[Pressure measurement of coronary artery bypass graft with transducer-tipped catheter].
The pressure of in situ arterial graft was measured with Fiber Optic Transducer-Tipped Pressure Monitoring System (Camino). Internal thoracic artery (ITA) and gastroepiploic artery (GEA) were prepared as in situ grafts, and the pressure at the end of each graft was recorded with ascending aortic pressure (Ao) and electrocardiogram, simultaneously. Although the peak systolic pressures of these grafts were identical, the systolic pressure of ITA and GEA formed narrow contours. While the diastolic pressures of Ao was sustained and high, the diastolic pressures of ITA and GEA showed rapid falling. Therefore, ITA and GEA had the risk of inadequate blood supply. This pressure measurement of in situ arterial graft was an easy and effective method for presumption of the ability of blood supply.
