Key result
Aortocoronary vein grafts placed in 7 patients led to a substantial increase in proximal occlusive disease in 6 of 9 bypassed arteries, including complete obstruction in 4 vessels.
Why the study?

Does aortocoronary vein grafting accelerate proximal occlusive disease in patients with severe proximal stenosis?
Successful aortocoronary vein grafts may accelerate occlusion of the native proximal coronary artery, potentially due to competitive flow diversion.
Bousvaros et al. (1972) conducted an observational in Severe proximal coronary stenosis (n=7). Aortocoronary vein grafts was evaluated on Increase of proximal occlusive disease. Aortocoronary vein grafts placed in 7 patients led to a substantial increase in proximal occlusive disease in 6 of 9 bypassed arteries, including complete obstruction in 4 vessels.
