Cavernous malformations of the third ventricle are uncommon vascular lesions. Evidence suggests that cavernous malformations in this location might have a more aggressive natural history due to their risk of intraventricular hemorrhage and hydrocephalus.1 The gold standard of treatment is considered to be microsurgical gross total resection of the lesion. However, with progressive improvement in endoscopic capabilities, several authors have recently advocated for the role of minimally-invasive neuroendoscopy for resecting intraventricular cavernous malformations...

Subdural fluid collections are frequently encountered in young children after non-accidental injury. In a subset of patients, these collections progress in size and ultimately require permanent drainage, which is commonly achieved with subdural-peritoneal shunts. However, excessive protein and cellular contents in the fluid are potential risk factors for shunt failure. Here, we describe the adaptation of an endoscopic lavage technique established for ventricular endoscopy with the aim of improving fluid condition prior to shunting...

RATIONALE: Basal ganglia hematomas resulting from the rupture of aneurysms of the distal middle cerebral artery (MCA) are extremely rare and are usually treated by craniotomy. To date, only 5 cases of MCA aneurysm have been treated using neuroendoscopy, and none of these cases involved hematomas. For the first time, we report a special case in which neuroendoscopy was used to evacuate a hematoma and clip an aneurysm at the same time. PATIENT CONCERNS: A massive basal ganglia hematoma in a 60-year-old man was evacuated using neuroendoscopy, and a distal MCA aneurysm was discovered and clipped successfully under the neuroendoscopy during the operation...

Microsurgery remains the gold standard treatment for intraventricular lesions, but it is not without limitations. The cerebral ventricles approach is considered a challenge for neurosurgeons because of their deep location and their intimate association with critical areas of the brain. It has been shown that direct endoscopic view is superior to magnetic resonance imaging (MRI) in identifying intraventricular structures and lesions. Also, during neuroendoscopy, there is no cerebrospinal fluid leak causing brain collapse as seen in microsurgery...

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 (n = 11) or PHH (n = 24; acute: n = 9, subacute: n = 10, chronic: n = 5) were found...

BACKGROUND: Hydrocephalus remains an important aspect of neurosurgical care and in select circumstances, the endoscopic third ventriculostomy (ETV) continues to remain an important treatment. In our initial experience of ETV using the commercially available plastic ventricular ports we found them both restrictive and expensive. Following this experience, we developed a stainless steel ventricular access port (VAP). We present our novel method of access involving this non-disposable ventricular port...

Continuous irrigation is an important adjunct for successful intraventricular endoscopy, particularly for complex cases. It allows better visualization by washing out blood and debris, improves navigation by expanding the ventricles, and assists with tissue dissection. A method of irrigation delivery using a centrifugal pump designed originally for cardiac surgery is presented. The BioMedicus centrifugal pump has the desirable ability to deliver a continuous laminar flow of fluid that excludes air from the system...

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...

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...

Neurovascular surgery is a broad and challenging, yet exciting field within neurologic surgery. The neurovascular surgeon must be meticulous; because the brain and spinal cord are unforgiving to ischemic insults. Along with the pressures of this demanding subspecialty comes the potential to help patients recover from potentially devastating pathology to go on and lead normal, healthy lives. Several intraoperative imaging modalities are available to help maximize treatment success while reducing risk. This article reviews each of these modalities, including digital subtraction angiography, fluorescence angiography, Doppler ultrasonography, laser Doppler, laser speckle contrast imaging, neuronavigation, and neuroendoscopy...
