Objective To evaluate the preliminary the therapeutic effect of the aortic proximal anastomosis device applied in coronary artery bypass grafting (CABG), and further to assess its safety and feasibility. Methods From January 2006 to May 2007， 50 patients underwent CABG were received the aortic proximal anastomosis device ［Novare Enclose Ⅱ device (Novare Surgical System, Cupertino, CA)］, in which 16 were underwent in onpump CABG and 34 in offpump CABG(OPCAB). The age was 56.2±18.7years(from 55 to 80 years), and there were 38 males and 12 females. Preoperative complications included hypertension in 28 cases, diabetes in 17 cases, old myocardial infarction 18 cases and old cerebral infarction in 15 cases. A total of 175 proximal anastomoses were performed (3.2±1.3), among which there were 152 vein, 12 free left internal mammary artery (LIMA) and 11 radial artery anastomoses. Results Intraoperative transient graft flow meter revealed a satisfactory blood flow. There were no device related complications, and there was no hospital death. 2 cases needed chest re-exploration for hemostasis, 2 cases needed tracheostomy for respiratory insufficiency, and 1 case needed hematodialysis for renal inadequacy caused by diabetic nephropathy. All this 5 patients got recovered and discharged after active treatment. There were no cerebra related complications and no severe cardiac accidents. Follow-up 1 to 3 months after surgery via telephone or letter revealed a 100% survival rate and a 100% exemption rate of cardiac accident. Conclusion Preliminary clinical application of the Novare Enclose Ⅱ device is safe and efficient, but its middle and longterm effect remains to be further observed.
