Angiographic Assessment of Sequential and Individual Coronary Artery Bypass Grafting

Abstract

The patency of a sequential vein conduit is generally superior than that of an individual one, especially for poor runoff coronary vessels, provided that the most distally located anastomosis is performed on a good coronary artery in terms of quality and diameter. Using a minimal length of SVG is another advantage. However, failure of a single sequential conduit jeopardizes all of the anastomoses along that graft segment. Besides, being technically more demanding, technical expertise in performing a sequential anastomosis is probably among the important predictors of patency.
