title: [Sequential bypass grafting with arterial grafts can be functioned? Assessment of evaluation for function of sequential bypass grafting from theoretical model].
abstract: As total arterial revascularization in coronary artery bypass grafting (CABG) has been recommended, a sequential bypass technique using arterial grafts has been induced. We evaluate whether a sequential bypass graft can be functioned or not by using a simple simulation model for coronary circulation analogous to the electrical circuit based on Ohm law. The ratio of flow between graft and native coronary artery was determined by the severity of stenosis in the bypassed vessels and the graft diameter. In selection for sequential bypass technique, these factors should be taken into consideration.
