Microvascular decompression of aberrantly looped anterior inferior cerebellar artery: illustrative case

Circuitous anatomy of AICA may present particular challenges for microvascular decompression, but it is still possible to achieve a noncompressive configuration to best limit future irritation of the trigeminal nerve. An optimal and durable separation of the AICA loop and trigeminal nerve adhering to noncompressive principles was achieved using two aneurysm clips to fix a Teflon felt to the tentorium and petrous face of the temporal bone. https://thejns.org/doi/10.3171/CASE25388.
