrast dye. Blood tests may also be performed to assess kidney function and clotting ability.
- Fasting: You may be asked to avoid eating or drinking for 6-8 hours before the procedure.
- Medication Adjustments: Your doctor may instruct you to stop certain medications, such as blood thinners, before the procedure.

What to Expect During the Procedure
- Arrival and Preparation:
- Upon arrival, you will change into a hospital gown, and a small area of your body, typically the groin or wrist, will be shaved and cleaned.
- An intravenous (IV) line may be inserted into your arm for administering medications.
- Sedation and Local Anesthesia:
- You’ll remain awake during the procedure but may receive mild sedation to help you relax.
- Local anesthesia will be applied to numb the area where the catheter will be inserted.
- Catheter Insertion:
- A thin, flexible tube (catheter) is inserted into a blood vessel, usually in the groin or wrist.
- The catheter is guided through the blood vessels to the area being examined, such as the coronary arteries or brain.
- Contrast Dye Injection:
- A special contrast dye is injected through the catheter. This dye makes blood vessels visible on X-rays or imaging scans.
- You may feel a warm or flushing sensation when the dye is injected, but this is normal and temporary.
- Imaging and Examination:
- The doctor will capture a series of X-ray images to assess blood flow and identify any blockages or abnormalities.
- The procedure typically lasts 30-60 minutes, depending on the complexity of the case.

What to Expect After the Procedure
- Post-procedure Monitoring:
- After the procedure, you will be moved to a recovery area for observation.
- The insertion site will be monitored for bleeding or swelling, and your vital signs will be regularly checked.
- Pressure Application:
- Pressure may be applied to the insertion site to prevent bleeding. If the catheter was inserted in the groin, you may need to lie flat for a few hours to minimize the risk of bleeding.
- Hydration and Rest:
- You’ll be encouraged to drink fluids to flush the contrast dye from your system.
- Rest is essential, and strenuous activities should be avoided for at least 24-48 hours.
- Possible Side Effects:
- Mild bruising, soreness, or discomfort at the catheter insertion site is common and usually resolves in a few days.
- If you experience excessive bleeding, swelling, or signs of infection, such as redness or fever, contact your doctor immediately.

When Can You Resume Normal Activities?
- Most patients can resume light activities within a day or two after the procedure.
- Your doctor will provide specific instructions based on your condition and the findings of the angiography.
Follow-up and Next Steps
After the angiography, your doctor will discuss the results with you and outline the next steps. If blockages or abnormalities were detected, additional treatments such as angioplasty, stent placement, or medications may be recommended.
