Services

• Graft Harvest: The surgeon first harvests the LIMA from its natural location in the chest wall. The radial artery is then taken from the patient's arm, usually after a modified Allen's test to ensure adequate blood supply to the hand.
• Y-Graft Construction: The harvested LIMA and radial arteries are then connected in a "Y" configuration. The LIMA typically serves as the main trunk of the "Y," with the radial artery branching off it.
• Coronary Artery Bypass: The Y-grafted arterial conduit is then connected to the blocked coronary arteries downstream of the blockages, effectively creating a new pathway for blood to reach the heart muscle.

Benefits

• Total Arterial Revascularization: Using only arterial grafts is considered superior to using venous grafts because arteries are generally more durable and resistant to atherosclerosis over time.
• Improved Long-Term Patency: Studies show that arterial grafts, particularly the LIMA, have better long-term patency rates (ability to remain open) compared to vein grafts.
• Enhanced Blood Flow: The use of multiple arterial grafts can provide comprehensive and effective revascularization, improving blood flow to the heart.
• Potential for Faster Recovery: Compared to traditional CABG, minimally invasive techniques involving arterial grafts can lead to smaller incisions, reduced pain, and shorter hospital stays.

Considerations

Graft Failure: While arterial grafts are more durable, there is still a risk of graft failure, with studies noting that the radial artery graft can have higher failure rates compared to the LIMA, though comparable to vein grafts.
