Endoscopic endonasal approaches (EEA) have gained popularity and acceptance in skull base surgery over the last two decades. So-called expanded EEA allow access in the sagittal plane from the frontal sinus to the odontoid process. The endoscopic endonasal transclival approach allows a unique trajectory into the midline clivus and skull base that is unachievable from traditional craniotomy approaches to lesions such as chondrosarcomas, chordomas, and posterior fossa meningiomas. In this review, we will assess the benefits and drawbacks to using an endoscopic endonasal approach versus transcranial approach to these challenging lesions, assess the anatomical limits of endoscopic endonasal transclival surgery, and discuss the published literature on the topic...

Endoscopic endonasal access to the jugular foramen and occipital condyle-the transcondylar- transtubercular approach-is anatomically complex and requires detailed knowledge of the relative position of critical neurovascular structures, in order to avoid inadvertent injury and resultant complications. However, access to this region can be confusing as the orientation and relationships of osseous, vascular, and neural structures are very much different from traditional dorsal approaches. This review aims at providing an organizational construct for a more understandable framework in accessing the transcondylar-transtubercular window...

Stroke is one of the leading causes of mortality and morbidity worldwide and requires rapid and intensive treatment to prevent adverse outcomes. Decompressive hemicraniectomy stands as the gold standard for surgical resolution of the intracranial swelling which accompanies cerebral infarction; however, the benefits of this procedure are not as well achieved in the elderly (age >65 yoa) compared to the younger population. This is a critical review performed on all available literature relating to middle cerebral artery (MCA) stroke in the elderly with emphasis on articles examining causality of adverse outcomes in this group over younger populations...

Brain arteriovenous malformations (bAVM) are challenging lesions. Part of this challenge stems from the infinite diversity of these lesions regarding shape, location, anatomy, and physiology. This diversity has called on a variety of treatment modalities for these lesions, of which microsurgical resection prevails as the mainstay of treatment. As such, outcome prediction and managing strategy mainly rely on unraveling the nature of these complex tangles and ways each lesion responds to various therapeutic modalities...

The proximity of craniopharyngiomas to vital neurovascular structures and their high recurrence rates make them one of the most challenging brain tumors to treat. Although surgery remains the first line of therapy and offers the best chance of radical resection and oncological cure, the high recurrence tendency of craniopharyngiomas, even after apparent total removal, often makes adjuvant treatment essential. The endoscopic endonasal approach (EEA) has been recently introduced as a treatment option for both pediatric and adult craniopharyngiomas, rapidly gaining wide acceptance over the traditional transcranial approaches...

Cryptococcal meningoencephalitis is the most common infective complication observed in patients with CD4 lymphocytopenia, including sarcoidosis. T-cell immunity is well characterized in HIV-related infections and data regarding immunity in cryptococcosis animal models is now available; on the contrary, little is known about the immune status in non-HIV-related infections. We report on reduced production of new T cells observed in a patient with sarcoidosis, CD4 lymphocytopenia, and cryptococcal-related meningoencephalitis...

BACKGROUND: There is uncertainty of the benefit of preoperative embolization for Spetzler- Ponce Class (SPC) B and C arteriovenous malformations of the brain (bAVM). We examined whether or not preoperative embolization reduces the risk of permanent neurological deficits in SPC B and C bAVM surgery. METHODS: A prospective bAVM database (between1989 and 2015) was analyzed by regression for factors associated with a new permanent neurological deficit arising as a consequence of surgery or preoperative embolization with a modified Rankin Scale (mRS) score >1 at 12 months after surgery (adverse outcome)...

BACKGROUND: Unruptured intracranial aneurysms (UIAs) are increasingly identified and are an important health-care burden; in the past they were commonly treated by surgical clipping, but nowadays endovascular coil embolization is increasingly employed as an alternative. METHODS: The Unruptured Aneurysms Italian Study (UAIS) is a multicentric cooperative prospective study aimed to delineate the "State of the Art" of UIAs treatment in Italy. 51 Italian Neurosurgical and Neuroradiological Units, representatives of all 20 Italian regions are involved in the Study...

BACKGROUND: Artificial Intelligence (AI) techniques play a major role in anesthesiology, even though their importance is often overlooked. In the extant literature, AI approaches, such as Artificial Neural Networks (ANNs), have been underutilized, mainly being used to model patient's consciousness state, to predict the precise amount of anesthetic gases, the level of analgesia, or the need of anesthesiological blocks, among others. In the field of neurosurgery, ANNs have been effectively applied to the diagnosis and prognosis of cerebral tumors, seizures, low back pain, and also to the monitoring of intracranial pressure (ICP)...

BACKGROUND: Most patients with pineal cysts referred for neurosurgical consultation have no specific symptoms or objective findings except for pineal cyst size to help in management decisions. Our purpose was to assess the relationship between pineal cyst size and aqueductal CSF flow using PC-MRI. METHODS: Eleven adult patients with pineal cysts (> 1-cm in size) referred for neurosurgical consultations were included. Cyst volume was calculated using 3D T1 images...

INTRODUCTION: A fenestration is an anatomical variation that most commonly involves vessels of the posterior circulation, which can predispose the formation of aneurysms and represents a further technical challenge for treatment. There are no large series and the incidence of complications is unknown. This paper is a systematic review on this topic. EVIDENCE ACQUISITION: The relevant English literature was reviewed and the data was extracted for each patient and collected in a pool...

BACKGROUND: In surgery, the learning process represents one of the critical topics in the development of a young surgeon, where there is often no standardized learning program. The learning curve is defined by plotting proficiency as a function of time, or the number of repetitions. In this study, we have analyzed the learning process for a rare and surgically demanding pathology such as thoracic disc herniations (TDHs) treated with an antero-lateral trans-thoracic approach. METHODS: We analyzed a consecutive series of patients admitted with a diagnosis of TDHs...
