Treatment of Acute Traumatic Central Cord Syndrome: A Study of North American Trauma Centers.

Background And Objectives: Central cord syndrome (CCS) is expected to become the most common traumatic spinal cord injury, yet its optimal management remains unclear. This study aimed to evaluate variability in nonoperative vs operative treatment for CCS between trauma centers in the American College of Surgeons Trauma Quality Improvement Program, identify patient- and hospital-level factors associated with treatment, and determine the association of treatment with outcomes.

Methods: Adults with CCS were identified from the Trauma Quality Improvement Program database (2014-2016).

Isolated Traumatic Subarachnoid Hemorrhage: An Evaluation of Critical Care Unit Admission Practices and Outcomes From a North American Perspective.

Objectives: Traumatic subarachnoid hemorrhage is a common radiographic finding associated with traumatic brain injury. The objective of this investigation is to evaluate the association between hospital-level ICU admission practices and clinically important outcomes for patients with isolated traumatic subarachnoid hemorrhage and mild clinical traumatic brain injury.

Design: Multicenter observational cohort.

Spinal intraoperative three-dimensional navigation: correlation between clinical and absolute engineering accuracy.

Background Context: Spinal intraoperative computer-assisted navigation (CAN) may guide pedicle screw placement. Computer-assisted navigation techniques have been reported to reduce pedicle screw breach rates across all spinal levels. However, definitions of screw breach vary widely across studies, if reported at all.

Vertebral compression fracture (VCF) after spine stereotactic body radiation therapy (SBRT): analysis of predictive factors.

Purpose: Vertebral compression fractures (VCFs) are increasingly observed after spine stereotactic body radiation therapy (SBRT). The aim of this study was to determine the risk of VCF after spine SBRT and identify clinical and dosimetric factors predictive for VCF. The analysis incorporated the recently described Spinal Instability Neoplastic Score (SINS) criteria.

A multicenter registry of hydrocephalus following coil embolization of unruptured aneurysms: which patients are at risk and why it occurs.

Introduction: Unexplained post-procedural events such as cerebral edema, inflammation, aseptic meningitis and hydrocephalus have been reported following unruptured cerebral aneurysm coiling. However, understanding of the etiology for these occurrences is limited due to their rare occurrence. A multicenter registry was developed to investigate further the occurrence of these events.

Endovascular therapy of hypoglossal canal AVFs presenting with orbital symptoms.

Objective: Dural arteriovenous fistulae (DAVF) of the hypoglossal canal region are rare lesions. We describe three cases of DAVF of the hypoglossal canal presenting with ocular symptoms and discuss the endovascular management options.

Methods: Three consecutive patients with DAVF of the hypoglossal canal region presented with proptosis, chemosis and disturbances of extra-ocular mobility.

Intraoperative biplanar rotational angiography during neurovascular surgery. Technical note.

Object: The purpose of this study was to evaluate the authors' initial experience with the integration of high-resolution rotational and biplanar angiography during neurovascular operative procedures.

Methods: Eight patients with intracerebral arteriovenous malformations (AVMs) and aneurysms underwent surgical treatment of their lesions in a combined endovascular surgical suite. After initial head positioning, preoperative biplane and rotational angiography was performed.

Overview of the current role of endovascular and surgical treatment in spinal dural arteriovenous fistulas.

Dural arteriovenous fistulas are the most common vascular malformations of the spinal cord. These benign vascular lesions are considered straightforward targets of surgical treatment and possibly endovascular embolization, but the outcome in these cases depends mainly on the extent of clinical dysfunction at the time of the diagnosis. A timely diagnosis is an equally important factor, with early treatment regardless of the type more likely to yield significant improvements in neurological functioning.

Pituitary adenoma associated with intraventricular meningioma: case report.

Although rare, the association of intracranial meningiomas and pituitary adenomas has been reported. Intraventricular meningiomas are unusual, and meningiomas located in the fourth ventricle are even more so. We report a patient who harbored a prolactin-secreting pituitary adenoma and a fourth ventricle meningioma who was treated with surgical resection of the latter and medical treatment for the former.

Repeated meningitis as a delayed complication of scoliosis surgery.

Study Design: Case report.

Objective: To report a case of very delayed repeated meningitis after surgical treatment of scoliosis.

Summary Of Background Data: Delayed infection after spine surgery is a well-reported phenomenon, presenting usually with local wound symptoms and back pain.

Symptomatic non-atherosclerotic bilateral extracranial vertebral artery occlusion treated with extracranial to intracranial bypass: case report.

Posterior fossa ischemia is not a very frequent situation. It is responsible for about 25% of all ischemic strokes, and the vast majority of the cases are related to atherosclerotic stenosis of the vertebral and/or basilar arteries. Acute ischemia can also occur in the setting of vertebral artery dissection, traumatic or spontaneous.

Unruptured intracranial aneurysms: natural history and management decisions.

Aneurysmal subarachnoid hemorrhage (SAH) carries a grim prognosis, with high mortality and morbidity rates. The mortality rate in the first 30 days postrupture is estimated to be in the range of 40 to 50%, and almost half of the survivors will be left with a neurological deficit. Unlike patients with aneurysmal SAH, those with unruptured intracranial aneurysms usually experience no neurological deficit, and their treatment is prophylactic, aiming to reduce the risk of future bleeding and its consequences.

Traumatic bilateral intraorbital (subperiosteal) hematoma associated with epidural hematoma: case report.

Extradural hematoma (EDH) is a frequent lesion, with an incidence varying from 0.2 to 6% in patients admitted to hospital due to traumatic head injury. The higher incidence is found in patients with more severe injuries.

Cauda equina hemangioblastoma: case report.

Hemangioblastomas of the spinal cord are rare lesions, and those located at the cauda equina are even rarer. Most commonly these tumors are present in patients with von Hippel-Lindau (VHL) syndrome. We describe here the case of a 48 years old woman with a pure radicular hemangioblastoma, not associated with VHL, presenting with radicular pain, diagnosed with magnetic ressonance imaging (MRI) and submitted to total resection with a very good outcome.

[Meningioma with rhabdoid transformation: case report].

Meningiomas represent aproximatelly 30% of all intracranial tumors in autopsy studies. With an incidence of 2.3 per 100000, they are considered commom tumors in clinical practice.
