Delayed Coil Migration: Uncommon Cause of Ischemic Stroke and Retrieval Technique

Abstract

A 51-Year-old woman had balloon assisted coil embolization with two microcoils for a residual of a previously
ruptured right posterior communicating artery aneurysm
[Figure 1(A) and (B)]. The patient presented after two
weeks with aphasia and right hemiparesis. Computed
tomography revealed migrated coil [Figure 1(C)] confirmed by cerebral angiography [Figure 1(D)]. The coil
was successfully retrieved using Trevo 3 mm × 20 mm
stent retriever (Stryker) [Figure 1(E) and (F), Video)
with complete recovery.
