OBJECTIVE Advances in video and fiber optics since the 1990s have led to the development of several commercially available high-definition neuroendoscopes. This technological improvement, however, has been surpassed by the smartphone revolution. With the increasing integration of smartphone technology into medical care, the introduction of these high-quality computerized communication devices with built-in digital cameras offers new possibilities in neuroendoscopy. The aim of this study was to investigate the usefulness of smartphone-endoscope integration in performing different types of minimally invasive neurosurgery...

BACKGROUND: Posttraumatic hydrocephalus (PTH) and posthemorrhagic hydrocephalus (PHH) were previously considered not suitable for neuroendoscopic treatment. New hydrocephalus theories support possible successful neuroendoscopy in such patients. METHODS: This study presents the results of neuroendoscopy in PTH and PHH with a background analysis. From 130 hydrocephalic patients after neuroendoscopic surgeries, 35 cases with PTH (11 patients) or PHH (24 patients - 9 acute, 10 subacute, 5 chronic) were found...

The postoperative ventricular adhesion after resection of CNS tumors may obstruct physiological CSF circulation and cause temporal horn entrapment. The surgical goal is to restore physiological flow of cerebrospinal fluid (CSF). The authors reviewed their database to report their experience with endoscopic fenestration for treating entrapped temporal horn caused by atrial adhesions. All endoscopic operations performed from February 2015 to December 2016 were reviewed. Three patients developed temporal horn entrapment after tumor resection...

BACKGROUND: Ventriculoperitoneal (VP) shunt is the most frequent treatment for hydrocephalus. VP shunt malfunction is a very common problem in neurosurgical practice, often requiring shunt revision procedures. In some cases, complete removal of a VP shunt may present difficulties, leading the surgeon to leave the ventricular catheter in situ. This decision is often made to avoid possible adverse events, primarily risk of life-threatening hemorrhage. However, a nonfunctioning catheter left in the ventricular system 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...

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, describe our clear-cut surgical technique, and analyze results in the context of literature data. METHODS: We reviewed the clinical data of 8 consecutive adult patients affected by cystic or mixed craniopharyngioma who 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...
