Abstract
|
|
|
|
Coil prolapse or migration is a rare but potentially serious complication that may occur during aneurysm embolization, with no standard management currently described. Here we describe our experience with the Embolus Retriever with Interlinked Cages (ERIC) device® (Microvention, Aliso Viejo, CA, USA) for the retrieval of prolapsed or migrated coils in a case series and Flow-Model analysis. First, a retrospective review was performed using our institution database for patients in which coil prolapse or migration occurred during aneurysm embolization, and data was collected and analyzed. Second, an in vitro Flow-Model analysis was performed comparing the ERIC device® with other stent retrievers for coil retrieval. In 2 cases, the ERIC device® successfully retrieved the displaced coil from intracranial circulation in 1 pass, after failure with other devices. In the Flow-Model, again the ERIC device® achieved success for retrieving a detached coil, whereas 2 other different stent retrievers failed to capture the coil after 2 attempts. The ERIC device® appears to be a safe and effective tool for retrieving a prolapsed or migrated coil from the intracranial circulation.
