Progressive and Late Obstruction of an Aorto-Coronary Venous Bypass Graft
Progressive late obstruction of an aorto-coronary venous bypass graft is reported in a 44-year-old man who died of bi-ventricular failure 114 days after surgery. The first portion of the vein graft had a residual lumen of one mm. Histology showed marked intimal fibrosis. Mechanism for this occlusion and fibrosis is unclear. This representsc the first documented case of late obstruction of an aorto-coronary bypass graft with angiographic evidence of early postoperative patency.
