关于起自肺动脉的副冠状动脉的形态观察,文献上,仅查到有个例报告。本文在300个人心脏标本上,观察到12例起自肺动脉的副冠状动脉;出现率为4.0％。报告如下: 材料方法:300个心脏均经福尔马林固定过的。其中,成年人心脏124个,未成年人心脏176个。观察肺动脉窦及其附近的动脉壁上有无开口;且剥制肺动脉根部外面,找出与开口相连的血管。于细微处,借助放大镜进行观察。结果:(见附表) (一)、起自肺动脉的副冠状动脉,在124个成人心脏中,有3例,占2.4％;在176个未成年人心脏中,有9例,占5.1％。 (二)、开口:12例起自肺动脉的副冠状动脉全部开口于前肺动脉窦及其上缘附近。其中,开口位于窦的中三分之一份的,有9例;位于左三分之一份的,有2例;位于右三分之一份的,有1例。在纵向位置上,开口于窦内的,有7例;于窦边的,有3例;于窦外
Regarding the morphological observation of the para-coronary artery from the pulmonary artery, only one case was reported in the literature. In this paper, in 300 human heart specimens, 12 cases of the secondary coronary artery from the pulmonary artery were observed; the incidence rate was 4.0%. The report is as follows: Material Methods: All 300 hearts were fixed with formalin. Among them, there are 124 adult hearts and 176 juvenile hearts. Observe the pulmonary sinus and its adjacent artery wall with or without opening; and stripped outside the root of pulmonary artery to find the blood vessels connected with the opening. In the subtle, with a magnifying glass for observation. Results: (see attached table) (a), from the pulmonary artery of the paratracheal artery, in 124 adult heart, 3 cases, accounting for 2.4%; 176 of the juvenile heart, 9 cases, 5.1% . (B), the opening: 12 cases of para-coronary artery from the pulmonary artery all openings in the anterior pulmonary sinus and its vicinity. Of these, 9 were located in the third third of the sinus, 2 in the left third, and 1 in the right third. In the longitudinal position, the opening in the sinus, there are 7 cases; in the sinus, there are 3 cases; outside the sinus
