Bilateral vertebral artery occlusion after traumatic complete disruption of the cervical spine associated with ankylosing spondylitis.

Bilateral vertebral artery occlusion is an uncommon and mortal injury that could be seen after high-energy traumas. We illustrate an extreme case of bilateral vertebral artery occlusion following traumatic cervical disruption with complete spinal cord injury in a patient with ankylosing spondylitis. A 49-year-old male was admitted to our emergency department after a motor vehicle accident.

Efficiency of Distraction and Ligamentotaxis in Posterior Spinal Instrumentation of Thoracolumbar Retropulsed Fractures.

Aim: To compare the efficiency of distraction and ligamentotaxis in posterior spinal instrumentation of thoracolumbar retropulsed fractures according to the grade of spinal canal compression and fracture levels.

Material And Methods: This study retrospectively reviewed 56 patients diagnosed with thoracolumbar fractures and significant fracture fragments retropulsed into the spinal canal who only underwent posterior instrumentation with distraction and ligamentotaxis, and compared groups according to the grade of spinal canal compression and fracture levels. The pre-and postoperative clinical outcomes were evaluated using Oswestry Disability Index and visual analog scale scores, and neuroimaging studies showed percentage of the spinal canal compression and fractured vertebral unit height.

Local Tissue Electrical Resistances in Transpedicular Screw Application in the Thoracolumbar Region.

Aim: To determine local tissue electrical resistance differences generated during a screw pass from the pedicle to another tissue rather than determining all individual electrical tissue resistance values.

Material And Methods: We attempted to measure electrical resistance values of regional tissues in addition to fluoroscopic imaging during application of fixation via a transpedicular screw. We also attempted to detect local tissue electrical resistance alterations in case of malposition of the screw inside the pedicle.

Surgical management of Juxtafacet cysts in the lumbar spine.

Introduction: Juxtafacet cysts of the lumbar spine are extradural degenerative lesions associated with symptoms of lower back pain and radiculopathy. The aim of this study is to evaluate the efficacy of surgery and address controversial issues in the treatment of symptomatic juxta facet cysts in the Neurosurgical Department of our hospital and review of the literature.

Methods: Data from seven patients (age range 58-68 years, mean age 63 years) with low back and radicular leg pain due to a lumbar facet joint cyst were retrospectively analyzed.

Treatment of aneurysms arising from the proximal (A1) segment of the anterior cerebral artery.

The aim of our study was to report a series of 15 consecutive patients with aneurysms of the proximal segment (A1) of the anterior cerebral artery. In 15 patients with diagnosed A1 aneurysms, representing 2.1% of 720 aneurysm patients treated at a University Clinical Center between October 1999 and August 2012, clinical presentation, neuroradiological findings, surgical treatment methods and outcome were retrospectively analyzed.

Ruptured distal middle cerebral artery aneurysm: Case report.

Introduction: This report describes a rare case of a distal middle cerebral artery (dMCA) aneurysm.

Breast metastasis of anaplastic oligodendroglioma: a case report.

Extracranial metastasis of primary brain tumors is rarely observed. Of all brain malignancies, glioblastomas, medulloblastomas and astrocytomas metastasize most frequently. Metastasis of oligondendroglioma is rare.

Effect of systemic parameters following experimental subarachnoid hemorrhage and cerebral vasospasm in rabbits by injection of blood into the subarachnoidal space.

Biomarkers of connective tissue disease in patients with intracranial aneurysms.

Connective tissue defects may play a significant role in the development of intracranial aneurysms (IAs). Multiorgan connective tissue disorders may, therefore, indicate a risk of IA development. We investigated biomarkers of connective tissue disease in patients with IAs.

Objective: There is a growing interest in cystic lesions of the brain. Examining the cyst content of brain tumors may contribute in determining the malignancy of the given tumor accompanied by a cyst.

Methods: In this work, samples of cyst fluid from 18 patients with brain tumor were collected and studied biochemically regarding their protein, lactate contents and pH values; magnetic resonance spectroscopic images of these patients were also compared.

Total removal of cervicothoracic intramedullary 160-mm-long spinal cord ependymoma: a rare case report.

Ependymomas are neuroectodermal tumours arising from ependymal cells of the ventricular system, choroid plexus, filum terminale, or central canal of the spinal cord. We report on a 160-mm-long cervicothoracic intramedullary spinal cord ependymoma. The tumour was totally removed; no radiotherapy was used as an adjunctive therapy.
