ABSTRACT
Objective Through compare the clinical data of two kinds of coronary bypass operation under Extacorpeal circulation and Non extracorpoeal circulation in patients over 70 years old with triple-vessel disease, and to provide the clinicalexperience. Methods Choose the patients hospitalized from Department of thoracic sur-gery 115 cases who had had coronary arterybypass grafting surgery from January 2014 to June 2017.there were 51 cases accepted Extracorporeal circulation surgery,Another 64 cases accepted Non-extracorpoeal circulation sur-gery.And make a comparative study of the clinical data of two kinds of coronary bypass operation. Results Com-pared with the Extacorpeal circulation group,the operation time,bypass vessel numb,the Thoracic Drainage were no statistic difference in Non-extracorpoealcirculation(P>0.05),The amount of transfused blood;Mechanical ven-tilation time,Hospitalized time in ICU;Postoperative complications;Total hospitalization time were Significantly lower than Extacorpeal circulation group,the difference was statistically significant(P < 0.05). Conclusions As the development of technology and the maturity of the operator′s experience,Off-pump coronary artery bypass graft-ing is safe and effective in elderly patients,which could be further promoted in clinical practice.
