Why the study?
Do modified surgical techniques improve angiographic patency of aortocoronary saphenous vein grafts at two weeks and one year compared to original techniques?

Modified techniques were associated with higher patency; hypothesis-generating and requires randomized confirmation before practice change.
Do modified surgical techniques improve angiographic patency of aortocoronary saphenous vein grafts at two weeks and one year compared to original techniques?
Modifications in surgical techniques for aortocoronary saphenous vein grafts significantly improved one-year angiographic patency rates and reduced the incidence of late graft stenoses.
Campeau et al. (1975) studied this question.
