Investigations on the morphophysiological basis of revascularization of the myocardium by the Vineberg method

A study was carried out on the dynamics of vasculogenesis and the formation of mammary-coronary anastomoses within the first seven months after implantation of the internal mammary artery in the left ventricular myocardium, according to the Vineberg method. The efficiency of these anastomoses was demonstrated 4 to 7 months later by the absence of lesions 8 to 10 days after transitory and permanent myocardial ischaemia induced by coronary obliteration. The lesions could not be prevented in the case of thrombosis of the internal mammary artery or when ischaemia was produced concomitantly with the implant or before the mammary-coronary arteriolo-arterial anastomotic network developed.
