OBJECTIVE Identification of patients with aneurysmal subarachnoid haemorrhage (aSAH) with cognitive impairment is important for patient management (medical treatment, cognitive rehabilitation and social arrangements). The Montreal cognitive assessment (MoCA) is currently recommended over the mini-mental state examination (MMSE) by the U.S. National(More)
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(More)
BACKGROUND We have investigated the impact of primary decompressive craniectomies on neurological outcomes after adjusting for other predictive variables. METHOD We have collected data from trauma patients with acute subdural hematomas in a regional trauma center in Hong Kong over a 4-year period. Patient risk factors were investigated using logistic(More)
BACKGROUND AND PURPOSE Pilot clinical trials using magnesium sulfate in patients with acute aneurysmal subarachnoid hemorrhage have reported trends toward improvement in clinical outcomes. This Phase III study aimed to compare intravenous magnesium sulfate infusion with saline placebo among such patients. METHODS We recruited patients with aneurysmal(More)
BACKGROUND Clinical prediction models can enhance clinical decision-making and research. However, available prediction models in aneurysmal subarachnoid hemorrhage (aSAH) are rarely used. We evaluated the methodological validity of SAH prediction models and the relevance of the main predictors to identify potentially reliable models and to guide future(More)
BACKGROUND Reported infection rates after ventriculoperitoneal shunt surgery vary from 1 to 25%. Antibiotic-impregnated (AI) catheters may reduce shunt infection rates, but this is uncertain. OBJECTIVE To establish a prospective shunt registry to evaluate short-term (3-month) infection rates associated with ventriculoperitoneal shunts and standard or AI(More)
BACKGROUND AND PURPOSE After aneurysmal subarachnoid hemorrhage (aSAH), cognitive impairment, even mild and relatively isolated, can be devastating, especially in working-age persons. The Montreal Cognitive Assessment (MoCA) is accepted as a valid screening tool for mild cognitive impairment due to cerebral ischaemia. Whether MoCA is independently(More)
PURPOSE To evaluate the midterm clinical and angiographic outcomes after pipeline embolization device (PED) placement for treatment of intracranial aneurysms. MATERIALS AND METHODS This prospective nonrandomized multicenter study was approved by the review boards of all involved centers; informed consent was obtained. Patients (143 patients, 178(More)
The outcome of patients with aneurysmal subarachnoid hemorrhage (SAH) has improved slowly over the past 25 years. This improvement may be due to early aneurysm repair by endovascular or open means, use of nimodipine, and better critical care management. Despite this improvement, mortality remains at about 40%, and many survivors have permanent neurologic,(More)
OBJECT Traumatic subarachnoid hemorrhage (SAH) is a poor prognostic factor for traumatic brain injury. The authors aimed to further investigate neurological outcome among head injury patients by examining the prognostic values of CT patterns of traumatic SAH, in particular, the thickness and distribution. METHODS The study was conducted using a database(More)
