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?
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.
No takes yet. Share an insight, caveat, or question.
Modified techniques were associated with higher patency; hypothesis-generating and requires randomized confirmation before practice change.
Campeau et al. (1975) studied this question.
