RETRIEVAL OF A GUGLIELMI DETACHABLE COIL AFTER UNRAVELING AND FRACTURE - CASE-REPORT AND EXPERIMENTAL RESULTS

UNRAVELING AND FRACTURE of electrolytically detachable coils (Guglielm i detachable coils) may occur during treatment of intracerebral aneury sms. Retrieval of the detached coil is difficult using existing snare technology, and the intraluminal coil may cause parent vessel thrombos is 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 succ essful coil retrieval in all trials.
