Description
Summary:Objective: We report a case in which two coils became stuck in a microcatheter at the end of coil embolization for a cerebral aneurysm.Case Presentation: Two coils became stuck in the microcatheter at the final stage of stent-assisted coil embolization for an unruptured anterior communicating artery aneurysm. The rear end of a detached coil was near the tip of the microcatheter. The coil inserted next was pushed out of the microcatheter and pulled back into the microcatheter. Then, the rear end of the detached coil and the retracted coil meshed into the microcatheter, and became immobile. The microcatheter and these two coils were removed simultaneously, and coil embolization was finished.Conclusion: At the end of coil embolization, the filling rate is relatively high. Insertion of another coil and traction may cause the coils to become stuck in the microcatheter.
