动脉圆锥支

结论多层螺旋CT是显示和测量右冠状动脉圆锥支的有效工具。

Conclusion There is a higher significance to detect and measure the right conus branch with multi-slice CT .

结果多层螺旋CT可以清楚地显示右冠状动脉圆锥支的起点及走行，结合不同的方法可以对以上数据进行准确的测量。

Results The distribution and shape of the right conus branches could be detected by CT , and with different methods thus data above could be gotten precisely .

深支又依次分出动脉圆锥支、左缘支和前室间隔支。

The deep branch ( anterior descending branch ) gives off arterial cone , left fringe and anterior interventricular septum branches in proper order .

前降支又分出动脉圆锥左支，旋支又分出左缘支。

The anterior descending branch gives off arterial cone left branch again , circumflex branch gives off left fringe branch as wall .

结果动脉圆锥的动脉大都来源于右冠状动脉的圆锥支和左冠状动脉前室间支的动脉圆锥支，它们大都在动脉圆锥部吻合。

Results Arteries of conus arteriosus were mainly branches of conus arteriosus from right coronary artery and branches of conus arteriosus from anterior interventricular artery of left coronary artery . These branches of conus arteriosus were mostly anastomosed in this area .
