根据组织切片数计算病灶离冠状动脉开口处的距离和病灶的长度；
The length of the lesions and the distance from the beginning of the coronary was calculated depending on the numbers of sections.
左、右冠状动脉在主动脉窦的开口部位，以窦内占多数，分别为87。
Most of the openings of left and right coronary artery were in the aortic sinus, which were 87.
方法：在460例冠状动脉的解剖中，发现7例冠状动脉异常，并对此动脉开口移位和冠状动静脉瘘进行解剖与观察。
Methods: In 460 specimens of hearts, 7 cases of coronary artery malformation were discovered and observed. Careful dissections were made to reveal the structures surrounding abnormal coronary artery.
