Objective:
We report two patients with unruptured large aneurysms treated by overlapping stent-assisted coil embolization using low-profile visualized intraluminal support (LVIS) stents.
Case Presentation:
Case 1: An 80-year-old woman presented with abducens nerve palsy due to an internal carotid artery aneurysm. Case 2: A 75-year-old man presented with a partially thrombosed fusiform aneurysm in the vertebral artery (VA). Both patients were treated by overlapping LVIS stent-assisted coil embolization (overlapping LSACE). Digital subtraction angiography (DSA) a few months after embolization demonstrated complete occlusion of the aneurysm, although immediate angiography revealed dome filling.
Conclusion:
Overlapping LSACE may be an effective treatment method for aneurysms that are difficult to treat by standard SACE and result in better flow-diverting effects.
