Figure 2 Indocyanine green angiogram of a saphenous vein graft. (A) There is contrast dye in the vein graft (white arrow), but no dye enters the distal posterior descending coronary artery (black arrow). The distal anastomosis was reopened, and an occlusive stitch was found penetrating through the posterior wall of the target coronary vessel preventing antegrade flow. The anastomosis was revised. In the post-revision angiogram (B), contrast was observed to rapidly fill the vein graft (white arrow) and distal coronary vessel (black arrow).
