BACKGROUND: Ventricular tumors represent a major neurosurgical challenge, making endoscopic approach an invaluable tool as it gained importance due to technological advances. Nevertheless, the method is not exempt of risk and limitations, sometimes requiring an open surgery. Thus, initial measurements must be adopted in order to simplify an eventual need for conversion to open craniotomy. METHODS: Here, we describe a series of 6 patients with ventricular tumors approached by neuroendoscopy where the conversion to microsurgery turned out to be necessary...

Surgical resection of petroclival meningiomas remains challenging due to their deep location and relationship to vital neurovascular structures. Although the natural history of these tumors involves a slow course, the incidence of cranial nerve deficits and the extent of tumor resection vary widely in the literature. Some reviews on this topic have been conducted, but data remain fragmentary and based on retrospective case series, which hinders attempts at meta-analysis. Within this context, research into the use of minimally invasive approaches, including in neuroendoscopy, continues to emerge...

BACKGROUND: Among the rare intraventricular cavernomas (IVCs), purely intraaqueductal cavernomas are exceptional. CASE DESCRIPTION: We report a unique case of a 62-year-old patient who presented to our clinics complaining of progressive headache, memory loss, gait instability, and urinary incontinence. MR imaging showed the presence of a mass lesion located in the lumen of the cerebral aqueduct, associated with triventricular hydrocephalus. CONCLUSIONS: We discuss the rationale that led us to treat hydrocephalus with neuroendoscopy, which offered the possibility to directly inspect the intraaqueductal lesion, make the diagnosis of cavernoma, and treat symptoms due to hydrocephalus without increasing the risk of bleeding...

A 70-year-old man presented to our hospital because of difficulty with discrete movement of the right upper limb and dysarthria. Computed tomography(CT)of the head revealed a chronic subdural hematoma(CSDH)on the left side. The patient underwent single burr-hole irrigation and drainage on the same day. In addition to the burr hole, a cross-shaped dural incision was made which revealed a thick outer membrane and solidified hematoma. We removed as much of the clotted hematoma as possible using a curved suction tube under neuroendoscopy...

BACKGROUND: Use of traditional two-dimensional (2-D) neuroendoscopy is limited by lack of depth perception. The advent of next-generation three-dimensional (3-D) endoscopes potentially compensates for this limitation. The aim of this study was to objectively compare the 2 modalities in a controlled laboratory environment. METHODS: Using 2-D and 3-D endoscopes, 8 participants performed simple and complex motor tasks. Participants were divided into 3 groups: novice (n = 3), beginner (n = 4), and expert (n = 1), based on prior neuroendoscopy training...

Symptomatic intracranial arachnoid cysts are commonly treated using neuroendoscopy. Cysts located within the posterior fossa may present a greater surgical challenge to the neurosurgeon due to the numerous vital neurovascular structures located within this confined space. Adding neuronavigation during endoscopy helps a neurosurgeon to visualize and utilize both anterior and posterior corridors safely to access and manage these lesions. We present three symptomatic posterior fossa arachnoid cysts that were treated successfully using minimally invasive neuronavigation-guided endoscopic neurosurgery utilizing the anterior transfrontal transaqueductal, anterior transfrontal transtrigonal, and posterior suboccipital infratentorial supracerebellar approaches...

OBJECTIVE: Cerebrospinal fluid shunting can effectively lower intracranial pressure and improve the symptoms of idiopathic intracranial hypertension (IIH). Placement of ventriculoperitoneal (VP) shunts in this patient population can often be difficult due to the small size of the ventricular system. Intraoperative adjuvant techniques can be used to improve the accuracy and safety of VP shunts for these patients. The purpose of this study was to analyze the efficacy of some of these techniques, including the use of intraoperative CT (iCT) and frameless stereotaxy, in optimizing postoperative ventricular catheter placement...
