Intra-arterial revascularisation therapy for acute ischaemic stroke: initial experience in a Hong Kong hospital.

Objectives: To assess the outcome of acute ischaemic stroke patients who received intra-arterial therapy in our unit.

Design: Case series.

Setting: A tertiary hospital in Hong Kong.

Multimodal computed tomography evaluation before thrombolysis in acute ischaemic stroke.

Currently, when stroke patients are offered thrombolytic therapy, their ischaemic stroke subtypes are usually unknown. Given the risk of haemorrhage that accompanies thrombolytic therapy, unselective (or undiscriminating) use of recombinant tissue plasminogen activator in patients without large-artery thromboemboli is potentially hazardous. Advances in computed tomography techniques have enabled the stroke pathophysiology to be quickly delineated by multimodal computed tomography without compromise in time for recombinant tissue plasminogen activator administration.

Potential value of post stroke extracranial arterial blood flow volume in the prediction of stroke functional outcome.

Background And Purpose: Cerebral vasoreactivity and collateral circulation are important protective mechanisms against cerebral ischemia. Previous studies suggest that the efficiency of these mechanisms can be reflected by extracranial arterial blood flow volume. Brain damage leading to neurological impairments can influence patients' functional recovery after stroke.
