We report the successful re-screwing of the embolized duct occluder (DO) in three children for retrieval and to attempt redeployment. The DO was embolized into descending aorta immediately after the deployment in one child and within 24 h after the procedure in two further patients. The DO was re-screwed back by the DO delivery cable, using "sheath in sheath" in all three cases; however, successful retrieval could be done only in two. Repositioning in the patent ductus arteriosus (PDA) was done using the same device in those two children and surgical removal was needed in third child with perimembranous ventricular septal defect.
我们报告了3例儿童患者成功地重新旋拧已栓塞的导管封堵器(DO)以进行取出并尝试重新部署的情况。在1例儿童患者中,封堵器在部署后立即栓塞入降主动脉,另外2例患者在术后24小时内发生栓塞。在所有3例病例中,均使用“鞘中鞘”技术通过DO输送缆线将DO重新旋拧回去;然而,仅2例成功取出。在这2例儿童患者中,使用同一装置在动脉导管未闭(PDA)中重新定位,第3例患有膜周部室间隔缺损的儿童患者则需要手术取出。
