Abstract

The ductus arteriosus was studied in 138 dogs (80 female and 58 male) aged from 6 h to 21 days. This experiment led us to conclude that the anatomical closure of the d. arteriosus starts within 96 h and is obliterated after 6 days in 100% of the animals studied. We have also evidenced that the closure starts in the medial part of the d. arteriosus and progresses to the pulmonary artery and aorta.

摘要

对138只年龄从6小时至21天的犬(80只雌性和58只雄性)的动脉导管进行了研究。该实验使我们得出结论,动脉导管的解剖学闭合在96小时内开始,并且在研究的100%的动物中,6天后完全闭塞。我们还证明,闭合始于动脉导管的内侧部分,并向肺动脉和主动脉发展。
