Objective:Lung transplantation has become an established option in the therapy of end-stage lung disease.Some of the sequential double-lung transplantations require cardiopulmonary bypass (CPB) support during surgical procedure.However,conventional CPB increases the risks of bleeding and early allograft dysfunction.The purpose of this paper is to introduce the perfusion techniques of extracorporeal membrane oxygenation (ECMO) instead of traditional CPB for sequential double-lung transplantation.
