This video shows an exoscope-guided single-stage resection with 3-dimensional technology of a supratentorial cavernoma and a supratentorial hemangioblastoma during the same surgical procedure. The patient is a 42-yr-old man with a history of generalized tonico-clonic seizures. Contrast-enhanced magnetic resonance (MR) revealed the presence of a left frontal cavernoma and a left T1 non-enhancing hypointese temporal lesion (hemangioblastoma). The operation was carried out in the lateral position with the sole use of a 3D-exoscope (VITOM-3D, Karl Storz GmbH&Co, Tuttlingen, Germany)...

Intracerebral hemorrhage (ICH) with or without intraventricular hemorrhage (IVH) is a highly morbid disease process due to the mass effect and secondary injury that occurs upon the surrounding brain. Historically, surgical evacuation has failed to demonstrate improved outcomes in comparison to standard medical therapy likely due to the significant brain trauma when accessing the clot. Recent minimally invasive techniques have proposed a way to improve outcomes by reducing this injury. We report here a 62-year-old male with ICH and IVH with acute neurological deterioration due to hydrocephalus was found to have no improvement following external ventricular drainage...

Deep-seated, subcortical tumors represent a surgical challenge. The traditional approach to these lesions involve large craniotomies, fixed retractor systems, and extensive white matter dissection, each with their own associated morbidity. We describe our experience with the use of tubular retractors for accessing these deep-seated lesions. Fifty consecutive patients operated on for an intra-axial brain tumor (both biopsies and resection) from January 2016 to December 2017 by a single surgeon using tubular retractors with exoscopic visualization were prospectively identified and included in this consecutive case series...

The ideal visualization tools in microneurosurgery should provide magnification, illumination, wide fields of view, ergonomics, and unobstructed access to the surgical field. The operative microscope was the predominant innovation in modern neurosurgery. Recently, a high-definition three-dimensional (3D) exoscope was developed. We describe the first applications in pediatric neurosurgery. The VITOM 3D exoscope (Karl Storz GmbH, Tuttlingen, Germany) was used in pediatric microneurosurgical operations, along with an OPMI PENTERO operative microscope (Carl Zeiss AG, Jena, Germany)...
