[Abstract] Objective To explore the value of extracorporeal circulation technique in minimally invasive cardiac surgery，and to summarize the experience of extracorporeal circulation management of minimally invasive cardiac surgery. Methods 121 cases undergoing minimally invasive cardiac surgery assisted by extracorporeal circulation in Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology from January 2012 to March 2016 were selected，among whom，there were 91 cases of total laparoscopic surgery，28 cases of thoracic small incision assisted surgery，2 cases of Da Vinci robot assisted surgery；there were 3 cases of aortic valve replacement，68 cases of mitral valve replacement，5 cases of mitral valvuloplasty，33 cases of repair of atrial septal defect，12 cases of ventricular septal defect repair；aged 17-64 years old，with 69 cases of male and 52 cases of female. In the femoral artery and femoral

vein，the catheter was set up in cardiopulmonary bypass to complete the operation. Results The cardiopulmonary bypass time was （91.37±47.24）min，aortic blocking time was （57.63±34.66）min. All cases of extracorporeal circulation stopped smoothly and completed the operation safely. Conclusion In view of the characteristics of minimally invasive cardiac surgery，the improvement of technical details and reasonable selection of auxiliary equipment，peripheral cardiopulmonary bypass technology can assist the current major minimally invasive cardiac surgery safely and smoothly.

泛应用的一大技术瓶颈。而随着技术进步、各类插管及其技术的改良、辅助引流等技术的推广，周围体外循环技术正为
