Objective: We report a case of ruptured anterior communicating artery aneurysm in which residual aneurysm after coil embolization could be completely occluded by LVIS Jr. stent placement.

Case Presentation: A 73-year-old woman underwent coil embolization in the acute phase of ruptured anterior communicating artery aneurysm. Since the parent artery was narrow with a diameter of 1 mm, and since the bifurcation angle of the A1 segment was sharp, manipulation of the microcatheter was difficult, and the treatment was terminated after partial embolization. After 40 days, retreatment was performed by LVIS Jr. stent placement. No intra- or postprocedural complication was observed, and complete occlusion of the aneurysm was confirmed by angiography after 3 months.

Conclusion: Complete occlusion of the residual aneurysm could be achieved due to the flow diversion effect of LVIS Jr. stent. This procedure can be an option in retreatment.
