title: Flow in sequential vein grafts with diamond anastomoses.
abstract: Flow in single grafts was compared to flow in sequential grafts with diamond anastomoses to the branches of the right and circumflex coronary arteries. The mean flow was 36 ml/min for single grafts, 51 ml/min for sequential grafts with one diamond anastomosis, and 69 ml/min for sequential grafts with two diamond anastomoses. The flow in two single grafts, 72 ml/min, was significantly more than the flow in sequential grafts with one diamond anastomosis and equalled the flow in sequential grafts with three distal anastomoses. Constructing diamond anastomoses with interrupted sutures did not significantly enhance flows in sequential grafts.
