Endovascular coiling has become the preferred treatment of many centers for the management of both ruptured and unruptured aneurysms. Coil migration is a rare complication that can lead to vessel occlusion in 90% of the cases. Endovascular techniques for coil retrieval have shown less complication rates than open surgery. Stent retriever devices have been successfully used for the retrieval of proximally migrated coils, however, distally migrated coils still represent a challenge with greater risk of complications. In the present technical video 1, we demonstrate the successful retrieval of a distally M3 migrated coil using a 3 mm Trevo XP ProVue stent riever (Stryker Neurovascular, Fremont, CA, USA) in combination with proximal aspiration.
