BACKGROUND AND PURPOSE Aneurysmal subarachnoid hemorrhage is a serious disease despite recent improvements in medical and surgical treatment. Hence, identification of modifiable risk factors for subarachnoid hemorrhage is important. METHODS We compared the smoking and drinking habits of 278 consecutive patients with aneurysmal subarachnoid hemorrhage, aged 15-60 years (145 men and 133 women) ...

We present the case of a 7-month-old female infant who was found crying and limp. She was transported to a hospital where a possible subarachnoid hemorrhage was diagnosed radiologically. Before further studies could be pursued, her condition worsened and she died. The autopsy demonstrated diffuse subarachnoid hemorrhage of the brain and along the spinal cord. The brain, spinal cord, and eyes we...

BACKGROUND Cerebral vasospasm is commonly seen in subarachnoid hemorrhage. However the vasospasm in spontaneous intracerebral hemorrhage without subarachnoid extension has not been described. REPORT We report a patient who developed intracerebral hemorrhage associated with cerebral vasospasm demonstrated by conventional angiography. The vasospasm involved the superior and inferior divisions o...

hemorrhage had been found in the posterior circulation such as vertebral artery in majority cases, but reported cases in the anterior circulation was rare. Those located in the anterior circulation usually manifest as ischemic stroke resulting from arterial stenosis or occlusion. However, spontaneous subarachnoid hemorrhage in these cases is rare. So, we report a case of dissecting aneurysm of ...

BACKGROUND AND PURPOSE The role of the cerebral microcirculation in delayed ischemia after subarachnoid hemorrhage remains obscure. To test the hypothesis that cerebral arterioles have a reduced capacity to dilate after subarachnoid hemorrhage, we studied the microvascular responses to papaverine (PPV) in patients undergoing aneurysm surgery. Method- In 14 patients undergoing aneurysm surgery, ...

BACKGROUND AND PURPOSE Clear elucidation of the exact pathophysiological mechanisms of motor weakness in patients with subarachnoid hemorrhage has not yet been achieved. We attempted to investigate injury to the corticospinal tract in patients with subarachnoid hemorrhage using diffusion tensor imaging. METHODS Twenty-two patients with subarachnoid hemorrhage and 24 control subjects were recr...

Terson syndrome refers to oculocerebral syndrome of retinal and vitreous hemorrhage associated with spontaneous subarachnoid hemorrhage or all forms of intracranial bleeding. Recent observations have indicated that patients with spontaneous subarachnoid hemorrhage have an 18% to 20% concurrent incidence of retinal and vitreous hemorrhages with about 4% incidence of vitreous hemorrhage alone. Cl...

PURPOSE To determine the usefulness of CT angiography in the setting of suspected acute subarachnoid hemorrhage or intracranial aneurysm. METHODS We prospectively studied 68 patients suspected of having subarachnoid hemorrhage or an intracranial aneurysm with noncontrast CT of the head followed immediately by contrast-enhanced helical CT of the circle of Willis with three-dimensional reconstr...

A case-control analysis is used to examine the relation of cigarette smoking, hypertension and the risk of subarachnoid hemorrhage in men and women aged 35-64 years. 45 men and 70 women with subarachnoid hemorrhage were identified as part of a large community based study of stroke, and the controls, 1017 men and 569 women, came from a survey of cardiovascular risk factors conducted in the same ...

Although genetic epidemiological studies have implicated several genetic variants as risk factors for hemorrhagic stroke, the genetic determinants of this condition remain largely unknown. We examined an association of genetic variants with intracerebral or subarachnoid hemorrhage among Japanese individuals. The study population comprised 4,304 unrelated Japanese individuals, including 377 subj...
