Stenosis Length and Degree Interact With the Risk of Cerebrovascular Events Related to Internal Carotid Artery Stenosis
Conclusion: We found a statistically insignificant tendency for the ultrasound-measured length of sICAS<70% to be longer than that of sICAS≥70%. Moreover, the ultrasound-measured length of sICAS<90% was significantly longer than that of sICAS 90%. Among patients with sICAS≥70%, the degree and length of stenosis were inversely correlated. Larger studies are needed before a clinical implication can be drawn from these results. Introduction Internal carotid artery stenosis (ICAS) causes around one-fifth of ischemic cerebrovascular stroke and has the highest risk of early stroke recurrence...

Asymptomatic Carotid Stenosis Is Associated With Circadian and Other Variability in Embolus Detection
Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this t...

Pediatric Moyamoya Syndrome Secondary to Tuberculous Meningitis: A Case Report
We report the case of a female patient who initially presented at 6 years of age with TBM and developed moyamoya syndrome requiring revascularization surgery. Results She was found to have basilar meningeal enhancement and right basal ganglia infarcts. She was treated with 12 months of antituberculosis therapy and 12 months of enoxaparin and maintained on daily aspirin indefinitely. However, she developed recurrent headaches and transient ischemic attacks and was found to have progressive bilateral moyamoya arteriopathy. At age 11 years, she underwent bilateral pial synangiosis for the treatment of her moyamoya syndrome. ...
