Abstract

Coil migration during endovascular treatment of intracranial aneurysms occurs in 2-6% of cases. As endovascular coiling of aneurysms has become increasingly popular and as endovascular technology continues to rapidly evolve, the prevalence of intraprocedural coil migration will invariably rise. Since coil masses are highly thrombogenic, migration out of the aneurysm sac into the parent artery may result in large territory infarcts which subsequently manifest as significant neurological morbidity. Therefore safe and timely retrieval of migrated coils is essential to avoiding poor angiographic and clinical outcomes. A 66-year-old woman with an unruptured 5 × 3 mm, wide-necked posterior communicating artery aneurysm was referred for endovascular treatment. During coiling with the dual catheter technique, both initially deployed coils dislodged from the aneurysm sac and migrated distally into the middle cerebral artery. After failed retrieval with an Alligator device (Chestnut Medical Technologies, Menlo Park, CA, USA), we used two Trevo devices (Concentric Medical, Mountain View, CA, USA) in succession to successfully retrieve the migrated coils. The aneurysm was then occluded with stent-assisted coil embolization. There were no post-procedural angiographic or clinical complications. The patient was subsequently discharged home without neurological deficit. This case illustrates the first use of the Trevo device for retrieval of migrated coils during endovascular treatment of an intracranial aneurysm to our knowledge. Due to the lack of guidelines defining the standard management of intraprocedural coil migration, current strategies are based on retrospective review of published reports and expert opinion. We present a unique and effective method for endovascular retrieval of displaced coils using a Trevo Stentriever device.
