We sought to identify predictors of death or discharge to home for patients with nontraumatic subdural hematoma (NT-SDH). ⋯ In this study, GCS score was the major predictor of outcome. Patients with NT-SDH who were male or with good GCS score were less likely to die and more likely to be discharged home. Unlike patients with intracerebral hemorrhage (ICH),lesion size did not predict outcome for patients with NT-SDH. Extent of involvement (on the right side) was a predictor of death.

Rapidly progressive fatal respiratory failure (Ondine's curse) in the lateral medullary syndrome.
A 70-year-old man presented with unilateral lateral medullary infarction, and then died of rapidly progressive respiratory failure within a day. The clinical manifestations were hiccups, hoarseness, dysarthria, nystagmus, left central facial paralysis, paralysis of the left soft palate, dysphagia, decreased superficial sensation over the right face and upper limb, and cerebellar ataxia in the left upper and lower limbs. The arterial blood gas analysis revealed mild hypoventilation. ⋯ Pathologically, there were fresh ischemic infarction localized to the left dorsolateral area of the upper medulla, caused by atherothrombotic occlusion of the left vertebral artery. These foci were in the areas including the medullary reticular formation, the solitary nucleus, the intramedullary fibers of the vagus nerve, and the nucleus ambiguus on the left side. We attributed the fatal acute progressive respiratory impairment in the present case to impairment of the automatic respiratory system (Ondine's curse) rather than the voluntary respiratory system.

International Subarachnoid Aneurysm Trial (ISAT) of neurosurgical clipping versus endovascular coiling in 2143 patients with ruptured intracranial aneurysms: a randomized trial.
Endovascular detachable coil treatment is being increasingly used as an alternative to craniotomy and clipping for some ruptured intracranial aneurysms, although the relative benefits of these two approaches have yet to be established. We undertook a randomized, multicenter trial to compare the safety and efficacy of endovascular coiling with standard neurosurgical clipping for such aneurysms judged to be suitable for both treatments. We enrolled 2143 patients with ruptured intracranial aneurysms and randomly assigned them to neurosurgical clipping (n = 1070) or endovascular treatment by detachable platinum coils (n = 1073). ⋯ The risk of rebleeding from the ruptured aneurysm after 1 year was two per 1276 and zero per 1081 patient-years for patients allocated endovascular and neurosurgical treatment, respectively. In patients with a ruptured intracranial aneurysm, for which endovascular coiling and neurosurgical clipping are therapeutic options, the outcome in terms of survival free of disability at 1 year is significantly better with endovascular coiling. The data available to date suggest that the long-term risks of further bleeding from the treated aneurysm are low with either therapy, although somewhat more frequent with endovascular coiling.

Cavernous carotid aneurysms rarely cause subarachnoid hemorrhage or major neurologic morbidity.
To determine whether aneurysms of the cavernous internal carotid artery (CCA) cause major neurologic morbidity or death. ⋯ CCA is a disorder with strong female gender bias that uncommonly causes major neurologic complications. These data suggest that CCA should not be included in analyses that determine the risk of severe neurologic morbidity, hemorrhage, or death due to intracranial aneurysms.

Diagnosis of perimesencephalic nonaneurysmal subarachnoid hemorrhage with computed tomography.
In 4% to 31% of patients with acute subarachnoid hemorrhage (SAH), no underlying cause is identified. Blood is restricted to the perimesencephalic cisterns in about two thirds of these patients. These patients are identified as having perimesencephalic nonaneurysmal subarachnoid hemorrhage (PNSAH), a syndrome based on the interpretation of computed tomography (CT) findings on admission, with an excellent prognosis, far better than other patients with SAH with or without an aneurysm. However, the diagnosis is subject to interrater variability, and differentiation between PNSAH and ruptured supratentorial aneurysm by means of CT has not been investigated. Therefore we investigated the validity of prediction of PNSAH with CT scan. ⋯ We conclude that PNSAH can be distinguished on CT in the majority of patients; however, the angiographical management in PNSAH should not differ from other SAHs.
