A method for induction of subarachnoid hemorrhage (SAH) in a rat model is described. Resolution of the hemorrhage was documented photographically and microscopically at intervals from 1 hr to 8 days. Photographs indicated that most of the hemorrhage was resorbed within 3 days, an observation confirmed microscopically by the amount of red blood cells in the subarachnoid space. Significant cerebr...

Subarachnoid hemorrhage (SAH) is a common and often devastating occurrence; each year approximately 30 000 Americans have nontraumatic SAH. Despite considerable advances in diagnostic techniques, surgical, and anesthetic techniques and perioperative management, the outcome for patients with SAH remains poor, with overall mortality rates of 25% and significant morbidity among approximately 50% o...

Subarachnoid hemorrhage (SAH) is a common and often devastating occurrence; each year approximately 30 000 Americans have nontraumatic SAH.1 Despite considerable advances in diagnostic techniques, surgical, and anesthetic techniques and perioperative management, the outcome for patients with SAH remains poor, with overall mortality rates of 25% and significant morbidity among approximately 50% ...

Abstract Background Stroke is a neurological emergency that tends to be the first cause of death in many countries. Atmospheric variables are strongly associated with stroke, which subarachnoid hemorrhage (SAH) has been studies meteorological risk factors such as air pollution, pressure, weather changes, and ambient temperature. These characteristics may influence brain circulation SAH, being d...

Cerebral vasospasm and delayed cerebral ischemia are common complications associated with subarachnoid hemorrhage (SAH) outcomes. Various modalities can be used to evaluate detect after SAH. Transcranial Doppler (TCD) ultrasonography as an appropriate bedside dynamic monitoring tool screen for the presence progression of in patients This article briefly reviewed severity SAH pathophysiology vas...

Very rarely, spinal subarachnoid hemorrhage (SSAH) can occur without any direct spinal injury in patients with traumatic intracranial SAH. A-59-year-old male with traumatic intracranial subarachnoid hemorrhage (SAH) presented with pain and numbness in his buttock and thigh two days after trauma. Pain and numbness rapidly worsened and perianal numbness and voiding difficulty began on the next da...

Delayed cerebral ischemia (DCI) is a major determinant of patient outcome following aneurysmal subarachnoid hemorrhage. Although the exact mechanisms leading to DCI are not fully known, inflammation, cerebral vasospasm, and microthrombi may all function together to mediate the onset of DCI. Indeed, inflammation is tightly linked with activation of coagulation and microthrombi formation. Thrombo...

We describe a case of dural arteriovenous fistula (DAVF) presenting with subarachnoid hemorrhage (SAH). The diagnosis of DAVF was based on spinal angiography. A review of the literature revealed that five of 13 previously reported DAVFs of the cervical spine were accompanied by SAH. SAH has not been observed in DAVFs involving other segments of the spinal canal.

OBJECTIVES Aim of this study was to compare the utility of susceptibility weighted imaging (SWI) with the established diagnostic techniques CT and fluid attenuated inversion recovery (FLAIR) in their detecting capacity of subarachnoid hemorrhage (SAH), and further to compare the combined SWI/FLAIR MRI data with CT to evaluate whether MRI is more accurate than CT. METHODS Twenty-five patients ...
