Preoperative visualization of neurovascular contact with 3D-FIESTA combined with 3D-TOF MRA to guide microvascular decompression surgery planning
Background:Neurovascular compression syndromes including trigeminal neuralgia (TN) and hemifacial spasm (HFS) are caused by neurovascular conflicts at the root entry zone of the corresponding cranial nerves in the posterior fossa.Microvascular decompression (MVD) is the best choice for the treatment of TN and HFS.An accurate delineation of the resp
