In neurosurgery, brain biopsy is an essential tool for providing adequate histological sampling in neoplastic and non-tumorous lesions. There are two main techniques in obtaining tissue samples: open biopsy requiring craniotomy or needle biopsy. Needle biopsies allow for minimally-invasive tissue diagnosis with less risk of operative morbidity for the patient. This video article show a frameless needle biopsy of a cerebellar lesion using the Brainlab varioguide system.

This video outlines the surgical steps involved in the microsurgical resection of an intracranial dural arteriovenous fistula (dAVF) in a 74-year-old male patient, highlighting the importance of meticulous planning, intraoperative imaging, and precise dissection techniques. The patient has previously undergone embolization, but recurrence occurred despite the initial treatment, and patient symptoms liked headaches and weakness restarted. A decision was made to perform microsurgical resection of dAVF. The video provides a comprehensive illustration of this procedure, emphasizing the value of microsurgery as a definitive treatment modality for these challenging clinical scenarios.

This is a case of a 49-year-old patient who presented with persistent headaches with no focal neurologic deficit. An MRI was performed which revealed an intraventricular tumor. The lesion was seen entering the third ventricle and potentially compressing both foramina of Monro. This was further confirmed through coronal reconstruction. The proposed method for tumor removal is an interhemispheric, transcallosal approach.

Central nervous system (CNS) tumors, such as this, are uncommon neoplasms that often present with symptoms like headache, nausea, vomiting, ataxia, vertigo, and papilledema. There is also the possibility of hydrocephalus, as the tumor can obstruct cerebrospinal fluid (CSF) outflow, and the development of seizures. These tumors often grow slowly and can be managed with surgical resection, chemotherapy, and/or stereotactic radiosurgery. For intraventricular tumor resection, the surgical approach can vary based on the tumor location, experience, and preference of the surgeon.

A patient suffering from an AV fistula fed by the external carotid artery, who has failed occlusion via embolization, is being operated on by Dr. Czabanka to definitively treat the fistula. With the help of CT navigation and ICG angiography, Dr. Czabanka is able to microscopically devascularize the problematic malformation.

Watch as Dr. Czabanka navigates delicate territory to expose and excise a meningioma from the sphenoid wing of a symptomatic patient. Use of the microscope becomes crucial to prevent damage to healthy tissue while devascularizing the tumor.
