In some newborns with vital distress, conventional umbilical artery catheterization cannot be performed: in our series, this occurred in 34 out of 248 attempts. In 28 of these 34 infants, catheterization succeeded when hypogastric cut-down of an artery was carried out. Two of the 6 failures were due to a minor complication at the time of the cut-down, while two others occurred in infants presenting a single umbilical artery. The usual cuse of failure of conventional catheterization is probably laceration of the artery wall and ensuing subintimal fistulas and perforation.
在一些有生命危险的新生儿中，无法进行传统的脐动脉插管：在我们的系列研究中，248次尝试中有34次出现这种情况。在这34例婴儿中的28例中，当进行下腹动脉切开术时插管成功。这6例失败中有2例是由于切开术时出现轻微并发症，另外2例发生在只有单条脐动脉的婴儿中。传统插管失败的常见原因可能是动脉壁撕裂以及随之而来的内膜下瘘管和穿孔。
