Saphenous Vein as Y-composite Versus Aortocoronary Conduit for CABG
Comparison Between the Saphenous Vein as Y-composite Graft Based on the Left Internal Thoracic Artery Versus Aortocoronary Conduit for Coronary Artery Bypass Grafting: A Prospective Randomized Controlled Trial
Source: ClinicalTrials.gov · Last updated 17 Sept 2026
Brief summary (registry, in English)
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.

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Other concomitant procedures (e.g. valve or aorta surgery) is planned
Other illness
- Patients with severe comorbidities which limit the life expectancy of them below 1 year (e.g. terminal cancer)
- Patients who have connective tissue disease
Other
- Patients whose left internal thoracic artery or saphenous vein is not available due to the low quality, severe injury, or absence of the graft
- Patients whose ascending aorta is not suitable to aortocoronary anastomosis (e.g. ascending aorta aneurysm, porcelain aorta)
- Emergency operation
- Reoperative coronary artery bypass grafting
Who the study is looking for
- A patient who is going to receive coronary artery bypass grafting
