A 69-year-old female patient presented with a ruptured small basilar apex aneurysm. Balloon-assisted coil embolization was performed, and the patient remained stable post-operatively. A CT-scan performed 12 days after the procedure showed coil migration from the aneurysm, and repeat angiography confirmed coil migration into the left proximal posterior cerebral artery segment. The patient gave consent for a revision procedure, where an LVIS Jr. stent and 7 micro-coils were placed into the aneurysm to re-secure the aneurysm. The patient suffered no further complications and was discharged home on dual antiplatelet therapy. Modified Rankin Score at 90-days was 1. We review the literature regarding delayed coil migration, and discuss management considerations.
