Intra-Arterial Delivery of Idarubicin in Two Patients with Glioblastoma.

There is no effective treatment for recurrent glioblastoma (GB) when temozolomide-based radiochemotherapy fails. In theory, intra-arterial (IA) delivery of cytotoxic agents could achieve higher drug concentrations in tumors compared to intravenous injection. Moreover, choosing a highly lipid-soluble drug could make the most of the first-pass effect.

An unusual, duplicate origin of the anterior choroidal artery with aneurysm: a case report.

Background And Importance: Aneurysms of the anterior choroidal artery (AChoA) are rare and often difficult to treat. Variations may be present and must be identified prior to treatment. We report a unique case of a ruptured aneurysm located at the origin of a duplicate branch of the AChoA.

Should we fear cement leakage during kyphoplasty in percutaneous traumatic spine surgery? A single experience with 76 consecutive cases.

Objective: Although kyphoplasty is widely used to repair osteoporotic and pathologic vertebral fractures, balloon kyphoplasty and vertebral body stenting are new treatment options in cases of traumatic spinal injury. To our knowledge, there are no literature data on the incidence of cement leakage whereas these two percutaneous techniques are commonly used to repair non-pathologic fractures. The aim of this study was to evaluate and compare the clinical characteristics and the incidence of cement leakage associated with balloon kyphoplasty and vertebral body stenting in the percutaneous treatment of traumatic spinal injury.

A relapsing macrodactyly.

Lipofibromatous hamartoma is an uncommon benign tumor, usually unknown or misdiagnosed. We report the case of a 61-year-old patient presenting an acquired painful macrodactyly of the left thumb with paresthesia in the median nerve territory. Clinical examination reveals a tumefaction of the volar side of the wrist.

[Type II proatlantal artery with unusual origin of the occipital artery feeding of a type IV dural arteriovenous fistula: case report].

We report the case of a 49 year-old woman, who presented with an intracranial haemorrhage. During cerebral angiography investigations, we observed an unusual vertebral artery that originated from the external carotid artery and an uncommon origin of the occipital artery from the vertebral artery feeding a dural arteriovenous fistula grade IV. This rare vertebral artery origin is probably the remnant of a type II proatlantal artery.

Percutaneous vertebroplasty of the C2 body and dens using the anterior oblique ascending transdiscal approach.

This first description of percutaneous vertebroplasty (PVP) of the second cervical vertebra (C2) using an ascending oblique transdiscal approach is a case report of a 63-year-old woman who complained of neck pain that was resistant to painkillers and the result of an osteolytic metastatic lesion of C2. PVP was performed using an ascending oblique transdiscal approach, a percutaneous technique that had never been described before. It has since been used in more than 15 patients, resulting in pain relief and stabilization of C2 with good distribution of cement across the vertebral body and dens.

Cerebral Blood and CSF Flow Patterns in Patients Diagnosed for Cerebral Venous Thrombosis - An Observational Study.

Background And Purpose: Recent studies of the organization of the cerebral venous system in healthy subjects using phase contrast magnetic resonance imaging (PC-MRI) show its structural complexity and inter-individual variations. Our objective was to study the venous blood and CSF flows in cerebral venous thrombosis (CVT).

Materials And Methods: PC-MRI sequences were added to brain MRI conventional protocol in 19 patients suspected of CVT, among whom 6 patients had CVT diagnosis confirmed by MR venography.

Minimally invasive management of thoraco-lumbar fractures: combined percutaneous fixation and balloon kyphoplasty.

Study Design: Retrospective review of prospectively collected data.

Background: There is no consensus regarding the ideal treatment of thoraco-lumbar spine fractures without neurological compromise. Many surgical techniques have been described but none has proved its definite superiority.

Perfusion MRI as a neurosurgical tool for improved targeting in stereotactic tumor biopsies.

Objective: Stereotactic biopsies are subject to sampling errors (essentially due to target selection). The presence of contrast enhancement is not a reliable marker of malignancy. The goal of the present study was to determine whether perfusion-weighted imaging can improve target selection in stereotactic biopsies.

Cognitive impairment and dementia after intracerebral hemorrhage: a cross-sectional study of a hospital-based series.

Background: Frequencies of cognitive impairment and dementia have not been assessed in spontaneous intracerebral hemorrhage (ICH). The objective of this study was to determine the frequencies and patterns of cognitive impairment and dementia in a cross-sectional study of consecutive patients hospitalized in a single university medical center.

Methods: Of 183 consecutive patients hospitalized between 2002 and 2006, 80 survivors were contacted and 78 were included (mean time since stroke 40 months).

Functional consequences of a section of the anterior part of the body of the corpus callosum: evidence from an interhemispheric transcallosal approach.

The aim of this study was to determine the neuropsychological consequences of a middle interhemispheric approach for the removal of tumors of the third or lateral ventricles. A retrospective analysis of eight callosotomized patients for ventricular tumors (three males/five females; mean age: 48.7 ± 11.

Correlation between tap test and CSF aqueductal stroke volume in idiopathic normal pressure hydrocephalus.

Introduction: The diagnosis and management of idiopathic normal pressure hydrocephalus (INPH) remains unclear despite the development of guidelines. In addition, the role of cerebrospinal fluid (CSF) aqueductal stroke volume (ASV) remains unspecified.

Objectives: The aim of this study was to compare the results of the tap test (TT) and ASV in patients with possible INPH.

Presence of intracranial artery calcification is associated with mortality and vascular events in patients with ischemic stroke after hospital discharge: a cohort study.

Background And Purpose: Although intracranial artery calcification (IAC) has been reported to be a risk factor for ischemic stroke, the prognostic implications of IAC in stroke outcome are unknown. The purpose of this study was to determine the association between IAC and risk of vascular events and death in patients with stroke after hospital discharge.

Methods: All patients with ischemic stroke over a 1-year period were included (n=302).

A phase-contrast MRI study of acute and chronic hydrodynamic alterations after hydrocephalus induced by subarachnoid hemorrhage.

Objective: To determine acute intracranial hydrodynamic changes after subarachnoid hemorrhage (SAH) via phase-contrast MRI (PC-MRI) analysis of the CSF stroke volume in the aqueduct (SVaq) and the foramen magnum (SVfm).

Methods: A prospective PC-MRI study was performed on 34 SAH patients in the acute and late phase. Data on CSF flow and hemorrhage site were analyzed according to acute or chronic hydrocephalus (HC).

Cerebrospinal fluid and blood flow in mild cognitive impairment and Alzheimer's disease: a differential diagnosis from idiopathic normal pressure hydrocephalus.

Background: Phase-contrast magnetic resonance imaging (PC-MRI) enables quantification of cerebrospinal fluid (CSF) flow and total cerebral blood (tCBF) flow and may be of value for the etiological diagnosis of neurodegenerative diseases. This investigation aimed to study CSF flow and intracerebral vascular flow in patients with Alzheimer's disease (AD) and patients with amnesic mild cognitive impairment (a-MCI) and to compare the results with patients with idiopathic normal pressure hydrocephalus (NPH) and with healthy elderly volunteers (HEV).

Methods: Ten a-MCI and 9 mild AD patients were identified in a comprehensive neurological and neuropsychological assessment.
