Dimitrios Paraskevopoulos, Shlomi Constantini, Jarnail Bal, Jonathan Roth
BACKGROUND: Following a prior systematic review of currently available endoscope holders (EH), we aspired to detect trends, task-specific preferences and pitfalls of EH in various cranial neuroendoscopic procedures. METHODS: A questionnaire was disseminated to members of the International Federation of Neuroendoscopy (IFNE). The questionnaire evaluated indications and pitfalls of EH in different applications, in particular, differentiating between intraventricular and skull base endoscopy, as well as sub-categories of these two main fields...

During the past few decades, Chinese endoscopic neurosurgery has achieved rapid development that has been synchronous with the rest of the world. The development history of Chinese endoscopic neurosurgery can be divided into three stages as follows: cognition and initial stage (1964-1995), exploration and maturity stage (1995-2006) and rapid development and promotion stage (2006-present). In the first stage, we mainly began to become aware of endoscopic neurosurgery from the translation and review of foreign literature...

BACKGROUND: Ventriculo-peritoneal (VP) shunt is the most frequent treatment for hydrocephalus. Its malfunctioning represents one of the most common problem in neurosurgical practice, often requiring shunt revision procedures. In some cases, the complete removal of a VP shunt may present difficulties, leading the surgeon to leave the ventricular catheter in situ. This decision is often taken in order to avoid possible adverse events, first of all, life-threatening hemorrhagic risks. However, a non-functioning catheter left in the ventricular system represents a prosthetic device which may lead to further complications...

Flexible endoscopes have both a wide range of movement and a wide field of view and are thus widely used for endoscopic third ventriculostomy and biopsy. However, tumor resection using flexible endoscopes has scarcely been reported, likely owing to their single port, which has a diameter of 1.2-2.0 mm. Furthermore, flexible endoscopes do not allow some of the basic neurosurgical manipulations, especially sharp dissection with counter tension. Additionally, the position of the forceps and coagulators is fixed within the endoscope...

William E Butler, Pankaj K Agarwalla, Patrick Codd
The ventricles of the brain remain perhaps the largest anatomic structure in the human body without established primary purpose, even though their existence has been known at least since described by Aristotle. We hypothesize that the ventricles help match a stroke volume of arterial blood that arrives into the rigid cranium with an equivalent volume of ejected venous blood by spatially configuring cerebrospinal fluid (CSF) to act as a low viscosity relay medium for arteriovenous pulse wave (PW) phase coupling...

BACKGROUND: Total removal of craniopharyngiomas is burdened by high morbidity. In cases of a cystic or mixed craniopharyngioma, when the symptoms are caused by the cystic component of the tumor, a less invasive surgical approach aiming at cyst drainage may be recommended. Here we report our experience with intraventricular neuroendoscopy, describing our clear-cut surgical technique, and analyzing results in the context of literature data. METHODS: We reviewed the clinical data of 8 consecutive adult patients affected by cystic or mixed craniopharyngioma that were treated with intraventricular neuroendoscopy at our Institution in the last decade...

PURPOSE: Massive hemorrhages pose a significant problem in intraventricular endoscopic surgeries. These hemorrhages have the potential to cause mortality and morbidity, particularly in excisional surgeries. Often, the bleeding can be controlled only by cauterization and liquid irrigation, due to the incongruity of the use of antihemorrhagic agents in the fluid. The final option to stop the massive bleeding is the dry-field maneuver. In this study, the effects and clinical results of the dry-field maneuver in bleeding control of a massive bleeding were investigated...

BACKGROUND: The subependymal vascularization of the cerebral ventricles has been described in anatomical studies on human specimens. Its identification in vivo during neuroendoscopic navigation could have anatomical interest and may lead to a safer ventricular navigation, also avoiding unexpected bleeding. The traditional endoscopic visualization allows the certain identification of only the main vessels. In this study we describe the features of the subependymal vascular network (SEVN) enhanced by sodium fluorescein (SF) angiography...

Pyogenic ventriculitis is a rare but severe post-neurosurgical complication. The infection is often resistant to antibiotic treatment alone. Continuous intraventricular irrigation has been suggested but the technique is cumbersome, increases the risk for secondary infection, and is inadequate in removing adherent purulence. We used a novel neuroendoscopic approach assisted with a side-cutting aspiration device to treat four cases of post-neurosurgical pyogenic ventriculitis. Ventricular empyema was cleared in all patients and three of the four patients had favorable outcomes...

The Myriad is an innovative, high precision tool for tumor resection, designed to work within narrow endoscopic corridors. Due to its application in technically demanding situations, the learning curve associated with its use might be extremely challenging and time-consuming.The authors describe the application of an already validated training model, the skull base injectable tumor model (ITM), to allow trainees to practice with the use of the Myriad during endoscopic skull base procedures.A formalin embalmed cadaveric head was used for technical assessment...

Neurosurgeons performing intracerebral hemorrhage evacuation procedures have limited options for monitoring hematoma evacuation and assessing residual hematoma burden intraoperatively. Here, we report the successful neuroendoscopic adaptation of intravascular ultrasound, referred to here as intracavitary ultrasound (ICARUS), in two patients. Pre-evacuation ICARUS demonstrated dense hematomas in both patients. Post-evacuation ICARUS in patient 1 demonstrated significant reduction in clot burden and two focal hyperechoic regions consistent with pockets of hematoma not previously seen with the endoscope or burr hole ultrasound...

BACKGROUND: Endoscopy has gained a crucial role in high specialty neurosurgery during the last decades. At present, there are well-defined flexible neuroendoscopic procedures to treat ventricular and subarachnoid space pathologies. Neurocysticercosis is recognized as a common cause of neurologic disease in developing countries and the United States. Surgical intervention, especially cerebrospinal fluid diversion, is the key for management of hydrocephalus. In 2002, a consensus suggested that ventricular forms should be treated with endoscopy as the first option...

Neuroendoscopical images of fluid-filled cavity walls within encephalic tumours in thirteen adult patients were correlated with histopathology results of samples harvested during surgery. Extensive vascular proliferation, with mesh-like formations in a 3D pattern, as well as onionskin appearance, were observed in malignant tumours, as opposed to normal or slightly increased vascular pattern, observed in benign neoplasms. Medical facilities lacking sufficient technical resources where limited pathologist experience is expected, and can be associated with intraoperative histological misdiagnosis...

OBJECTIVE Combined endoscopic third ventriculostomy (ETC) and choroid plexus cauterization (CPC)-ETV/CPC- is being investigated to increase the rate of shunt independence in infants with hydrocephalus. The degree of CPC necessary to achieve improved rates of shunt independence is currently unknown. METHODS Using data from a single-center, retrospective, observational cohort study involving patients who underwent ETV/CPC for treatment of infantile hydrocephalus, comparative statistical analyses were performed to detect a difference in need for subsequent CSF diversion procedure in patients undergoing partial CPC (describes unilateral CPC or bilateral CPC that only extended from the foramen of Monro [FM] to the atrium on one side) or subtotal CPC (describes CPC extending from the FM to the posterior temporal horn bilaterally) using a rigid neuroendoscope...

Here we review the technical aspects of our experience with the neuroendoscopic bilateral nostril (binostril) transsphenoidal approach for pituitary adenomas. A total of 42 patients were treated in our hospital from September 2013 to December 2015. Total tumor resection was completed in 31 cases, nearly full resection was achieved in 9 cases, and partial resection was achieved in 2 cases. In most cases clinical symptoms were relieved after surgery. These included 18/22 cases with visual field and vision disorders; 19/25 cases with headaches; 11/15 cases where high baseline PRL returned to normal levels; 6/7 cases where elevated blood GH returned to normal levels; and 2/3 cases where elevated blood ACTH returned to normal levels after surgery...

Dementia is known to be induced by vascular dementia and certain neurodegenerative diseases. The presenting features of disordered memory, intellect and personality often result in referral to a neurologist initially. Septum pellucidum cyst (SPC) is a rare clinical finding and defined as a cystic structure between the lateral ventricles. SPC induced memory disorder and dementia has been seldom reported in which the clinical features are atypical and can be misdiagnosed. The main difficulty is to establish a correlation between symptoms and the cyst...
