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.
在治疗颅内动脉瘤过程中，电解可脱弹簧圈（ Guglielmi可脱弹簧圈）可能会出现松解和断裂。使用现有的圈套技术很难取出分离的弹簧圈，并且管腔内的弹簧圈可能会导致载瘤血管血栓形成或远端栓塞。我们报告了1例Guglielmi可脱弹簧圈松解和断裂的病例，该病例通过双导丝技术成功取出。该技术在体外模型中使用10个不同尺寸和直径的弹簧圈进行了评估，在所有试验中均成功取出弹簧圈。
