[Technical problems in coronary bypass surgery (author's transl)]

The problem of selecting the most suitable operative technique for coronary bypass surgery is demonstrated by a comparison of the most current methods. The fact, that comparable results can be obtained by various technical modifications makes it appear reasonable to choose an method as simple as possible for routine. Therefore, the following procedure is recommended: Extra-corporeal circulation with hemodilution and systemic as well as local hypothermia. Distal anastomoses under ischemic cardiac arrest without vent. Proximal anastomoses under partial extra-corporeal circulation with the heart beating. Continuous suture technique for all anastomoses. Our own clinical results with 1,3% early mortality, 1% perioperative myocardial infarctions and 94% graft patency after 1 month prove the feasibility of this operative procedure.
