Saphenous Vein as Y-composite Versus Aortocoronary Conduit for CABG
Recruiting now · Not applicable
Conditions studied: Coronary Artery Disease
In brief
Left internal thoracic artery (LITA) has been acknowledged as the first graft of choice for coronary artery bypass grafting (CABG). However, it is still not conclusive which one is the best second graft of choice among right internal thoracic artery, radial artery, right gastroepiploic artery, saphenous vein, and etc., as well as its configuration for CABG. In our institution, saphenous vein has been primarily used for the second graft and we have harvested it with 'No touch technique'. We have been demonstrated the excellent long-term patency of this 'No touch saphenous vein' in many studies. However, it is still unknown which configuration is the better strategy for the saphenous vein as a Y-composite graft based on the left internal thoracic artery versus an aortocoronary conduit. Thus, we aimed to evaluate morphologic change of saphenous vein graft by 1-year intravascular ultrasound (IVUS) study and angiographic patency results between Y-composite graft and aortocoronary conduit.

You may qualify if…
- A patient who is going to receive coronary artery bypass grafting
- Older than 19 years
- Coronary artery bypass grafting is going to be performed with left internal thoracic artery and saphenous vein graft
You may not qualify if…
- Other concomitant procedures (e.g. valve or aorta surgery) is planned
