Objective To evaluate surgical methods and results of extracardiac conduit total cavopulmonary anastomosis （EC-TCPA） without cardiopulmonary bypass （CPB）. Methods From May 2000 to April 2003

11 patients with functional univentricle underwent off-pump EC-TCPA （no-CPB group）. Their postoperative outcome was retrospectively compared with a 17-patient group who underwent EC-TCPA with cardiopulmonary bypass （CPB group） over a concurrent time period. Results There was 1 operative death in no-CPB group and 2 in CPB group; early postoperative hemodynamics appe-ared to significantly improve in no-CPB group. Blood and platelet transfusions decreased and blood plasma transfusion significantly lowered in no-CPB group compared with CPB group （P = 0.036）. Postoperative courses of patients in no-CPB group were smooth and event free

and extubation time was substantially short. Intensive cares unit stay （P = 0.04） and hospital stay （P = 0.02） postoperation were significantly shorter

hospital costs were significantly reduced （P = 0.004） in no-CPB group compared with CPB group. Conclusions EC-TCPA without use of CPB is not a difficult procedure; the procedure results in improvement in postoperative hemodynamics

and decreased use of blood and blood products. It is a more efficient operation with more short recovery time and reduced hospital stay.
