1
AICA aneurysms are rare and often present with subarachnoid hemorrhage, complicating surgical reconstruction due to their morphology and location.
-
2
Endovascular parent artery occlusion (PAO) is often necessary for treating ruptured AICA aneurysms, despite risks to the internal auditory artery (IAA).
-
3
A 64-year-old male patient experienced facial palsy and hearing loss after ePAO of a ruptured AICA aneurysm, indicating potential complications.
-
4
Postoperative recovery included improved facial function and hearing, with significant recovery noted by day 50, despite initial deficits.
-
5
This case suggests that neurologic recovery is possible after IAA occlusion, challenging the notion that such deficits are permanent.
