Case ReportsLimitations of jugular bulb oxyhemoglobin saturation without intracranial pressure monitoring in subarachnoid hemorrhage.
We report a case of subarachnoid hemorrhage in which, even after having obtained a normal jugular bulb oxyhemoglobin saturation, cerebrovenous desaturation developed, and brain death occurred. The limitations of jugular bulb oxyhemoglobin saturation without intracranial pressure monitoring are discussed. We conclude that if increased intracranial pressure is suspected, use of jugular bulb oxyhemoglobin saturation monitoring alone would appear to be substantially limited.

Case ReportsPleomorphic xanthoastrocytoma presenting with massive intracranial hemorrhage.
A 46-year-old woman presented with massive left temporal lobe intraparenchymal and diffuse subarachnoid hemorrhage on CT. Lack of enhancement excluded intermediate and high-grade primary tumor or metastasis as likely causes. At surgery, a fibrovascular left temporal lobe mass adherent to the dura proved to be a pleomorphic xanthoastrocytoma. The unusual hemorrhagic presentation of this typically benign entity is thought to be related to the meningeal involvement, which itself is characteristic of this neoplasm.

Multicenter Study[Anesthesia and intensive care of subarachnoid hemorrhage. A survey on practice in 32 centres].
To assess the current practices in anaesthesia and intensive care in patients experiencing subarachnoid haemorrhage (SAH). ⋯ Twenty-nine French and three non French centers answered the questionnaire. In 14 centers, more than 60 SAH had been treated in the previous year. Angiography was performed under sedation with a benzodiazepine associated with an opioid (54%). Criteria for choosing an endovascular approach were the site of the aneurysm (81%), its neck size (42%) and the underlying disease (42%). Anaesthesia was induced with either propofol (60%) or thiopentone (40%) associated with an opioid and a muscle relaxant. It was maintained with either isoflurane (59%) or propofol (41%). Nitrous oxide was often associated (62%). During anaesthesia, nimodipine (84%), mannitol (69%), anticonvulsants (47%), dopamine (31%) and lidocaine (9%) were also administered. Postoperatively, nimodipine was administered for prophylaxis of vasospasm (97%) and transcranial Doppler was employed to diagnose vasospasm (50%). Other techniques of care included hypervolaemia (89%), controlled arterial hypertension (36%) and haemodilution (36%).

Our purpose was to review the incidence of negative cerebral panangiography in acute nontraumatic subarachnoid haemorrhage (SAH); to document the amount and distribution of subarachnoid blood on CT and determine its relationship to findings on repeat angiography; and to study the outcome of these patients from the time of presentation to hospital discharge. From 1983 to 1992, 295 patients underwent cerebral angiography for acute SAH at our institution. The CT, angiographic and MRI findings and clinical course of patients with initially negative angiograms were reviewed retrospectively. ⋯ There were two deaths related to massive rebleeding. Patients with perimesencephalic SAH (35%) fared particularly well; none developed complications during their hospital stay and repeat angiograms never revealed an underlying aneurysm. In such cases, further angiographic investigations do not seem warranted.

Does nimodipine influence sex difference in outcome after aneurysmal subarachnoid haemorrhage?
Before nimodipine was introduced as a standard treatment in patients with aneurysmal subarachnoid haemorrhage (SAH) females had a significantly poorer outcome which might be due to a higher frequency of delayed cerebral ischaemia (DCI). We evaluated the overall outcome with regard to gender in 188 consecutive patients with a verified ruptured intracranial aneurysm treated with nimodipine. ⋯ However, contrary to previous studies, we found no difference in overall outcome after three months between the sexes in this clinical material. Our observation can be explained by a positive effect of nimodipine on DCI.
