Thirty specially designed 4 French pigtail white Teflon catheters 50 cm in length were utilized for angiography using the retrograde arterial approach in 26 infants and children. Angiographic opacification was considered very satisfactory. Apart from one episode of temporary occlusion of the right coronary artery ostium, there were no other significant complications. The catheters were introduced percutaneously in 21 instances and distal pulses were palpable in 18 patients by the second day after catheterization. At postcatheterization testing with increasing volumes and flow rates, the first rupture occurred, delivering 13 ml at 13 ml/second. On testing an additional 15 catheters using fixed volumes of 5, 10, and 15 ml at increasing flow rates, rupture first occurred at 34, 22, and 18 ml/second, respectively. We conclude that this small catheter is relatively safe and satisfactory for the retrograde arterial approach in the study of infants and children.
30根专门设计的4法式猪尾白色特氟龙导管，长度为50厘米，用于26名婴幼儿和儿童的逆行动脉造影。血管造影显影被认为非常令人满意。除了1次右冠状动脉口暂时闭塞外，没有其他严重并发症。21例经皮插入导管，18例患者在插管后第二天可触及远端脉搏。在导管插入后进行的不同容量和流速的测试中，首次破裂发生在流速为13毫升/秒、输送量为13毫升时。在使用5、10和15毫升固定容量以递增流速测试另外15根导管时，首次破裂分别发生在34、22和18毫升/秒。我们得出结论，在婴幼儿和儿童研究中，这种小导管用于逆行动脉途径相对安全且令人满意。
