[Permeability of venous aortocoronary bypass 5 years later].
47 consecutive patients who had undergone aorto-coronary venous bypass surgery (mean: 1.6 graft per patient) have been investigated after a mean follow-up period of 5 years and 9 months (range: 44-108 months). 52 grafts out of 73 were found to be patent (71 p. 100), the best patency rate being shown by grafts on the LAD artery (27/32 = 85 p. 100). Long-term graft patency may be associated with an improved left ventricular ejection fraction; 77 p. 100 of the total patients experienced a lasting clinical benefit from the operation.
