What is Angiography?

Angiography, also known as an arteriogram, is a diagnostic imaging procedure used to visualize the blood vessels in the body. This test helps detect blockages, narrowing, or abnormalities in arteries or veins and provides crucial information for diagnosing and managing vascular conditions.

Using advanced imaging techniques, such as X-rays, CT scans, or MRIs, angiography allows doctors to assess blood flow and plan appropriate treatments.

Why is Angiography Performed?

Angiography is used to diagnose and evaluate conditions affecting blood vessels, including:

• Coronary artery disease (CAD): Blockages in the arteries supplying blood to the heart.
• Peripheral arterial disease (PAD): Narrowing of blood vessels in the arms or legs.
• Aneurysms: Bulging or weakened areas in blood vessels.
• Deep vein thrombosis (DVT): Blood clots in the veins.
• Pulmonary embolism: Blockage in the arteries of the lungs.
• Stroke or TIA (mini-stroke): To identify blood flow issues in the brain.

Types of Angiography

There are several types of angiography, depending on the area being examined:

1. Coronary Angiography: Evaluates blood flow in the coronary arteries of the heart.
2. Cerebral Angiography: Focuses on blood vessels in the brain.
3. Peripheral Angiography: Examines blood flow in the arms, legs, and pelvis.
4. Pulmonary Angiography: Assesses blood vessels in the lungs.
5. Renal Angiography: Checks blood flow to the kidneys.

How is Angiography Performed?

Angiography is a minimally invasive procedure that involves the following steps:

1. Preparation:
   • The patient may need to fast for a few hours before the procedure.
   • A mild sedative might be administered to help relax.
2. Catheter Insertion:
   • A small incision is made, usually in the groin or wrist.
   • A thin, flexible tube (catheter) is inserted into a blood vessel and guided to the area of interest.
3. Contrast Dye Injection:
   • A special contrast dye is injected through the catheter.
   • This dye highlights blood vessels on the imaging equipment.
4. Imaging:
   • X-rays, CT, or MRI captures detailed images of the blood vessels.
5. Completion:
   • Once images are taken, the catheter is removed, and pressure is applied to stop bleeding.
   • The procedure typically lasts 30–60 minutes.

Benefits of Angiography

• Accurate Diagnosis: Provides precise information about blood flow and vessel condition.
• Guides Treatment: Helps doctors determine the need for further procedures, such as angioplasty or bypass surgery.
• Minimally Invasive: Requires only a small incision and short recovery time.
• Early Detection: Identifies vascular issues before they cause serious complications like heart attacks or strokes.

Risks and Safety of Angiography

Angiography is generally safe, but like any medical procedure, it carries some risks:

• Minor bleeding or bruising at the catheter site.
• Allergic reaction to the contrast dye.
• Rare complications, such as infection, blood vessel damage, or kidney issues.

To minimize risks, angiography is performed by experienced specialists in a controlled environment.

After the Procedure

1. Monitoring: Patients are observed for a few hours to ensure there are no complications.
2. Activity Restrictions: Avoid strenuous activities for a day or two.
3. Hydration: Drink plenty of fluids to help flush out the contrast dye.
4. Follow-Up Care: Your doctor will discuss the results and recommend further treatment if needed.

Who Should Consider Angiography?

Angiography is recommended if you experience symptoms such as:

• Chest pain or shortness of breath.
• Leg pain or numbness during walking.
• Persistent headaches or dizziness.
• High blood pressure that doesn’t respond to treatment.
