Abstract
I have studied on myocardial revascularization after several vascular implantation procedure on the ischemic heart of dogs. And the studies were examined in morphological. Myocardial ischemic produced by gradual constrictors using the laminaria. The results were as follows.
1. Gradual occlusion of the coronary artery can be interpreted as the result of the evolution of intercoronary collateral anastomosis in each groups.
2. Complete obstruction of the anterior descending artery promotes obviously the formation of implanted internal mammary-coronary artery anastomosis and the size of the anastimosis vessel would be 600μ.
3. Formation of the internal mammary-coronary artery anastomosis was observed at least 38 days after implant. But the developed fibrous medial hypertrophy was observed in the internal mammary artery.
4. On the group using the non-side hold implanted internal mammary artery, the patency of the implanted vessels wasn't observed an averaged of 30 days.
5. On the method of the implantation of the vessel using the free vein graft, coa-gulated blood is apt to be produced in the vein graft.
