A Case of Suspected Dissecting Anterior Communicating Artery Aneurysm Treated with Parallel Stent-assisted Coiling

Abstract

Objective: We report a rare case of a suspected dissecting aneurysm of the anterior communicating artery (ACoA) from intraoperative findings who underwent endovascular internal trapping using a parallel stent-assisted technique for bilateral anterior cerebral arteries.

Case Presentations: A 21 year-old male presented with a subarachnoid hemorrhage. Emergent neck clipping failed due to difficulty in hemostasis, indicating dissection of ACoA. Parallel stent-assisted internal trapping was performed on the following day. Even though he recovered well without re-rupture, additional embolization was required fourteen days later because of recanalization on the follow-up angiography.

Conclusion: This is the first report of parallel stenting for internal trapping of ACoA to the best of our knowledge; however, careful follow-up is necessary for a dissecting aneurysm is suspected.
