Deep brain stimulation (DBS) has been offered to patients suffering of severe and resistant neuropsychiatric disorders like Obsessive Compulsive Disorder (OCD), Gilles de la Tourette Syndrome (TS) and Major Depression (MDD). Modulation of several targets within the cortico-striato-thalamo-cortical circuits can lead to a decrease of symptom severity in those patients. This review focuses on the recent clinical outcomes in DBS in psychiatric disorders. Studies on OCD and TS are now focusing on the long-term effects of DBS, with encouraging results regarding not only the decrease of symptoms, but also quality of life...

The history of neurosurgery is ever fascinating. The journey has been tedious, nevertheless, in the landscape of success and failures we have become more efficient and polished. Skills were learned, innovations were made, and in the process we evolved. The immense contribution of meninigioma surgery in this maturation process is attested by history itself. Countless stories exist in the literature that would testify the momentous role of meningioma in the process of evolution and reformation of neurosurgical techniques...

BACKGROUND: Surgical access to the temporal lobe is complex with many eloquent white fiber tracts, requiring careful pre-operative surgical planning. Many microsurgical approaches to the temporal lobes are described, each with their own disadvantages. The adoption of the endoscope in neurosurgery has increased the options available when treating these difficult access tumors. OBJECTIVES: We present our experience of a novel, minimally-invasive, endoscopic approach to resect temporal lobe tumors...

BACKGROUND: In recent years, simulations based on phantom models have become increasingly popular in the medical field. In the field of functional and stereotactic neurosurgery, a cranial phantom would be useful to train operative techniques, such as stereo-electroencephalography (SEEG), to establish new methods as well as to develop and modify radiological techniques. In this study, we describe the construction of a cranial phantom and show examples for it in stereotactic and functional neurosurgery and its applicability with different radiological modalities...

The medial temporal lobe can be divided in anterior, middle, and posterior segments. The anterior segment is formed by the uncus and hippocampal head, and it has extra and intraventricular structures. There are 2 main approaches to the uncohippocampal region, the anteromedial temporal lobectomy (Spencer's technique) and the transsylvian selective amygdalohippocampectomy (Yasargil's technique).In this video, we present the case of a 29-yr-old man with new onset of generalized seizures and a contrast-enhancing lesion in the left anterior segment of the medial temporal lobe compatible with high-grade glioma...

Temporal lobe epilepsy (TLE) is the most common partial complex epileptic syndrome and the least responsive to medications. Deep brain stimulation (DBS) is a promising approach when pharmacological treatment fails or neurosurgery is not recommended. Acute brain slices coupled to microelectrode arrays (MEAs) represent a valuable tool to study neuronal network interactions and their modulation by electrical stimulation. As compared to conventional extracellular recording techniques, they provide the added advantages of a greater number of observation points and a known inter-electrode distance, which allow studying the propagation path and speed of electrophysiological signals...

Post-surgical aspergillosis is an uncommon complication that carries a high mortality rate in affected patients. The diagnosis is challenging given the lack of highly sensitive methods to isolate Aspergillus from surgical sites. Here, we present a case of post-surgical aspergillosis that occurred after the resection of acoustic neuroma in an immunocompetent patient. Imaging revealed leptomeningeal enhancement and a cerebellar extra-axial fluid collection adjacent to the right retrosigmoid craniotomy. The patient was taken to the operating room for debridement, where purulent fluid was obtained from subdural space...

Cerebrovascular diseases are among the most widespread diseases in the world, which largely determine the structure of morbidity and mortality rates. Microvascular anastomosis techniques are important for revascularization surgeries on brachiocephalic and carotid arteries and complex cerebral aneurysms and even during resection of brain tumors that obstruct major cerebral arteries. Training in microvascular surgery became even more difficult with less case exposure and growth of the use of endovascular techniques...

The concept of minimally invasive neurosurgery has significantly evolved in recent years, which is associated with improvements in diagnostics, microneurosurgical techniques, anesthesiology, and intraoperative imaging. MATERIAL AND METHODS: We present the preliminary results of using transpalpebral craniotomy in surgery of supratentorial aneurysms and anterior cranial fossa tumors. In the period between 2015 and 2107, we used this approach in surgical treatment of 30 aneurysms (10 aneurysms in the 'cold' period of hemorrhage and 20 unruptured aneurysms) and 10 anterior cranial fossa base tumors...

INTRODUCTION: Sodium Fluorescein (SF) is a green, water-soluble dye with the capacity to accumulate in cerebral areas as a result of damaged blood-brain barrier (BBB); this property allows SF to concentrate specifically at the tumor site of various types of brain neoplasms, making the tumor tissue more clearly visible. EVIDENCE ACQUISITION: A literature search (1947-2018) was conducted with the keywords "fluorescein neurosurgery", "YELLOW neurosurgery", "fluorescein brain tumor", "YELLOW brain tumor"...

BACKGROUND: Mastoid emissary vein is especially important from the neurosurgical point of view, because it is located in variable number in the area of the occipitomastoid suture and it can become a source of significant bleeding in surgical approaches through the mastoid process, especially in retrosigmoid craniotomy, which is used for approaches to pathologies localized in the cerebellopontine angle. Ideal imaging method for diagnosis of these neglected structures when planning a surgical approach is high-resolution computed tomography...

Hua Gao, Chunhui Liu, Yazhuo Zhang
The endoscope has traditionally been used in neurosurgery to access a lesion within a natural body cavity. The challenge has been to access and resect deep-seated intraparenchymal lesions using a minimally invasive endoscopic technique. Endoscopic endonasal trans-sphenoidal surgery has gained increasing acceptance by otolaryngologists and neurosurgeons. Surgical procedures of the skull base include exposure, resection, and base reconstruction. These approaches start at the sphenoid sinus, which provides a reference point to important vascular and neural structures...
