Coronary Bypass Surgery in Thailand

Coronary artery bypass grafting may be considered when coronary arteries supplying the heart have become significantly narrowed or blocked.

Commonly known as CABG or heart bypass surgery, the operation creates new pathways for blood to flow around blocked sections of the coronary arteries.

Thailand offers specialist cardiothoracic surgeons, advanced cardiac imaging and comprehensive heart-surgery facilities for international patients considering planned bypass surgery.

Siam Medica can help you explore suitable providers, share cardiac records for specialist review, request personalised treatment plans and cost estimates, and coordinate your care before, during and after treatment in Thailand.

What is coronary bypass surgery?

CABG is a surgical treatment for coronary artery disease.

During the operation, the surgeon uses healthy blood vessels from another part of the body to create new routes around blocked coronary arteries.

These grafts allow blood to reach the heart muscle without passing through the narrowed sections.

Depending on the extent of coronary disease, one or several bypass grafts may be required.

When may CABG be considered?

Bypass surgery may be recommended when coronary artery disease is extensive or located in areas where surgery may provide a more appropriate treatment than angioplasty.

Factors considered can include:

• Number of blocked arteries

• Location of the blockages

• Complexity of coronary disease

• Severity of symptoms

• Heart function

• Diabetes or other medical conditions

• Previous angioplasty or stent treatment

• Overall health

The decision between CABG, angioplasty and medical treatment should be made after specialist cardiac assessment.

CABG versus coronary angioplasty

Both CABG and coronary angioplasty aim to improve blood flow to the heart.

Angioplasty and stenting open narrowed arteries from inside using catheter-based techniques.

CABG creates alternative blood-flow pathways around the narrowed arteries.

Angioplasty generally involves a shorter recovery.

CABG is a larger operation but may be considered more appropriate for some patients with extensive or complex coronary artery disease.

The most suitable approach depends on individual coronary anatomy and medical circumstances.

Types of bypass graft

Several blood vessels can be used to create bypasses.

These may include:

• Internal mammary arteries from the chest

• Radial arteries from the arm

• Veins from the leg

The surgical team selects grafts according to the location of the blockages and the patient's individual anatomy.

More than one type of graft may be used during the same operation.

On-pump CABG

Traditional bypass surgery may be performed using a heart-lung bypass machine.

The machine temporarily performs the work of the heart and lungs while the surgeon creates the bypass grafts.

This is commonly known as on-pump CABG.

Off-pump CABG

In selected patients, surgeons may perform bypass surgery while the heart continues beating.

This is known as off-pump CABG.

Specialised equipment stabilises the area of the heart being treated.

Not every patient is suitable for this approach, and the decision depends on coronary anatomy, surgeon preference and individual medical factors.

Minimally invasive CABG

Some patients may be suitable for minimally invasive coronary bypass surgery.

This uses smaller incisions rather than a conventional full breastbone opening.

The technique may be used for selected patterns of coronary disease.

Potential advantages can include less tissue disruption and a different recovery profile.

However, minimally invasive CABG is not suitable for every patient and may involve higher technical complexity.

Assessment before bypass surgery

Patients considering CABG generally undergo detailed cardiac assessment.

This may include:

• Coronary angiography

• Echocardiogram

• Electrocardiogram

• Blood tests

• Chest imaging

• Assessment of heart function

• Kidney and lung function testing

• Evaluation of the arteries supplying the brain where appropriate

The cardiology and cardiac-surgery teams use these results to determine whether bypass surgery is appropriate and how many grafts may be required.

International patients can often submit cardiac records and imaging before travel for preliminary review.

Preparing for surgery

Before surgery, patients usually undergo medical clearance and anaesthetic assessment.

The team reviews:

• Current medication

• Blood-thinning medication

• Diabetes treatment

• Blood pressure

• Kidney function

• Lung health

• Smoking history

• Other medical conditions

Medication should not be stopped or changed unless the treating team gives specific instructions.

The CABG procedure

CABG is performed under general anaesthesia.

In conventional surgery, the surgeon accesses the heart through the chest.

Healthy blood vessels are harvested and connected above and below the blocked sections of coronary arteries.

This allows blood to bypass the narrowed areas.

The number of grafts depends on the number and location of significant blockages.

After surgery, patients are transferred to intensive or critical care for close monitoring.

Hospital stay and early recovery

Patients generally spend the first stage of recovery in intensive or intermediate cardiac care.

Monitoring includes:

• Heart rhythm

• Blood pressure

• Breathing

• Surgical wounds

• Fluid balance

• Kidney function

• Pain control

Walking and breathing exercises usually begin during the hospital stay as the patient's condition stabilises.

A planned CABG admission commonly involves around one week in hospital.

Recovery after CABG

Recovery continues for several weeks after discharge.

Patients gradually increase:

• Walking

• Everyday movement

• Household activity

• Cardiovascular exercise

If the breastbone has been opened, it requires time to heal.

Heavy lifting and strenuous upper-body activity are therefore normally restricted during the early recovery period.

Cardiac rehabilitation may help patients rebuild fitness safely and address cardiovascular risk factors.

Life after bypass surgery

CABG improves blood flow but does not eliminate the underlying process of coronary artery disease.

Long-term treatment therefore remains important.

This can include:

• Cholesterol-lowering medication

• Blood-pressure treatment

• Antiplatelet medication

• Diabetes management

• Smoking cessation

• Regular physical activity

• Heart-healthy nutrition

• Ongoing cardiology follow-up

Lifestyle and medication management help protect both the native coronary arteries and bypass grafts.

Risks and considerations

CABG is major heart surgery.

Potential risks include:

• Bleeding

• Infection

• Abnormal heart rhythms

• Heart attack

• Stroke

• Kidney injury

• Breathing complications

• Blood clots

• Wound-healing problems

• Temporary confusion or cognitive changes

• Complications related to anaesthesia

• Need for additional cardiac treatment

Risk varies according to age, general health, severity of heart disease and whether the operation is planned or performed in an emergency.

Planned international treatment should only be considered for patients who are medically stable enough to travel.

Coronary bypass surgery costs in Thailand

The cost of CABG in Thailand varies according to the complexity of coronary disease and surgical approach.

A broad indicative range is approximately US$35,000–52,000 or more.

Factors affecting the total cost can include:

• Number of bypass grafts

• Conventional or minimally invasive surgery

• On-pump or off-pump procedure

• Pre-operative cardiac investigations

• Surgeon and anaesthesia fees

• Intensive-care requirements

• Length of hospital stay

• Medication

• Treatment of other medical conditions

• Additional cardiac procedures

Siam Medica can request a personalised treatment plan and cost estimate after suitable providers have reviewed your coronary angiography and medical records.
