title: Utilisation of intra-operative Doppler in the localisation of pericallosal artery during functional hemispherotomies for epilepsy: technical note.
abstract: Functional hemispherotomy is an established technique for treating epilepsy secondary to hemispheric pathology. Corpus callosotomy and frontobasal disconnection are integral parts of this operation. To perform this, localisation of the pericallosal artery through the medial ventricular wall and subpial exposure of the A2 and A1 are required. Here, the authors present how intra-operative Doppler can be useful in helping to localise these arteries in the setting of abnormal neuroanatomy and significant brain shift.
