Delayed Herniation of Coil Loop and Spontaneous Reposition in a Superior Cerebellar Artery Aneurysm

Abstract

Herniation of coil loops into the parent artery is one of the complications of endovascular embolization with detachable coils. In this clinical setting, we cannot predict the consequence of the herniated coil loop. We report an unusual case of a superior cerebellar artery (SCA) aneurysm with delayed coil herniation into the basilar artery and spontaneous reposition into the SCA.
