Abstract:
During surgery for lung cancer in a patient who had undergone coronary artery bypass grafting through the descending aorta by left thoracotomy, we measured graft bypass blood flow from the descending aorta under intraaortic balloon pump (IABP) assistance. Under IABP assistance, the diastolic waveform changed to a spiky pattern with a sharp drop in blood flow of approximately 16% compared to that without IABP assistance. We report changes in graft flow pattern during IABP assistance when the graft is placed from the descending aorta.
