Retrieval of a Guglielmi detachable coil after unraveling and fracture: case report and experimental results.

Author information

Department of Neurosurgery, State University of New York at Buffalo.


Unraveling and fracture of electrolytically detachable coils (Guglielmi detachable coils) may occur during treatment of intracerebral aneurysms. Retrieval of the detached coil is difficult using existing snare technology, and the intraluminal coil may cause parent vessel thrombosis or distal embolization. We report a case of unraveling and fracture of a Guglielmi detachable coil that was successfully retrieved using a dual guidewire technique. The technique was evaluated in an in vitro model using 10 coils of varying sizes and diameters, and allowed successful coil retrieval in all trials.
