Staged Y-shaped Stent Assisted Coil Embolization in a Wide-Neck Basilar Tip Aneurysm: Case Report / 신경중재치료의학

ABSTRACT

A 67-year-old male presented with a subarachnoid hemorrhage and was found to have a basilar artery (BA) tip aneurysm, which was incorporated to both posterior cerebral arteries (PCAs). First, he was treated with the single stent, which was deployed from P1 segment of the right PCA to BA, and coil embolization was done. Follow-up angiogram at 18 months revealed coil compaction of the aneurysm. Therefore, we accomplished the Y-configured dual stent assisted coil embolization. Follow-up angiogram at 30 months revealed no recanalization of aneurysm and patent blood flow of both PCAs. In conclusion, staged Y-shaped stents assisted coil embolization is an alternative treatment option in a wide-neck basilar tip aneurysm decreasing the extent of coil compaction of aneurysm and preserving an incorporated vessel.
