Article Synopsis
- The quality of leptomeningeal collaterals can affect how quickly brain tissue is damaged during an acute stroke, with the study aiming to explore the relationship between collateral scores and ischemic changes seen on CT scans.
- Adult patients with acute stroke symptoms were analyzed based on their collateral scores and imaging results, using statistical models to assess the impact of these scores over time.
- Findings showed that patients with low collateral scores (0-1) had worse imaging outcomes (lower ASPECTS), and the relationship between time passed since stroke and collateral scores highlighted the importance of early intervention.
Objective: To determine the safety and efficacy of balloon vs sham venoplasty of narrowing of the extracranial jugular and azygos veins in multiple sclerosis (MS).
Methods: Patients with relapsing or progressive MS were screened using clinical and ultrasound criteria. After confirmation of >50% narrowing by venography, participants were randomized 1:1 to receive balloon or sham venoplasty of all stenoses and were followed for 48 weeks.
