New evidence of prehistoric neurosurgery in Italy: the case of Castello del Tartaro.

Archaeological evidences of trepanation during the European Bronze Age are numerous, and testify a wide application of neurosurgical practices during Prehistory. In some particular cases, trepanations may be associated with other peculiar evidences concerning funerary practices. The aim of this paper is to present the case of a woman from the Recent Bronze Age site of Castello del Tartaro (Verona, Italy), who was buried in a prone position and whose skeletal remains presented evidences of a probable frontal...

Aqueductal CSF Stroke Volume Flow in A Rodent Model of Chronic Communicating Hydrocephalus: Establishing A Homogeneous Study Population for CSF Dynamics Exploration.

Idiopathic-normal-pressure-hydrocephalus (iNPH), is a cause of dementia that can be reversed when treated timely with CSF-diversion. CSF-dynamics understanding throughout the development of hydrocephalus is crucial to identify prognostic markers to estimate benefit/risk to shunts.

Suprasellar epidermoid cyst: case report of extended endoscopic transsphenoidal resection and systematic review of the literature.

Suprasellar epidermoid cysts (SECs) constitute a large portion of so-called pearly tumours. Despite insidious development and infiltration into vital neurovascular structures, they have friable consistency which particularly facilitates their resection, and to date the only alternative to surgery is wait-and-see policy. Herein we present a case of SEC in a patient with bitemporal hemianopia and no other significant symptom, and results of analysis of data on surgical treatment of 71 similar cases reported i...

An Unusual case of Transdural Herniation of Lumbar Intervertebral Disc: Diagnostic difficulties and surgeon experience.

Diagnosis and Endovascular Embolization of a Sacral Spinal Arteriovenous Fistula with "Holo-spinal" Venous Drainage.

Spinal dural arteriovenous fistulas are the most common spinal vascular pathology, accounting for up to 70% of spinal vascular malformations. They most commonly present with insidious and progressive myelopathy and bowel, bladder, and sexual dysfunction. Although noninvasive imaging (e.g., magnetic resonance imaging or angiography) may suggest the presence of a spinal arteriovenous fistula (AVF), the diagnosis requires confirmation with spinal angiography.

Chiari I Malformation: Opinions on Diagnostic Trends and Controversies from a panel of 63 International Experts.

Chiari I Malformation (CMI) and the topics concerning it have been the subject of numerous discussions and polarizing controversies over the course of the last 20 years. The opinions of 63 recognized international CMI experts from 4 continents, with a collective surgical experience of more than 15,000 CMI cases, were gathered through a detailed questionnaire. Three facts emerged from the analysis of the results: 1: The vast majority of the replies showed a high level of consensus on the majority of the CMI ...

Reliability analyses of radiographic measures of vertebral body height loss in thoracolumbar burst fractures.

In thoracolumbar (TL) burst fractures, vertebral body height loss (VBHL) indicates the degree of instability and constitutes one of decision criteria for surgical treatment. However, the relative reliability and variability of different measurement techniques for VBHL are unknown. We compared the reliability of different methods used to assess VBHL.

Case Report of De novo cavernous carotid artery aneurysm following an acute stroke intervention for a carotid occlusion.

and Importance: Arterial dissections are a common cause of stroke in young patients but may occur at any age. There is no previous reports of an intracranial carotid artery dissection that evolved spontaneously into both complications, i.e. stroke and pseudoaneurysm. To our knowledge this is the first case of arterial dissection complicated by an occlusion and a pseudoaneurysm occurring at the same site.

Repeated intracranial hemorrhage after delivery induced by coagulopathy associated with multiple venous malformations - Case report.

Glioblastoma presenting as spontaneous subarachnoid hemorrhage: a technical case note of combined endovascular and microsurgical vision sparing treatment.

Clinical utility of endovascular adjunct for tumor resection is well established, but its role in acute subarachnoid hemorrhage (SAH) secondary to neoplastic pseudo aneurysm rupture has not been reported. We discuss a 46-year-old patient presenting with a WFNS grade 1 SAH from a rupture posterior cerebral artery (PCA) pseudo aneurysm due to glioblastoma tumor invasion. A combined targeted endovascular embolization with microsurgical resection to spare the calcarine artery was utilized to avoid disruption to...

A single-center retrospective descriptive cohort study of 211 pediatric patients: Cerebrospinal fluid leakage after fourth ventricle tumor resection.

CSF leak remains a significant complication of posterior fossa tumor surgery.

Comparison of Haemostatic Gelatin Sponge Impregnated with Ropivacaine versus Normal Saline applied on the Transverse Process of the Operated Vertebrae on Post-Operative Pain in Patients Undergoing Spinal Instrumentation Surgery: A Randomized Clinical Trial.

Protocols for effective postoperative pain control in patients undergoing spinal surgery are not standardized. In our study, we compared the effect of haemostatic absorbable gelatin sponge impregnated with ropivacaine versus normal saline when applied to the transverse process of the operated vertebrae on the postoperative pain following instrumentation spine surgery.

Ventricular Meningiomas; Surgical Strategies and A New Finding that Suggest An Origin From The Choroid Plexus Epithelium.

Pituitary adenoma concomitant with Chiari I Malformation: Case report and literatura review.

Pituitary adenomas (PA) are usually benign neoplasms. Chiari I malformation (CIM) is an uncommon finding. Isolated cases associating functional PA and CIM have been reported. The concomitant presence of a non-functional PA and a CIM has not yet been described in the literature.

Retrosigmoid Intradural Temporal Bone Drilling for Intrapetrous Chondrosarcoma Extending to Cerebellopontine Angle.

Recently the intradural temporal bone drilling has been used in conjunction with the retrosigmoid approach to allow expanded to access to a variety of types of intraosseous invasions.Video 1 demonstrates the intradural temporal bone drilling via the retrosigmoid approach in the microsurgical removal of an intrapetrous chondrosarcoma extending to the cerebellopontine angle. The patient was a 23-year-old woman presented with progressive hearing disturbance, hemifacial spasm, and tinnitus. Neuroimaging reveale...

Multimodal Monitoring Strategy Is Decisive in Elective Middle Cerebral Artery Aneurysm Clipping: A Case Report.

The intraoperative use of neurophysiological monitoring (IONM) and indocyanine green video angiography (ICGVA) for aneurysm clipping have evolved during the last years. Both modalities are useful and safe by allowing greater rates of complete aneurysm occlusion with less intraoperative complications and postoperative neurologic deficits. We report a case of attempted aneurysm clipping in which the combined use of ICGVA and IONM was crucial for intraoperative decision-making.

Repair of Anterior Skull Base Defect by Dual-Layer/Split-Frontal Pericranial Flap.

Normal skull base structures are destroyed either by the skull base pathology itself or during surgery that results in cerebrospinal fluid (CSF) leak. Skull base repair is usually performed transnasally by using a nasal septal flap. But when NSF is not available and failed repeated transnasal repair, a cranionasal repair with frontal pericranial flap (PF) can be attempted to achieve the highest successful chance. We performed a dual layer/split PF repair of a skull base defect using cranionasal approach and...

Heterotopic Neuroglial Tissue in Sphenoid Ridge.

Extracerebral neuroglial heterotopias are rare manifestations of cerebral tissue outside the brain whose most common form is the so-called nasal glioma. In this case report we illustrate the first case of heterotopic neuroglial tissue within the bone of the skull.
