Angiogram Procedure: Purpose, Risks, and Recovery

As a vascular surgeon, I often meet patients who suffer from vague symptoms—unexplained leg pain, fatigue during walking, or sudden chest discomfort. Many of them have undergone basic tests like an ECG or ultrasound, but the cause remains elusive. That’s when an angiogram helps us get definitive answers.

An angiogram is not just another test. It allows us to see your blood vessels in real time, identify blockages or narrowings, and decide the best course of treatment. Whether the concern is heart-related, brain circulation, leg arteries, or kidney vessels, this procedure gives us crucial insights.

In this blog, I will explain what an angiogram is, its purpose, the different types, what to expect during the procedure, risks involved, cost considerations in India, and what recovery looks like. This guide is especially helpful if you or a loved one is advised to undergo this test.

What Is an Angiogram?

An angiogram, also referred to as an angiography test, is a specialized diagnostic procedure used to visualize blood vessels using X-ray imaging. It involves injecting a contrast dye into the bloodstream, allowing clear images of the arteries and veins to be captured.

This test helps detect narrowed or blocked arteries, aneurysms, blood clots, or vascular malformations. It is commonly used to diagnose conditions affecting the heart, brain, lungs, kidneys, and limbs.

Purpose of the Angiogram Procedure

The primary goal of an angiogram is to evaluate blood flow in the body. It helps diagnose and assess:

• Blocked or narrowed arteries due to plaque buildup
  
• Peripheral arterial disease (PAD)
  
• Aneurysms or vascular malformations
  
• Blood clots
  
• Pulmonary embolism
  
• Stroke risk in patients with transient symptoms
  
• Post-surgical graft monitoring
  

In patients with unexplained symptoms or in those with a high risk of vascular disease, angiograms play a vital role in guiding further treatment.

Types of Angiogram

There are several types of angiograms, each designed to examine a specific part of the body:

• Coronary Angiogram
  Used to assess blood flow to the heart and identify blockages in coronary arteries.
• Cerebral Angiogram
  Examines blood vessels in the brain and is used for stroke evaluation or aneurysm detection.
• Pulmonary Angiogram
  Evaluates blood flow to the lungs and helps diagnose pulmonary embolism.
• Peripheral Angiogram
  Checks arteries in the arms or legs, often used in patients with leg pain or non-healing wounds.
• Renal Angiogram
  Used to examine arteries supplying the kidneys, especially in patients with resistant hypertension.

Each of these types follows a similar basic procedure but targets different anatomical regions depending on the clinical concern.

What to Expect During the Procedure

The angiogram is usually performed in a specialized lab called a catheterization laboratory or cath lab. Here’s what typically happens:

• You will lie on an examination table and be connected to monitors.
  
• A local anesthetic is applied to numb the area, commonly the groin or wrist.
• A needle puncture is made into the artery & a sheath is placed.
  
• A small catheter is inserted through the sheath and negotiated up to the area to be seen.
  
• Contrast dye is gently injected through the catheter.
  
• Real-time X-ray images are taken to track the flow of blood.
  

The procedure usually takes between 30 minutes and one hour. In most cases, you will remain awake and may feel a warm sensation when the dye is injected. After the test, you will need to lie flat for a few hours to avoid bleeding from the puncture site. The puncture site is pressed for 20 to 30 minutes, and a tight belt or heavy weight is applied to prevent bleeding. 

Risks of Angiogram

Although angiograms are generally safe, they are not entirely without risks. These risks are usually minimal when the procedure is performed by an experienced vascular specialist in a well-equipped center.

Some potential complications include:

• Bleeding or bruising at the catheter insertion site
  
• Allergic reaction to the contrast dye
  
• Irregular heartbeat or dizziness
  
• Kidney stress or damage due to the dye
  
• Infection (rare)
  
• Stroke or heart attack (extremely rare)
  

The risk of angiography in elderly patients may be slightly higher, particularly if they have underlying kidney disease or poor general health. Careful evaluation and preparation help minimize these risks.

Angiography Procedure Cost in India

The cost of angiography in India can vary depending on the city and hospital, and whether the test is done as an outpatient or inpatient procedure. On average, the cost ranges from ₹15,000 to ₹35,000. In larger metro cities or in hospitals that offer advanced imaging technology, the price may go up to ₹60,000.

This cost typically includes the procedure, catheter use, contrast dye, and monitoring. Additional tests or hospital stay may incur extra charges. Compared to Western countries, the angiography procedure cost in India remains significantly more affordable.

Angiogram Recovery: What Patients Should Know

Recovery after an angiogram is usually straightforward. Most patients are able to return home the same day or after an overnight stay. Here’s what to keep in mind during the recovery phase:

• Avoid strenuous activities for 24 to 48 hours
  
• Drink plenty of fluids to flush out the contrast dye.
  
• Monitor for any swelling or bleeding at the catheter site.
  
• Follow all instructions provided by your vascular surgeon.
  

Mild soreness or bruising at the insertion site is common. Full recovery is expected within a few days. If you experience chest pain, dizziness, or unusual swelling, you should seek medical advice immediately.
