心大静脉的应用解剖

Applied anatomy of the great cardiac vein

通过冠状窦逆行灌注１０％明胶墨汁，对１２０例成人心大静脉的起始、行径及其与左冠状动脉分支的毗邻进行了研究。心大静脉６０％起始于前室间沟下１／２．心大静脉和心中静脉在前室间沟下１／３互相连接。通过共同开口的冠状窦组成环绕左室的静脉环达３３．３％．在冠状沟区，心大静脉横过左冠状动脉前室间支和旋支，形成Ｂｒｏｃｑ和 Ｍｏｕｃｈｅｔ血管三角占９６．７％．其中静脉位于动脉浅表的占５９．５％。前室间静脉在前室间沟中１／３出现肌桥４．２％。对心大静脉的临床意义进行了讨论。

One hundred twenty adult heart specimens were used to study the origin ,course and syntopy with the left coronary artery of the great cardiac vein. 60% of the great cardiac veins originate from the lower 1/3 of the anterior interventricular sulcus. It merges with the middle cardiac vein at the lower 1/3 of the sul cus to form a complete venous ring surrounding the left ventricle in 33. 3% of the cases. 96. 7% of the great cardiac veins across the anterior interventricular branch and the circumflex branch of the left coronary artery and form a vascular triangle of Brocq and Mouchet in the coronary sulcus region. 59. 5% of them across the arterial branches superficially. Myocardial bridges of the anterior interventricular vein was observed in the middle 1/3 of the sulcus in 4. 2% of the cases.
