副冠状动脉的解剖学观察及其临床意义

Morphological study of accessory coronary artery and its clinical significance

目的 研究副冠状动脉的形态 ,为临床心脏治疗提供解剖学依据并积累人类体质学方面的资料。方法 解剖经福尔马林固定的 6 7例正常人心脏的血管 ,对副冠状动脉进行形态学观测。结果 ① 6 7例心脏中有18例存在副冠状动脉 ,出现率为 2 6 .9% ;其中 ,16例有 1支副冠状动脉 ,2例有 2支副冠状动脉。在这 2 0支副冠状动脉中 ,19支起于主动脉右窦 ,1支起于主动脉后窦。副冠状动脉主要分布于动脉圆锥。②副冠状动脉和相应右冠状动脉起始处的直径平均分别为 (1.92± 0 .6 6 )mm和 (4.6 0± 1.4 3)mm ,两者的距离平均为 (2 .32± 0 .84 )mm。结论 副冠状动脉在临床实践中具有实用意义。

Objective To investigate the morphology o f accessory coronary artery and to privide the anatomical data for treatment of he art and to accumulate materal for physical anthropology.Methods Accessory coronary artery was observed and measured on 67 hearts of norma l cadavers fixed with formaldehyde.Results ①Accessory co ronary arterys appeared in 18 of 67 specimens, and the prevalence of them was 26 .9%. Of the 18 specimens, Accessory coronary arterys exhibited 1 (16 cases) and 2 ( 2 cases). Of the 20 accessory coronary arterys, 19 arised from the right aor tic sinus and 1 arised from the posterior aortic sinus. Accessory coronary arter ys mostly supplied the conus arteriosus. ②The diameters of the roots of the acc essory coronary artery and right coronary artery were (1.92±0.66)mm and (4.60± 1.43)mm respectively, and the distance between them was (2.32±0.84)mm. Conclusion The accessory coronary artery showed significance in cl inical practice.
