BACKGROUND: Microcatheter entrapment during embolization of brain arteriovenous malformations (AVMs) represents a potentially harmful technical complication. Although several techniques have been reported for endovascular catheter retrieval from an Onyx cast, such methods have never been demonstrated with acrylic glues. We report a case of removal of a glued microcatheter from an N-butyl cyanoacrylate (NBCA) cast using a microsnare.
METHODS AND RESULTS: A 26-year-old woman presented with an intracranial hemorrhage resulting from a ruptured right choroidal AVM. A microcatheter used for transarterial embolization was unintentionally glued into the NBCA cast. Because attempts to remove the catheter by simple traction failed, a microsnare was used and allowed withdrawal of the entrapped microcatheter without causing damage to the cerebral vasculature. The patient woke up without clinical sequelae.
CONCLUSIONS: Although it is not recommended as routine practice, snaring a glued microcatheter is feasible and can be used in selected cases as a last resort if thromboembolic complications are feared.
