Abstract：Objective To summarize the management of extracorporeal circulation ( ECC) during totally thoracoscopic cardiac oper?ation. Methods From January 2013 to June 2014, 123 patients ( 41 males and 82 females) underwent totally thoracoscopic cardiac operation. The venous cannulas were inserted into the internal jugular vein and femoral vein. The vacuum assisted venous drainage ( VAVD) technology was used for enhancing the venous drainage. The arterial cannula was inserted to the right femoral artery for retro?grade perfusion. The flow of ECC was about 60-80 ml/(kg·min) under moderate hypothermia (28-32℃).Antegradecold blood car?dioplegia was delivered via the arotic root.Results The average ECC duration was 117.2±41.8 min and the average aortic cross-clamp time was 73.7±32.1 min. All patients restored heartrhythm spontaneously after release of cross-clamp. The post-operative ventilation time was 13.2±12.7 h and the average thoracic drainage volume was 43.5±74.1 ml at first post-operative day. There was no obvious neurological complication. The average ICU stay was 34.6±32.7 h. Conclusion ECC during the totally thoracoscopic cardiac operation can be established via the peripheral vascular cannulation with the supplement of VAVD support for the venous drainage and provide retrograde perfusion to the whole body. The management of ECC and myocardial protection in these cases are similar with that of con?ventional management.
