Abstract

Objective: We report a patient in whom vascular straightening was achieved after stent-assisted coil embolization, leading to complete occlusion of an intracranial aneurysm after 1 year.

Case Presentation: The patient was a 60-year-old female. A medical checkup of the brain showed a posterior inferior cerebellar artery (PICA) aneurysm. Under general anesthesia, coil embolization was performed. During surgery, a coil deviated onto the PICA side, and a stent was deployed so that the aneurysmal neck might be located at its center. Finally, incomplete occlusion of the aneurysm was achieved. Cerebral angiography 1 year after surgery indicated a sharper branching angle of the blood vessel in comparison with the preoperative angle and complete occlusion of the aneurysm.

Conclusion: A braided stent inserted to a site where a thin parent vessel is not fixed by the peripheral structure may make the parent vessel straight, contributing to complete occlusion of an aneurysm.
