title: Embolization and transcatheter retrieval of coils and devices.
abstract: 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.
