Packed red blood cell (RBC) transfusions are associated with increased mortality after coronary artery bypass grafting (CABG) but not after cardiac valve operations. Transfusions are associated with increased strokes and deep venous thromboses after cardiac operations as well as increased peripheral vascular graft thrombosis. The purpose of this study was to determine if RBC transfusions were associated with a greater hazard of an occluded graft developing after CABG.


Patients who underwent symptom-driven coronary artery angiography after CABG were analyzed using Cox models and propensity scoring to compare outcomes based on the RBC transfusion status during their index CABG hospitalization.


We analyzed 940 patients. We found that patients who received transfusions were more likely to have occluded grafts on angiography (hazard ratio [HR], 1.24; 95% confidence interval [CI], 1.03-1.50; p = 0.02). After adjusting for other factors, we found that RBC transfusion was associated with about a 20% increased hazard of graft occlusion (HR, 1.21; 95% CI,1.07-1.37; p = 0.003).


Perioperative RBC transfusion is associated with graft occlusion after CABG at both the patient and graft levels. These results add to the growing body of evidence that homologous RBC transfusion is not risk free but is associated with a variety of adverse effects including midterm graft failure.

ESCVS poster accepted

We are very pleased to accounce the acceptance of a study comparing donor blood transfusion rates and volumes with AvanCell(TM) Bio-Regenerative Fibrin System against current standard of care for a poster presentation at the 64th ESCVS, International Congress of the European Society of Cardiovascular and Endovascular Surgery in Istanbul, 26-29 March 2015.

Donor blood transfusions 30% higher mortality - SRF 1 Puls with Prof. D. Spahn

A documentary program on Swiss television, SRF 1 Puls, aired 26 January 2015 discussed the risk factors associated with donor blood transfusions. Prof. Donat Spahn outlined his 'patient blood management' concept whereby all steps are taken to reduce donor blood tranfusions peri-operatively. The program stated a 30% higher mortality recorded with those receiving DBTs vs. those that do not.
