Coronary Bypass Surgery Without Using Leg Veins
What Is a No-Leg-Vein Bypass?
During coronary bypass surgery, surgeons use blood vessels from other parts of the body to create a new path for blood flow around blocked coronary arteries.
The most commonly used veins are from the legs, but arteries from the chest (internal thoracic artery) and arms (radial artery) can also be used.

Why Chest Arteries Are Preferred
Long-term studies show that bypasses using chest arteries offer the best results.
Leg vein grafts remain open in 50–60% of patients after 10 years.
Chest artery grafts, on the other hand, stay open in 90–95% of patients over the same time period.
Because of these outcomes, chest artery bypasses are generally more beneficial for long-term heart health.

Why Not All Centers Offer No-Leg-Vein Bypass
Bypass surgery without leg veins is more technically challenging and may take longer to perform. For this reason, not all surgical centers routinely offer it.
However, this technique significantly reduces the need for repeat surgeries in the future.
For patients under the age of 65, no-leg-vein bypass surgery is often considered the preferred option, offering better long-term results and fewer complications.
