Background: Cerebral vasospasm is a major cause of morbidity and mortality in patients with subarachnoid hemorrhage. Vasospasm managed triple H vasodilators but sometimes, do not respond. Intra-arterial vasodilator infusion has been shown to improve outcome such patients. In this study, we try evaluate the efficacy intra-arterial nimodipine therapy 43 post-aneurysmal hemorrhage refractory cereb...

A 47-year-old man presented to our hospital with collapse secondary to a subarachnoid hemorrhage. A careful history taking revealed symptoms of anaphylaxis before his collapse. This case illustrates an unusual cause of subarachnoid hemorrhage.

BACKGROUND AND PURPOSE Our aim was to determine the patterns of error of radiology residents in the detection of intracranial hemorrhage on head CT examinations while on call. Follow-up studies were reviewed to determine if there was any adverse effect on patient outcome as a result of these preliminary interpretations. MATERIALS AND METHODS Radiology residents prospectively interpreted 22,59...

Free radicals and lipid peroxidation of membrane fatty acids are thought to play a role in the pathogenesis of arterial vasospasm and the physiopathologic patterns of neuronal damage after subarachnoid hemorrhage. We have evaluated the effects of treatment with either high-dose methylprednisolone every 8 hours or a single dose of U74006F on the temporal profile of ex vivo synthesis of four sele...

Aneurysmal subarachnoid hemorrhage (SAH) is a neurological emergency with high risk of neurological decline and death. Although the presentation of a thunderclap headache or the worst headache of a patient's life easily triggers the evaluation for SAH, subtle presentations are still missed. The gold standard for diagnostic evaluation of SAH remains noncontrast head computed tomography (CT) foll...

BACKGROUND Transient global amnesia is reported to be caused by cerebral venous congestion. Internal jugular venous flow reversal in particular with the Valsalva maneuver leads to cerebral venous congestion. In addition, Valsalva maneuver can also induce subarachnoid hemorrhage. Transient global amnesia and subarachnoid hemorrhage might have common a pathophysiology in cerebral venous congestio...

STUDY OBJECTIVE Clinical variables can reliably exclude a diagnosis of nontraumatic subarachnoid hemorrhage in patients with negative cranial computed tomography (CT) results. We externally validated 2 decision rules with 100% reported sensitivity for a diagnosis of subarachnoid hemorrhage, among patients undergoing lumbar puncture after a negative cranial CT result: (1) clinical rule: presence...

BACKGROUND AND PURPOSE To determine incidence and risks of subarachnoid hemorrhage in China. METHODS A prospective, population-based, 1:2 matched case-control study in Baotou, Inner Mongolia (≈2 million population) in 2009-2011. Multiple variable models used to determine relative risk and population-attributable risks for exposures. RESULTS For a total of 226 patients (mean age, 59 years; 6...

Although metabolic abnormalities have been linked with poor outcome after subarachnoid hemorrhage, there are limited data addressing the impact of glycemic control or benefits of glucose management after aneurysmal subarachnoid hemorrhage. A systematic literature search was conducted of English-language articles describing original research on glycemic control in patients with subarachnoid hemo...
