目的 探讨羊心脏左冠状动脉的解剖结构 ,丰富动物实验资料。方法 局解手术学实验后处死山羊 ,取羊心 90例 ,经 10 %甲醛固定 ,手工剥制显示左冠状动脉 ,6例用过氯乙烯 乙酸乙脂填充剂注入冠状动脉中制成动脉血管铸型 ,测量左冠状动脉及其分支。结果 羊冠状动脉分左、右冠状动脉 ,左冠状动脉粗大较浅表 ,前降支行于心肌表面或深达心肌不能明视 ,上多附有心肌桥 ,旋支粗大行程长分支多 ,二者之间多有对角支出现。羊心冠状动脉为左优势性。结论 羊冠状动脉与人相比有较大差异
Objective To investigate the anatomy of the left coronary artery in sheep and to enrich the experimental data of the animal. Methods After surgical operation, goats were sacrificed and 90 cases of goat heart were fixed with 10% formalin. The left coronary artery was manually dissected, and the other 6 cases were injected with coronary artery into the coronary artery. Type, measuring the left coronary artery and its branches. Results Sheep Coronary artery points left and right coronary arteries, the left coronary artery thicker superficial, anterior descending branch in the myocardial surface or deep myocardial infarction can not be seen, the more attached to the myocardial bridge, There are many diagonal payments between. Sheep heart coronary artery is left dominant. Conclusion Sheep coronary artery compared with people are quite different
