We report on 14 observations undertaken by ourselves of silent persistent ductus arteriosus (SPDA). During a three year period with the routine use of color doppler flow evaluation we found cases of SPDA in 14 children. A very little ductus arteriosus is already known to us through earlier heart catheter examinations which were undertaken because of other isolated heart defects (16 cases in 345 isolated heart defects over 10 years). We also consider the fact that SPDA is not an infrequent result after the occlusion of a patent ductus arteriosus with the Rashkind-Occluder-System and after operative ligatures of patent ductus arteriosus. Finally, we compare our results concerning the frequency of SPDA with current literature and discuss consequential therapies.
我们报告了我们自己对14例无症状持续性动脉导管未闭（SPDA）的观察结果。在三年期间，通过常规使用彩色多普勒血流评估，我们在14名儿童中发现了SPDA病例。通过早期因其他孤立性心脏缺陷而进行的心脏导管检查，我们已经了解到存在非常小的动脉导管未闭（在10年期间，345例孤立性心脏缺陷中有16例）。我们还考虑到这样一个事实，即使用拉什金德封堵器系统封堵动脉导管未闭以及对动脉导管未闭进行手术结扎后，SPDA并非罕见的结果。最后，我们将我们关于SPDA发生率的结果与当前文献进行比较，并讨论相应的治疗方法。
