title: Surgical recanalization of distal middle cerebral artery occlusion due to a coil migration during endovascular coil embolization: a case report.
abstract: Coil migration into the parent artery during endovascular coil embolization is a rare, but life-threatening complication, which can induce thromboembolism and result in poor outcome. A 63-year-old man was referred to Chonbuk National University Hospital emergency center due to migration of a coil for a left middle cerebral artery bifurcation unruptured aneurysm. We performed an emergency craniectomy to remove the coil migrated to the distal M2 branch and thrombus, and aneurysmal neck clipping for his aneurysm. Fortunately, at the six month follow-up, the patient did not show any noticeable neurological sequela. In case of parent artery occlusion due to coil migration an immediate recanalization should be performed by a neurovascular specialist who can provide both surgical treatment and endovascular management in order to prevent severe sequela or even death.
