Background: Basilar apex aneurysms constitute 5-8% of all intracranial aneurysms, and their treatment remains challenging for both microsurgical and endovascular approaches. The perceived drawback of the microsurgical approach is its invasiveness leading to increased surgical morbidity. However, many high-volume centers have shown excellent clinical results with better occlusion rates compared to endovascular treatment. With endovascular therapy taking a larger role in the management of cerebral aneurysms, the future role of microsurgery for basilar apex aneurysm treatment is unclear...

Vitreoretinal microsurgery is among the most technically challenging of the minimally invasive surgical techniques. Exceptional precision is required to operate on micron scale targets presented by the retina while also maneuvering in a tightly constrained and fragile workspace. These challenges are compounded by inherent limitations of the unassisted human hand with regard to dexterity, tremor and precision in positioning instruments. The limited human ability to visually resolve targets on the single-digit micron scale is a further limitation...

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...

OBJECTIVE: Although most intracranial aneurysms can be treated with microsurgery or endovascular procedure alone, a subset of aneurysms may require a combined approach. The purpose of this study was to assess the efficacy of endovascular interventions combined with bypass surgery for the treatment of complex intracranial aneurysms. METHODS: We retrospectively reviewed medical records from a prospectively maintained patient database to identify patients who underwent endovascular treatment of an intracranial aneurysm at our institutes from 2007 to 2017...

BACKGROUND: Transanal minimally invasive surgery (TAMIS) is considered the successor of transanal endoscopic microsurgery (TEMS). It makes use of more readily available laparoscopic instruments and single-port access platforms with similar perioperative, clinical and oncological outcomes. Little is known about quality of life (QoL) outcomes after the use of TAMIS. The aim of this study was to assess QoL after TAMIS in our patients and compare this with QoL in the healthy Dutch population...

Stereotactic radiosurgery (SRS) is frequently used for Cushing's disease (CD) after failed pituitary surgery. Management of patients with persistent CD after failed SRS is complex, as the alternative therapeutic options harbor significant risks. The outcomes of repeat pituitary radiosurgery, however, have not been described. We sought to determine the outcomes of repeat SRS in patients with CD. We pooled data from five institutions participating in the International Gamma Knife Research Foundation for patients with recurrent or persistent CD ≥ 12 months after initial SRS...

BACKGROUND: Decompressive laminectomy (DI) is a standard operation for lumbar spinal stenosis (LSS) patient with severe claudication symptoms for many years. However, patients whose symptom severity does not meet undergoing invasive surgery make therapeutic options into dilemma. Interspinous spacers (ISP) bridge the gap between surgical interventions and CC in management of LSS. In our study, we aim to systematically assess the two FDA-approved interspinous spacers for treatment of lumbar spinal stenosis: Superion versus X-STOP...

Arachnoid cysts (ACs) within the fourth ventricle are rare, and only a few cases have been reported in the literature. These are benign lesions within the arachnoid membrane, and they have been reported to occur in almost all locations where arachnoid is present. Different procedures have been performed to restore a normal cerebrospinal fluid dynamic and/or pressure, including shunting and partial or complete excision of the cyst by open microsurgery or endoscopic fenestration. We report the case of a fourth ventricle AC successfully treated using only endoscopic anterior trans-frontal cyst fenestration/marsupialization and standard third ventriculostomy...

Time-lapse in vivo microscopy studies of cellular morphology and physiology are crucial toward understanding brain function but have been infeasible in the fruit fly, a key model species. Here we use laser microsurgery to create a chronic fly preparation for repeated imaging of neural architecture and dynamics for up to 50 days. In fly mushroom body neurons, we track axonal boutons for 10 days and record odor-evoked calcium transients over 7 weeks. Further, by using voltage imaging to resolve individual action potentials, we monitor spiking plasticity in dopamine neurons of flies undergoing mechanical stress...
