Figure 3. (A-1) Reopening of saphenous vein (SV) composite graft based on the in situ left internal thoracic artery (ITA) in a 64-year-old man. The left ITA was anastomosed to the left anterior descending coronary artery (black arrows), and the SV conduit was anastomosed to the diagonal (black arrowheads), obtuse marginal (white arrowheads), and posterior descending (PDA [white arrows]) arteries. The SV conduit distal to its anastomosis with the obtuse marginal artery was not opacified as shown by graft angiography on early postoperative angiogram. (A-2) The SV conduit anastomosed to the PDA also was not visualized retrogradely as shown by native right coronary angiography. (B) The SV conduit anastomosed to the PDA was reopened as shown by graft angiography on 1-year angiogram.
