Embolizations of coils and devices are well-known complications of transcatheter procedures performed in order to occlude extracardiac or intracardiac shunts. A review of the literature and of our experience was performed to provide a succinct review of existing transcatheter retrieval techniques. After embolization of a coil or device, the appropriate initial procedure involves repositioning of the coil or device using a snare or bioptome to a location where harm to the patient is minimized. The subsequent retrieval technique depends on the characteristics of the coil or device involved. Coils may be retrieved using a bioptome or a snare. Devices must be snared, often in specific places. Both may be pulled into long or short, appropriately sized retrieval sheaths. To minimize potential morbidities associated with these retrievals and to maximize efficacy of retrieval, operators performing transcatheter coil or device occlusions must be familiar with retrieval techniques.
线圈和装置的栓塞是为封堵心外或心内分流而进行的经导管操作的常见并发症。为了简要回顾现有的经导管取出技术，我们对文献和自身经验进行了回顾。在一个线圈或装置发生栓塞后，合适的初始操作包括使用圈套器或活检钳将线圈或装置重新定位到对患者造成伤害最小的位置。后续的取出技术取决于所涉及的线圈或装置的特性。线圈可以使用活检钳或圈套器取出。装置必须用圈套器取出，通常在特定位置。两者都可以被拉入长度合适的长或短的取出鞘中。为了尽量减少与这些取出操作相关的潜在发病率并最大化取出效果，进行经导管线圈或装置封堵的操作人员必须熟悉取出技术。
