    BACKGROUND: Relatively high rates of complications occur after operation for unruptured intracranial aneurysms. Published data on endovascular treatment suggest lower rates of complications. We measured the impact of treatment of unruptured aneurysms by clipping or coiling on functional health, quality of life, and the level of anxiety and depression.

    METHODS: In three centres, we prospectively collected data on patients with an unruptured aneurysm who were treated by clipping or ...

    INTRODUCTION: We sought to establish whether CT angiography (CTA) can be applied to the planning and performance of clipping or coiling in ruptured intracranial aneurysms without recourse to intraarterial digital subtraction angiography (IA-DSA).

    METHODS: Over the period April 2003 to January 2006 in all patients presenting with a subarachnoid haemorrhage CTA was performed primarily. If CTA demonstrated an aneurysm, coiling or clipping was undertaken. IA-DSA was limited to patients with ...

    OBJECTIVE: To investigate prospectively the proportion of patients actually operated on early in units that aim at surgery in the acute phase of aneurysmal subarachnoid haemorrhage (SAH) and what is the main current determinant of poor outcome.

    METHODS: A prospective analysis of all SAH patients admitted during a one year period at three neurosurgical units that aim at early surgery. The following clinical details were recorded: age, sex, date of SAH, date of admission to the ...

    OBJECTIVE: The aim of this study was to investigate prospectively in an unselected series of patients with an aneurysmal subarachnoid haemorrhage what at present the complications are, what the outcome is, how many of these patients have "modern treatment"-that is, early obliteration of the aneurysm and treatment with calcium antagonists-what factors cause a delay in surgical or endovascular treatment, and what the estimated effect on outcome will be of improved treatment.

    METHODS: A ...

    OBJECTIVES: To focus attention of the clinician on the anatomy and (patho)physiology of the vertebral venous system, so as to offer a tool to better understand and anticipate (potential) complications that are related to the application of percutaneous vertebroplasty and kyphoplasty.

    BACKGROUND: Percutaneous vertebroplasty and kyphoplasty are newly developed, minimally invasive techniques for the relief of pain and for the strengthening of bone in vertebral body lesions. With the ...

    Reviewing the literature on the vascular anatomy of the spinal epidural space, it appeared that the knowledge of the internal vertebral venous plexus is limited. Injection studies of the entire internal vertebral venous plexus after application of modern techniques, to the best of our knowledge, have never been performed. Based on the clinical importance of these structures, it was decided to study the human vertebral venous system after Araldite CY 221 injection, in order to update the ...

    OBJECT: In this paper the authors systematically evaluate the results of different surgical procedures for chronic subdural hematoma (CSDH).

    METHODS: The MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and other databases were scrutinized according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) statement, after which only randomized controlled trials (RCTs) and quasi-RCTs were included. At least 2 different neurosurgical procedures in ...

    PURPOSE: To calculate the sensitivity and specificity of computed tomographic (CT) angiography in the diagnosis of cerebral aneurysms in patients with acute subarachnoid hemorrhage (SAH) at presentation.

    MATERIALS AND METHODS: A systematic search for relevant studies was performed of the PubMed/MEDLINE and EMBASE databases. Two reviewers independently assessed the methodologic quality of each study by using the Quality Assessment of Diagnostic Accuracy Studies tool. The inclusion ...

    BACKGROUND AND PURPOSE: The purpose of this study was to investigate the current direct costs of modern management of patients with aneurysmal subarachnoid hemorrhage in the first year after diagnosis.

    METHODS: During a 1-year period, we studied all admitted patients with subarachnoid hemorrhage from a population of 2 million people. We calculated the direct costs of treatment, which included the costs of medical and nursing care and the related travel expenses of patients. We calculated ...

    Objective. To identify factors that favour spontaneous recovery in patients who suffered a spontaneous spinal epidural hematoma (SSEH).Methods. The literature was reviewed reguarding non-operative cases of SSEH (SSEHcons). Sixty-two cases from the literature and 2 of our own cases were collected, focusing on sex, age, medical history, position of the hematoma, segmental distribution and length of the hematoma, diagnostic imaging, neurological condition and outcome. Those data were ...

    OBJECT: A repeat digital subtraction angiography (DSA) study of the cranial vasculature is routinely performed in patients with diffuse nonperimesencephalic subarachnoid hemorrhage (SAH) after negative baseline CT angiography (CTA) and DSA studies. However, DSA carries a low but substantial risk of neurological complications. Therefore, the authors evaluated the added value of repeat DSA in patients with initial angiographically negative diffuse nonperimesencephalic SAH.

    METHODS: A ...

    OBJECTIVE: We clarify the factors affecting postoperative outcomes in patients who have suffered spontaneous spinal epidural hematomas.

    METHODS: We review 330 cases of spontaneous spinal epidural hematomas from the international literature and three unpublished cases of our own. Attention was focused on sex, age, medical history, mortality, size and position of the hematoma, vertebral level of the hematoma, preoperative neurological condition, operative interval, and postoperative ...

    OBJECTIVE: Anterior thoracic spinal cord herniation is a rare cause of progressive myelopathy. Much has been speculated about the best operative treatment. However, no evidence in favor of any of the promoted techniques is available to date. Therefore, we decided to analyze treatment procedures and treatment outcomes of anterior thoracic spinal cord herniation to identify those factors that determine postoperative outcome.

    METHODS: An individual patient data meta-analysis was conducted, ...
