[Aorto-coronary venous bypass. The value of microsurgical techniques (author's transl)]

The application of microsurgical techniques to myocardial revascularisation surgery by aorto-coronary venous bypass makes it possible to extend the indications for operation to patients with severe coronary lesions, generally considered to be unsuitable. A technique of vascular suture in two layers combined with a widening angioplasty is described. Their value is illustrated by the blood flow studies and the clinical results in 66 bypass performed on 32 patients.
