Extended use of radial artery with Y-graft technique for complete arterialrevascularization

One of the biggest problems encountered during complete arterial revascular ization is difficulty obtaining sufficient graft length to perform multiple distal anastomoses. We describe a technique of dividing the radial artery during harvest and forming one or more composite Y-grafts to allow end-to-s ide rather than sequential anastomoses without substantially decreasing usa ble conduit length. This approach has merit and may be helpful in some pati ents who require complex arterial grafting. (C) 2001 by The Society of Thor acic Surgeons.
