Objective: We report a case of ruptured aneurysm at the anterior pontine segment of the anterior inferior cerebellar artery (AICA) which re-ruptured after stent placement and was treated by overlapping stenting.
Case Presentation: A 53-year-old woman presented with headache. CT demonstrated subarachnoid hemorrhage. DSA revealed no evident source of bleeding. On day 10, she complained of sudden headache and CT demonstrated re-bleeding. On repeated DSA, an aneurysm at the anterior pontine segment of the right AICA was found. An LVIS Jr. stent was deployed at the right AICA including the aneurysm. On postoperative day 23, the aneurysm ruptured again. Another LVIS Jr. stent was deployed at the same area. On day 56, she was discharged home without neurological deficit.
Conclusion: Intracranial aneurysms not indicated for coil embolization or parent artery occlusion are difficult to treat. Overlapping stenting may be a treatment option for such aneurysms.
