  • Title: Left Interhemispheric Craniotomy for Resection of Cavernous Malformation: 2-Dimensional Operative Video.
    Author: Hendricks BK, Spetzler RF.
    Journal: Oper Neurosurg (Hagerstown); 2019 Oct 01; 17(4):E154. PubMed ID: 31529133.
    Abstract:
    Thalamic cavernous malformations pose variable surgical challenges given that the location and size of the lesion often determine the approach surgical trajectory. The patient in this case has a large thalamic cavernous malformation that results in a mass effect on the third ventricle and directly abuts the lateral ventricle. A small interhemispheric craniotomy is performed to allow for an anterior interhemispheric transcallosal approach to the lesion. The lateral ventricle is accessed, and the septum is removed to enhance visualization of the surgical field. A small rim of normal parenchyma on the lateral margin of the thalamus is transgressed, and the cavernous malformation is entered. The lesion is removed in a piecemeal manner. Use of counter traction assists with the piecemeal removal. The lighted suction is critical during inspection and manipulation of the lesion within the resection cavity given the limited lighting deep within the cavity. The lesion was removed completely, and postoperative imaging confirms gross total resection. The patient gave informed consent for surgery and video recording. The institutional review board approval was deemed unnecessary. Used with permission from the Barrow Neurological Institute.
