Subarachnoid hemorrhage (SAH) is the subtype of stroke with one of the highest mortality rates and the least well-understood pathophysiologies. One of the very early events which may occur after SAH is a significant decrease of cerebral perfusion pressure (CPP) caused by the excessive increase of intracranial pressure during the initial bleeding. A severely decreased CPP results in global cereb...

A man visited the emergency room with a headache. Brain computed tomography showed aneurysmal subarachnoid hemorrhage (SAH) and multiple aneurysms. After aneurysm clipping surgery, the patient was discharged. After 5 days, he was admitted to the hospital with skin ulceration and was diagnosed with Behcet syndrome. An angiogram taken 7 weeks after aneurysmal SAH showed intracranial vasospasm. Be...

OBJECTIVE To assess trends in mortality from 1999 to 2008 resulting from non-traumatic subarachnoid hemorrhage (SAH) in the Colombian population. METHOD This population-based study analyzed all deaths by assuming a Poisson model. RESULTS Subarachnoid hemorrhage-related deaths showed a statistically significant increase of 1.6% per year (p<0.001). The age-standardized analysis demonstrated a...

motor vehicle and falling down are responsible for the most number of traumatic injuries. this study aimed to compare the characteristics of traumatic brain injury among accident and falling down cases. in this analytical cross- sectional study, data were collected from the records of cadavers who died due to accident or falling down and referred to kahrizak dissection hall, tehran forensic med...

We report a case of spinal subarachnoid hemorrhage (SAH) caused by rupture of a mycotic anerurysm. A 59-year-old woman was admitted to our hospital with a sudden onset of headache and tetraparesis. Computed tomography (CT) scan of the brain revealed SAH, and magnetic resonance imaging (MRI) of the cervical spine showed an acute intradural hematoma. On angiogram, a saccular aneurysm was found on...

Aneurysmal subarachnoid hemorrhage (SAH) is an acute neurologic emergency. We report the case of a 48-year-old male with massive SAH caused by ruptured aneurysm vertebrobasilar transition. During urgent craniotomy, due to re-rupture, adenosine was given for flow arrest but no sinus pause observed. Esmolol administered and strategies cerebral protection were implemented. The surgeon able clip pa...

AIM We set forth to identify predictors of symptomatic vasospasm in patients with subarachnoid hemorrhage (SAH). MATERIAL AND METHODS We used multivariate logistic regression analysis of the prospective, hospital based, single center register of the Department of Neurosurgery, University of Debrecen, Hungary. Evaluated patients' characteristics were: sex, age, Hunt-Hess grade on admission, lo...

INTRODUCTION A neurysmal subarachnoid hemorrhage (SAH) affects approximately 30,000 Americans each year. The incidence approximates 6 to 16 per 100,000 persons per year, with some geographic variation throughout the world. There has been a modest decline in incidence over time, in contrast to more marked decreases in incidence of other types of stroke (such as ischemic stroke and intracerebral ...

Objective: This study investigated the expression of TRPC1 and TRPC4 in the basilar artery in a rat subarachnoid hemorrhage (SAH) model, and clarified the potential role of TRPC1 and TRPC4 in cerebral vasospasm. Methods: Seventy-two rats were randomized into six groups: control, day 1, day 3, day 5, day 7, and day 14 groups. The day 1, day 3, day 5, day 7, and day 14 groups were the SAH groups....

Background: One of the clinical manifestations and complications traumatic brain injury patients is intracranial hemorrhages, divided into primary secondary hemorrhages. Objectives: The present study was conducted to determine prevalence subarachnoid hemorrhage (SAH) in (TBI) patients. Methods: cross-sectional on all TBI with SAH for one year. Data collection tools include a demographic profile...
