BACKGROUND AND PURPOSE The diagnosis of subacute subarachnoid hemorrhage is important because rebleeding may occur with subsequent life-threatening hemorrhage. Our aim was to determine the sensitivity of the 3D double inversion recovery sequence compared with CT, 2D and 3D FLAIR, 2D T2*, and 3D SWI sequences for the detection of subacute SAH. MATERIALS AND METHODS This prospective study inclu...

Acute paraplegia is a rare presentation for a spinal cord ependymoma. Subarachnoid hemorrhage (SAH) due to spinal ependymoma is also very rare. We report a 32-year-old woman who presented with acute paraplegia and typical clinical signs of SAH with normal cerebral angiography, and further diagnostic work-up revealed an spinal cord ependymoma as the source of the hemorrhage. There is evidence th...

The subarachnoid hemorrhage (SAH) is definitely the best descriptive model of the interaction between cardiovascular system and cerebral damage. The underlying mechanism of cardiovascular alterations after SAH is linked to the adrenergic discharge related to aneurysm rupture. Cardiac and pulmonary complications are common after severe brain injury, especially the aneurismal subarachnoid hemorrh...

BACKGROUND AND PURPOSE SWI is an MR imaging technique that is very sensitive to hemorrhage. Our goal was to compare SWI and CT to determine if SWI can show traumatic SAH in different parts of the subarachnoid space. MATERIALS AND METHODS Twenty acute TBI patients identified by CT with SAH underwent MR imaging scans. Two neuroradiologists analyzed the CT and SWI data to decide whether there we...

BACKGROUND AND PURPOSE We analyzed the temporal and spatial pattern of water diffusion changes during acute subarachnoid hemorrhage (SAH) in rat brain to identify factors contributing to the acute pathophysiology of SAH. METHODS Subarachnoid hemorrhage was remotely induced via perforation of the circle of Willis with an endovascular suture during MR imaging. A fast echo-planar imaging techniq...

An electronic literature search through August 2010 was performed to obtain articles describing fever incidence, impact, and treatment in patients with subarachnoid hemorrhage. A total of 24 original research studies evaluating fever in SAH were identified, with studies evaluating fever and outcome, temperature control strategies, and shivering. Fever during acute hospitalization for subarachno...

was referred to the neurology department for comatose state with brainstem dysfunction. Non-contrast brain CT showed diffuse cerebral edema with subarachnoid hemorrhage (SAH)-like appearance (Fig. 1A). A lumbar puncture was not carried out because of the brain edema which was revealed in CT examination. T2*-weighted gradient-echo MRi revealed enlarged subarachnoid vessels that were not consiste...

Devices to produce experimental subarachnoid hemorrhage (SAH) can be implanted in animals. After SAH is produced by the puncture of a middle cerebral artery (MCA) in awake cats, neurologic deficits develop that are not as severe as those caused by MCA occlusion. Biphasic increases of epidural pressure occur and are related to the extent and distribution of the hemorrhage. Ischemic changes are m...

BACKGROUND AND PURPOSE The aim of our study was to compare outcome and its determinants in familial subarachnoid hemorrhage and in sporadic subarachnoid hemorrhage in a large and well-documented patient population. METHODS Patients with aneurysmal subarachnoid hemorrhage (SAH) treated at the Department of Neurosurgery, Kuopio University Hospital, from 1977 to 1995 were included. Patients with...

UNLABELLED After subarachnoid hemorrhage (SAH), large cerebral arteries are prone to vasospasm. Using a rat model of SAH, we examined whether cortical microvessels demonstrate vasomotor changes that may make them prone to spasm and whether endothelial dysfunction may account for any observed changes. Two days after percutaneous catheterization into the cisterna magna, 0.3 mL of autologous blood...
