Preparing for Your Angiography: Tips and Information

Here is the basic preparation before, during, and after Angiography for any patient.


Before Angiography:

  • Consultation: Schedule the angiography procedure and discuss your medical history, allergies, and any concerns with your healthcare provider.
  • Fasting: Follow fasting instructions provided by your healthcare team, often requiring you to avoid food and liquids for a specific duration before the procedure.
  • Medications: Inform your healthcare provider about all medications you are taking. Some may need to be adjusted or temporarily stopped, especially blood-thinning medications.
  • Allergies: If you have known allergies to contrast dye or iodine, communicate this to your healthcare provider beforehand.
  • Clothing: Wear comfortable clothing and avoid jewelry or accessories. You may be asked to change into a hospital gown.


During Angiography:

  • Preparation: You'll be positioned on the angiography table, and the area where the catheter will be inserted (often in the groin or wrist) will be cleaned and numbed.
  • Contrast Dye: Contrast dye is injected through the catheter to make blood vessels visible on X-ray images. You may feel a warm sensation when the dye is injected.
  • Monitoring: Vital signs will be monitored throughout the procedure, and you may be asked to report any sensations or discomfort.
  • Remain Still: It's crucial to stay as still as possible during the procedure to obtain clear images.


After Angiography:

  • Recovery: After the procedure, you'll be monitored for a few hours. Rest and avoid strenuous activities for the remainder of the day.
  • Hydration: Drinking fluids can help flush the contrast dye from your system. Follow any hydration recommendations from your healthcare team.
  • Results: Your angiography results will be reviewed by a specialist, and a report will be sent to your healthcare provider.
  • Follow-Up: Schedule a follow-up appointment with your healthcare provider to discuss the angiography results and any further steps or treatments if needed.

Note that specific instructions and procedures may vary depending on the type of angiography and your individual medical condition. Always follow the guidance provided by your healthcare team for a successful and safe angiography procedure.

Angiography Procedure

The procedure for Angiography typically follows these steps:

  • Check-in and registration at the angiography department.
  • You'll change into a hospital gown and remove any jewelry or metal objects.
  • An intravenous (IV) line may be inserted to provide medications and fluids.
  • You'll lie on an examination table, usually flat on your back.
  • Sterile drapes are used to maintain a sterile field around the area of interest.
  • Local anesthesia is applied to numb the insertion site, often in the groin or wrist.
  • A catheter (thin, flexible tube) is inserted into an artery through a small incision.
  • Contrast dye is injected through the catheter to visualize blood vessels on X-ray.
  • Continuous X-ray images are taken as the dye flows through the blood vessels.
  • The procedure may involve different angles and positions.
  • You may be asked to hold your breath or make specific movements.
  • The duration of the procedure varies but typically takes 30 minutes to a few hours.
  • After the procedure, the catheter is removed, and pressure is applied to the insertion site to prevent bleeding.
  • You'll be monitored for a short time before discharge.
  • The images are interpreted by an interventional radiologist or vascular surgeon.
  • You may receive the results during your visit or at a later time.


Angiography Results

Here are some common elements you might find in a Angiography report:

Angiography Findings Interpretation
Blood Vessels Examined Normal or Abnormal
Specific Vessel Observations Description of any abnormalities, such as blockages, stenosis, aneurysms, or vascular malformations
Blood Flow Assessment Evaluation of blood flow, velocity, and direction
Use of Contrast Material Details about the use of contrast agents, if applicable
Impression Summary of key findings or diagnostic impressions
Recommendations Follow-up tests, treatments, or interventions, if necessary
Conclusion Final remarks or clinical recommendations

Angiography is a dynamic imaging technique used to visualize blood vessels, and the results are typically discussed with the healthcare provider during or immediately after the procedure. Any abnormal findings would be addressed promptly, and appropriate next steps would be determined based on the clinical context.


Angiography Abnormal Results

Here is potential causes of abnormal angiography results:

Abnormal Angiography Finding Potential Causes
Vascular Narrowing (Stenosis) Atherosclerosis, plaque buildup, vasculitis
Blocked Blood Vessel Thrombosis, embolism, arterial dissection
Aneurysm Weakening of the blood vessel wall, congenital abnormalities
Vascular Malformation Congenital malformations, arteriovenous malformations
Abnormal Blood Flow Vascular obstruction, shunts, collateral vessels
Contrast Extravasation Vascular injury, rupture, or leakage

Abnormal angiography findings can have various causes, and further evaluation and management depend on the specific findings and the patient's clinical condition. These results are typically interpreted by a vascular specialist or interventional radiologist who can determine the appropriate course of action.


How Long Does an Angiography Take?

The duration of an angiography procedure can vary depending on the specific type of angiography and the complexity of the examination. Here's a general overview of the approximate time it takes for different types of angiography procedures:

Angiography Procedure Duration
Diagnostic Angiography 30 minutes to 1 hour
Coronary Angiography 30 minutes to 1 hour
Cerebral Angiography 1-2 hours
Peripheral Angiography 30 minutes to 1 hour
Pulmonary Angiography 30 minutes to 1 hour
Renal Angiography 30 minutes to 1 hour
Aortic Angiography 30 minutes to 1 hour
Cardiac Catheterization 1-2 hours (including angiography)
  • Please note that these are approximate times and can vary based on factors such as the complexity of the blood vessel network being examined, the patient's specific condition, and the need for additional procedures during angiography.
  • Additionally, some angiography procedures may require sedation or anesthesia, which can extend the total procedure time.
  • Always follow the guidance provided by your healthcare provider for your specific angiography procedure.

Angiography FAQ

What is Angiography?

Angiography is a medical procedure that uses X-rays and contrast dye to visualize blood vessels in the body. It helps diagnose and treat conditions like blockages, aneurysms, or narrowing of arteries.

Why is Angiography done?

Angiography is performed to detect and evaluate vascular problems, assess coronary artery disease, plan interventions, or monitor the progress of treatment. It's essential for diagnosing heart conditions, stroke risk, and peripheral artery disease.

How is Angiography performed?

During angiography, a catheter is inserted into an artery, contrast dye is injected, and X-rays are taken. The dye highlights blood vessels, allowing the doctor to examine them on a monitor. It can be done in various areas of the body, like the heart (coronary angiography) or brain (cerebral angiography).

Can I eat before Angiography?

Typically, patients are advised not to eat or drink for a few hours before angiography. Your healthcare provider will provide specific fasting instructions before the procedure.
