OBJECT In recent years, the importance of intraoperative navigation in neurosurgery has been increasing. Multiple studies have proven the advantages and safety of computer-assisted spinal neurosurgery. The use of intraoperative 3D radiographic imaging to acquire image information for navigational purposes has several advantages and should increase the(More)
The Glasgow Outcome Scale (GOS) score is widely used to assess outcome after a subarachnoid hemorrhage (SAH). Patients who have recovered fully or with a mild disability (GOS scores 4 and 5) frequently complain about difficulties in conducting their daily activities. The Short Form-36 (SF-36) Health Survey is a questionnaire that assesses outcomes in(More)
OBJECTIVE Endothelin-1 (ET-1) is postulated to play an important role in the development of cerebral vasospasm (CVS) following SAH. This study was conducted to investigate the time course of ET-release in three different sources: CSF, plasma and microdialysate. METHODS In a prospective study ET-1-concentrations were measured in plasma, cisternal CSF and(More)
The iatrogenic malnutrition of neurosurgical patients in intensive care units (ICU) is an underestimated problem. It may cause a decrease in plasma albumin and oncotic pressure, leading to an increase in the amount of water entering the brain and increased intracranial pressure (ICP). This study was conducted to test the hypothesis that combined(More)
After subarachnoid hemorrhage (SAH) the detection of hemodynamically significant vasospasm is frequently difficult, especially in comatose patients. Most clinicians use transcranial Doppler sonography (TCD) to detect increasing mean blood flow velocities in the basal arteries as markers of cerebral vasospasm, without accounting for the effects of sedation(More)
After subarachnoid hemorrhage (SAH) cerebral metabolism is significantly impaired. Hyperglycolysis describes the reduction of oxidative metabolism followed by a relative increase of anaerobic glycolysis to maintain energy supply. This phenomenon is known in head injury but has not as yet been shown after SAH. This study was conducted to test the hypothesis(More)
BACKGROUND Calcium (Ca2+) is a cofactor of multiple cellular processes. The mechanisms that lead to elevated cytosolic Ca2+ concentration are unclear. OBJECTIVE To illuminate how bloody cerebrospinal fluid (bCSF) from patients with intraventricular hemorrhage causes cell death of cultured human astrocytes. METHODS Cultured astrocytes were incubated with(More)
The original ICH (oICH) score was tested in different populations and showed good accuracy in the prediction of outcome and 30-day mortality after spontaneous ICH. The oICH was developed to stratify patients with all types of spontaneous intracerebral hemorrhage (SICH). Several modifications of the oICH score exist in the literature.In the current study, we(More)
BACKGROUND The number of elderly patients being admitted with aneurysmal subarachnoid haemorrhage (SAH) has been increasing. Treatment of the aneurysm may be offset by the higher rate of surgical or endovascular complications. AIM To study the clinical condition at onset, complications during clinical course, treatment and outcome in a consecutive series(More)
We present a patient with a solitary brainstem abscess caused by Haemophilus influenza type b (Hib) and Peptostreptococcus species. This is the first report of a Hib brainstem abscess in the English literature. Hib has been mainly associated with respiratory or nasal infections, and a few cases of intracerebral abscesses, but no brainstem abscesses have(More)
