Glycine and GABA, the dominant inhibitory neurotransmitters in the CNS, assume a depolarizing role in early development, leading to increased cytoplasmic Ca2+ levels and action potentials. The effect is thought to be of some significance for maturation. The depolarization is caused by Cl- efflux, and chloride transporters contribute to the phenomenon by(More)
OBJECT Catheter-related infection of CSF is a potentially life-threatening complication of external ventricular drainage (EVD). When using EVD catheters, contact between the ventricular system and skin surface occurs and CSF infection is possible. The aim of this analysis was to compare the efficacy of silver-bearing EVD catheters for reducing the incidence(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)
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)
Data on arteriovenous malformations (AVMs) of the brain with AVM-associated aneurysms (AAA) are scarce. This study addresses the incidence, rate of hemorrhage, treatment strategies and stability during follow-up in a neurovascular center. We retrospectively reviewed patients harboring an AVM with at least one AAA treated at our neurovascular center between(More)
OBJECTIVE To analyze the incidence and impact of an intracerebral hematoma (ICH) on treatment and outcome in patients with aneurysmal subarachnoid hemorrhage. METHODS Data of 585 consecutive patients with subarachnoid hemorrhage from June 1999 to December 2005 were prospectively entered in a database. ICH was diagnosed and size was measured by computed(More)
OBJECT The aim of this study was to analyze decompressive craniectomy (DC) in the setting of subarachnoid hemorrhage (SAH) with bleeding, infarction, or brain swelling as the underlying pathology in a large cohort of consecutive patients. METHODS Decompressive craniectomy was performed in 79 of 939 patients with SAH. Patients were stratified according to(More)
BACKGROUND Compression of the third nerve resulting in oculomotor nerve palsy (ONP) is a common initial symptom and in some cases the only neurological deficit in patients with posterior communicating artery (PcomA) aneurysms. OBJECTIVE To analyze the resolution of ONP after surgical or endovascular treatment in comparison with its spontaneous course. (More)
