Between February 1986 and January 1989, 105 percutaneous catheter occlusions of patent ductus arteriosus were undertaken, with six patients having residual left-to-right shunting confirmed by colour-flow Doppler nine months to years after initial occlusion. Five of six had successful reocclusion by placement of a second 12 mm Rashkind device. All successful reocclusions had continuous murmurs. Colour-flow Doppler characterized residual shunting as a discrete jet coursing superior to the device in five and through the pods in one. No left pulmonary artery obstruction was detected following placement of the second device. All patients were discharged the day of or the day following reocclusion.
1986年2月至1989年1月期间，共进行了105例动脉导管未闭的经皮导管封堵术，其中6例患者在初次封堵术后9个月至数年经彩色多普勒证实存在残余左向右分流。6例中的5例通过放置第二个12毫米的拉什金德装置成功再次封堵。所有成功的再次封堵均有连续性杂音。彩色多普勒将残余分流描述为5例中高于装置的离散血流束和1例通过封堵器瓣叶的血流束。放置第二个装置后未检测到左肺动脉梗阻。所有患者均在再次封堵当天或次日出院。
