Functional outcome after subarachnoid haemorrhage has traditionally been assessed using scales developed for other neurological conditions. The modified Rankin score and Glasgow Outcome Scale are most commonly used. Employment of these scales in subarachnoid haemorrhage is hampered by well recognized limitations. We set out to develop and validate a new condition-specific subarachnoid haemorrha...

OBJECTIVE To evaluate the influence of meteorological factors on the onset of aneurysmal subarachnoid haemorrhage in Hong Kong. DESIGN Retrospective review of prospectively collected data. SETTING University teaching hospital, Hong Kong. PATIENTS A total of 135 consecutive patients with acute aneurysmal subarachnoid haemorrhage presenting to the hospital within 48 hours after ictus from O...

cerebral vasospasm considered to be a serious cause of morbidity and mortality following subarachnoid haemorrhage (sah).despite several available therapeutic options, current protocols do not prevent major consequences of vasospasm. inflammation is believed to play an important role in post-haemorrhagic vasospasm. meloxicam is a non-steroidal anti-inflammatory drug. the aim of this study was to...

Perimesencephalic subarachnoid haemorrhage is usually asymptomatic other than meningeal irritation sign. The authors report a case of subarachnoid haemorrhage at the quadrigeminal cistern showing ipsilateral trochlear nerve palsy and discuss the pathogenesis. A 71-year-old man with a history of diabetes mellitus and acute myocardial infarction presented with diplopia. He underwent CT, which rev...

OBJECTIVE To review systematically the frequency and prognostic significance of vitreous haemorrhage in patients with subarachnoid haemorrhage (Terson's syndrome). METHODS Papers relating to vitreous haemorrhage in patients with subarachnoid haemorrhage were retrieved. The only studies considered were those with at least 10 consecutive cases of subarachnoid haemorrhage with or without vitreou...

Isolated angiitis of the CNS (IACNS) commonly presents with recurrent ischaemic or haemorrhagic infarcts, but subarachnoid haemorrhage is rare. Three patients with IACNS and subarachnoid haemorrhage are reported. Florid granulomatous angiitis with Langhans and foreign body type giant cells was found at necropsy in a child with sudden death. In two other patients the diagnosis was made angiograp...

OBJECTIVE To estimate the risk of occurrence of subarachnoid haemorrhage in first degree relatives (parents, siblings, children) of patients with subarachnoid haemorrhage. DESIGN Population based cohort study using data from the Danish National Discharge Registry and the Central Person Registry. SUBJECTS Incident cases of subarachnoid haemorrhage admitted to hospital from 1977 to 1995 (9367...

Aneurysmal subarachnoid haemorrhage is one of the most deleterious acute neurological diseases. The cerebral ischemia secondary to arterial vasospasm occurring after aneurysmal subarachnoid haemorrhage is still responsible for the considerable morbidity and mortality in these patients. Besides the knowledge of basic mechanisms of cerebral vasoespasm following aneurysmal subarachnoid haemorrhage...

Daily estimations of hemispheral cerebral blood flow using the xenon-133 inhalation technique was made in 116 patients during the first three weeks after subarachnoid haemorrhage. The patients' cerebral perfusion on average remained less than the normal perfusion expected for their age (based on a single estimation of cerebral blood flow in 67 volunteers). On each separate day after subarachnoi...
