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...

BACKGROUND Cerebral vasospasm can be defined as delayed-onset narrowing of the cerebral arteries that can occur after a spontaneous aneurysmal subarachnoid hemorrhage (SAH). Despite a large number of experimental and clinical investigations, the exact pathophysiology of vasospasm remains unknown. Using a fluorescence differential-display system, we have identified the gene encoding heat shock p...

Abstract Introduction Cerebral inflammation in bacterial meningitis has been associated with vasospasms of cerebral arteries and arterioles. Vasospasm has been associated with permanent neurological deficits and death. The objective of the review was to summarise evidence for the involvement of inflammatory mediators in the pathogenesis of cerebral vasospasm. Materials and methods Databases Pub...

The performance of transcranial Doppler in the detection of anterior cerebral artery vasospasm and vasospasm in patients after subarachnoid haemorrhage was analysed. Transcranial Doppler and cerebral angiography were performed within the same 24 hours on each of 41 patients with acute subarachnoid haemorrhage. Sensitivity and specificity of transcranial Doppler to classify middle cerebral arter...

Rabies encephalitis is a uniformly fatal disease with several hypothesis proposed to explain pathogenesis and mortality. One such theory premises deficiency of neuronal nitric oxide synthetase deficiency causing selective cerebral vasospasm. We present transcranial Doppler findings in a case of rabies that did not show imaging evidence of vasospasm. Transcranial Doppler in two published cases h...

BACKGROUND Transcranial Doppler (TCD) is used to monitor cerebral vasospasm after subarachnoid hemorrhage (SAH), but its diagnostic ability is reported to be limited. Therefore, the purpose of this study was to investigate the relationship between the diagnosability of TCD and the localization of the vasospasm. METHODS This retrospective study included 20 patients who presented with symptomat...

INTRODUCTION Cerebral vasospasm is a major cause of delayed ischemic cerebral injury, typically occurring 3-14 days after subarachnoid hemorrhage (SAH). Ultra-early vasospasm is defined as angiographic vasospasm observed within 48 h of SAH onset. Immediate vasospasm at the time of aneurysmal rupture has been suspected, but has not been previously reported. We describe a case of immediate, trans...

CHRISTOPHER W. NORWOOD, G. JOSEPH POOLE, DIXON MOODY, and EBEN ALEXANDER, Jr (Winston-Salem) noted that a successful treatment for delayed cerebral vasospasm after subarachnoid haemorrhage had been reported. In their Rhesus monkey population subjected to subarachnoid haemorrhage 62.5% developed delayed cerebral vasospasm. Seven were treated with a beta-adrenergic drug alone, and five of the sev...

BACKGROUND AND PURPOSE Cerebral microcirculatory changes during cerebral vasospasm after aneurysmal subarachnoid hemorrhage (SAH) are still controversial and uncertain. The aim of this study was to investigate the changes of cerebral microcirculation during cerebral vasospasm and to clarify the roles of microcirculatory disturbances in cerebral ischemia by measuring cerebral circulation time (C...
