BACKGROUND Intraoperative MRI is increasingly used in neurosurgery, although there is little evidence for its use. We aimed to assess efficacy of intraoperative MRI guidance on extent of resection in patients with glioma. METHODS In our prospective, randomised, parallel-group trial, we enrolled adults (≥18 years) with contrast enhancing gliomas amenable(More)
OBJECTIVES To review the angiographic and clinical outcome of patients with unruptured intracranial aneurysm(s) (UIA) with regard to complications and successful obliteration by surgical clipping or endovascular coiling. METHODS Data were derived from a prospective database of intracranial aneurysms from June 1999 to May 2005. All patients were(More)
Decompressive craniectomy (DC) due to intractably elevated intracranial pressure mandates later cranioplasty (CP). However, the optimal timing of CP remains controversial. We therefore analyzed our prospectively conducted database concerning the timing of CP and associated post-operative complications. From October 1999 to August 2011, 280 cranioplasty(More)
Chronic subdural haematoma (cSDH) is a common disease in neurosurgical practise, especially in elderly patients. This is of growing importance as the number of elderly people in the population is increasing steadily. There are scarce data focussing especially on elderly patients with cSDH. This study intended to evaluate the outcome and peri-operative risks(More)
The aim of this prospective study was to analyse small band-like cortical infarcts after subarachnoid haemorrhage (SAH) using magnetic resonance imaging (MRI) with reference to additional digital subtraction angiography (DSA). In a 5-year period between January 2002 and January 2007 10 out of 188 patients with aneurysmal SAH were evaluated (one patient Hunt(More)
OBJECT The objective of this study was to analyze whether age influences the outcome of patients with glioblastoma and whether elderly patients with glioblastoma can tolerate the same aggressive treatment as younger patients. METHODS Data from 361 consecutive patients with newly diagnosed cerebral glioblastoma (2000-2006) who underwent regular follow-up(More)
Aseptic bone flap resorption (BFR) is a known long-term complication after cranioplasty (CP). We analyzed our institutional data in order to identify risk factors for BFR. From October 1999 to April 2012, 254 patients underwent CP after decompressive craniectomy (DC) at our institution, and had a long-term follow-up period of >1 year after CP (range 12-146(More)
Endothelin-1 (ET-1) may be involved in the upregulation of cerebroarterial resistance under pathologic conditions, most notably in the development of vasospasm after subarachnoid hemorrhage. Therefore, blocking the contractile action of ET-1 by receptor antagonists may prove to be a new and worthwhile approach. However, decreasing synthesis and release of(More)
BACKGROUND The purpose of this study was to examine a possible association between standard meteorological variables and their changes and the occurrence and clinical features of SAH. METHODS Univariate association between the clinical/radiographic variables of patients with SAH and standard meteorological variables was evaluated. Next, a multivariate(More)
OBJECT In this report, the authors describe their experience in the surgical management of spinal meningiomas at two neurosurgical centers. The results of a literature review are also presented. METHODS Eighty consecutive patients (22 men and 58 women) with spinal meningiomas who had undergone an operation at two specific neurosurgical centers were(More)
