Stent Or Bypass Surgery To Treat Blocked Arteries?

When it comes to treating blocked arteries, two of the most common procedures are stenting and bypass surgery. Both are effective in restoring blood flow to the heart, but they are used in different situations. If you or a loved one is facing this decision, understanding the differences between a stent or bypass can help you make an informed choice. This article explains what these procedures involve, and when they are recommended.

What Is A Stent?

A stent is a small, mesh-like tube used to open up narrowed or blocked arteries. The procedure to insert a stent is called angioplasty. Here’s how it works:

• A thin tube (catheter) with a balloon at its tip is inserted into the blocked artery.
• The balloon is inflated to widen the artery, and the stent is placed to keep it open.
• This improves blood flow to the heart and relieves symptoms like chest pain (angina).

When Is A Stent Used?

• For patients with one or two blocked arteries.
• When the blockage is not too severe or complex.
• As a minimally invasive option for those who prefer a quicker recovery.

Cost In Singapore: In private hospitals, angioplasty with stenting typically costs between S$15,000 and S$30,000, depending on the type of stent and the complexity of the procedure. MOH’s benchmark recommended costing (TOSP Code: SD720A ; accessed Jan 2025) for surgeon fees is S$6,700 – S$11,200.

What Is Bypass Surgery?

Bypass surgery, or Coronary Artery Bypass Grafting (CABG), is a more invasive procedure. It involves creating a new pathway for blood to flow around the blocked artery. Here’s what happens:

• A surgeon takes a healthy blood vessel from another part of the body (usually the leg, arm, or chest).
• This vessel is then attached to the blocked artery, bypassing the blockage and restoring blood flow to the heart.

When Is Bypass Surgery Used?

• For patients with multiple or severe blockages.
• When the left main coronary artery is blocked.
• If stenting is not a viable option due to the complexity of the blockage.

Cost In Singapore: In private healthcare, bypass surgery can cost between S$30,000 and S$50,000, depending on the number of bypasses needed and the patient’s overall health. MOH’s recommended benchmark costing (TOSP Code: SD813H) for surgeon fees is S$24,400 – S$35,500.

Stent Or Bypass: Which Is Better?

The choice between a stent or bypass depends on several factors, including:

1. Severity Of Blockages: Stents are suitable for simpler blockages, while bypass surgery is better for multiple or complex blockages.
2. Patient’s Health: Older patients or those with other health conditions may not be suitable for bypass surgery due to its invasiveness.
3. Recovery Time: Stenting is less invasive, with a recovery time of a few days. Bypass surgery requires a longer recovery period, often several weeks.
4. Long-Term Outcomes: Bypass surgery may offer better long-term results for patients with severe coronary artery disease.

Making The Decision In Singapore

In Singapore, both public and private hospitals offer advanced facilities for stent or bypass procedures. Here’s what to consider:

• Consult A Cardiologist: A detailed assessment by a heart specialist is essential to determine the best treatment option.
• Cost And Insurance: Check with your insurance provider to understand coverage for stenting or bypass surgery.
• Hospital Choice: Compare the expertise and facilities of different hospitals, especially if opting for private healthcare.

Choosing between a stent or bypass to treat blocked arteries is a significant decision that depends on your specific condition, health status, and preferences. Both procedures have their advantages, and consulting a trusted cardiologist in Singapore is the best way to determine the right treatment for you. By understanding the differences, costs, and recovery processes, you can take a proactive step towards better heart health.
