Between May 1995 and October 1997, 17 cases of small patent ductus arteriosus (PDA) underwent percutaneous coil occlusion at the Department of Pediatrics, Chulalongkorn Hospital. The mean age was 5.3 +/- 3.6 years (range, 1 year 4 months to 12.0 years); mean weight was 18.9 +/- 11.7 kg (range, 9 to 48 kg). The mean minimum diameter of the PDA was 2.8 +/- 0.6 mm (range, 1.7 to 4.0 mm). PDA occlusion was achieved with one coil in 9 patients and two coils in 8 patients. One patient required the second coil occlusion procedure to occlude the residual PDA leakage. Of the 17 patients, coils were successfully implanted in 15 patients: complete closure of PDA was obtained in 14 patients, confirmed by aortography or by color flow echo imaging or both. In the two unsuccessful coil implantation cases, coils migrated to the distal left pulmonary artery (1 case) and the distal right pulmonary artery (1 case). They could not be retrieved. Both patients had surgical closure of PDA on the following day after the failed procedure. No clinical and chest X-ray showed any evidence of pulmonary complication from the migrated coils up to 1-year follow-up. PDA coil occlusion provides an alternative to surgical closure. The procedure is safe and has a good result.
1995年5月至1997年10月期间，朱拉隆功医院儿科对17例小型动脉导管未闭（PDA）患者进行了经皮线圈封堵术。平均年龄为5.3±3.6岁（范围为1岁4个月至12.0岁）；平均体重为18.9±11.7千克（范围为9至48千克）。PDA的平均最小直径为2.8±0.6毫米（范围为1.7至4.0毫米）。9例患者使用1个线圈实现了PDA封堵，8例患者使用2个线圈。1例患者需要进行第二次线圈封堵术以封堵残余的PDA渗漏。在这17例患者中，15例成功植入了线圈：14例患者实现了PDA的完全闭合，通过主动脉造影或彩色血流超声成像或两者均证实。在2例线圈植入失败的病例中，线圈分别迁移至左肺动脉远端（1例）和右肺动脉远端（1例）。无法将其取出。这2例患者在手术失败后的第二天均接受了PDA的手术闭合。直至1年随访时，临床和胸部X线检查均未显示迁移的线圈有任何肺部并发症的迹象。PDA线圈封堵术为手术闭合提供了一种替代方法。该手术安全且效果良好。
