title: Patency of internal mammary artery grafts in no-flow situations.
abstract: We report two cases in which an internal mammary artery graft was found to be nonfunctional in the early postoperative period, but repeat catheterization at 6 months revealed the graft to be patent. These two cases substantiate that closure of an internal mammary artery graft may be reversible.
