Background And Aims: Stroke is a leading cause of death in Aotearoa (New Zealand), and stroke reperfusion therapy is a key intervention. Sex differences in stroke care have previously been asserted internationally. This study assessed potential differences in stroke reperfusion rates and quality metrics by sex in Aotearoa (New Zealand).

We present a man in his late 60s who presented with diplopia, dysarthria and right-sided limb weakness. This syndrome is one of a group of 'crossed paralyses' of the caudal pons.

These are important to recognise due to their different management, which is often specific and effective, and due to their different prognosis from otherwise cryptogenic ischaemic strokes. We outline a practical approach to identifying uncommon causes of ischaemic stroke by highlighting diagnostic 'red flags' and propose a structured approach to investigating them.

- The study investigates the prevalence and characteristics of dural arteriovenous fistulas (dAVFs) in patients with cerebral venous thrombosis (CVT), finding that 2.4% of CVT patients had dAVFs.
- It highlights that patients with dAVFs tend to be older, predominantly male, and more likely to experience chronic CVT onset, with specific imaging findings.
- Despite these associations, the clinical outcomes for patients with and without dAVFs were similar, with most fistulas identified either at the time of CVT diagnosis or afterward.
Article Synopsis
- A study examined late seizures (LS) after cerebral venous thrombosis (CVT) using data from 1,127 patients, focusing on their occurrence, characteristics, treatment, and predictors.
- About 11% of patients experienced LS during a median follow-up of 2 years, with the first seizure usually happening around 5 months post-CVT diagnosis.
- Key predictors for developing LS included having status epilepticus during the acute phase, undergoing decompressive hemicraniectomy, and experiencing acute seizures, highlighting a significant risk for recurrence which suggests the need for a proper epilepsy diagnosis.
Objective: To identify characteristics, predictors, and outcomes of acute symptomatic seizures (ASS) in cerebral venous thrombosis (CVT), we investigated 1,281 consecutive adult patients with CVT included from 12 hospitals within the International CVT Consortium.
Methods: We defined ASS as any seizure between symptom onset and 7 days after diagnosis of CVT. We stratified ASS into prediagnosis and solely postdiagnosis ASS.
