Ultrasonic prediction of graft failure.
Forty-six femoro-popliteal by-pass grafts have been followed by serial measurements of the pressure indices in the pedal vessels. By this simple ultrasonic technique it has been possible to predict failure in eleven grafts and effect correction in eight. It is suggested that this represents a valuable method of detecting early remediable lesions and improving long term graft patency and limb survival.
