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...

Do Patients with Retinal Artery Occlusion Need Urgent Neurological Evaluation?
Whether patients with central (CRAO) or branch (BRAO) retinal artery occlusion should undergo urgently a detailed neurological workup for ischemic stroke is controversial. In a survey1 of physicians in the United States, among those who responded, 35% of ophthalmologists but 73% to 86% of neurologists and neuro-ophthalmologists sent their patients with acute CRAO for immediate neurological workup. An anonymous survey of members of the American Academy of Neurology Stroke Section and vitreoretinal specialists of the American Academy of Ophthalmology showed that 75% neurologists pursue a hospital-based evaluation within 12 h...
