BACKGROUND AND PURPOSE Intravenous thrombolysis is an approved treatment for anterior (ACS) and posterior (PCS) circulation stroke. However, no randomized controlled trial has investigated safety and efficacy of intravenous thrombolysis according to stroke territory, although PCS is assumed to differ from ACS in many ways. We aimed to compare the safety and clinical outcome of intravenous throm...
PURPOSE In the present study, we aimed to investigate the frequency of blood brain barrier injury in posterior circulation infarction as demonstrated by the hyperintense acute reperfusion marker (HARM) on fluid attenuated inversion recovery images (FLAIR). METHODS From a MRI report database we identified patients with posterior circulation infarction who underwent MRI, including perfusion-wei...
Neurological deficits can occur following snake bite. It is usually due to intracerebral haemorrhage or subarachnoid bleed as a result of depletion of clotting factors. A healthy 14-years-old male developed bilateral ptosis and altered sensorium within 3 hours of snake bite. CT Brain revealed bilateral cerebellar and right occipital infarction with mass effect. Clotting time and bleeding time w...

We aimed to identify factors contributing to outcome measures in patients treated with the Surpass flow diverter for aneurysms in this location. MATERIALS AND METHODS We conducted an observational study of 53 patients who underwent flow-diverter treatment for posterior circulation ...
