Carotid Stenting—Why Treating an Artery May Not Treat the Patient
In this issue of JAMA Neurology, Jalbert and colleagues present the results of a detailed analysis of Centers for Medicare & Medicaid Services (CMS) administrative data on patients with carotid artery stenosis treated with carotid artery stenting. Their well-written manuscript and timely study included more than 22 000 patients treated and followed up between 2000 and 2009. They analyzed periprocedural complications (defined as stroke, transient ischemic attack [TIA], myocardial infarction [MI], and death within 30 days), as well as long-term stroke and mortality. Important variables that were analyzed included the degre...

Outcomes After Carotid Artery Stenting in Medicare Beneficiaries, 2005 to 2009
Conclusions and RelevanceCompeting risks may limit the benefits of CAS in certain Medicare beneficiaries, particularly among older and symptomatic patients who have higher periprocedural and long-term mortality risks. The generalizability of trials like the SAPPHIRE or CREST to the Medicare population may be limited, underscoring the need to evaluate real-world effectiveness of carotid stenosis treatments.

Cerebral Microbleeds and Early Recurrent Stroke After Transient Ischemic Attack Results from the Korean Transient Ischemic Attack Expression Registry
Conclusions and RelevanceImmediate and optimal management seems to modify the risk of recurrent stroke after TIA. Cerebral microbleeds may be novel predictors of stroke recurrence, which needs further validation.

Implementing a Mobile Stroke Unit Program in the United States Why, How, and How Much?
Conclusions and RelevanceThe MSU strategy could dramatically transform the way acute stroke is managed in the United States. A prospective study evaluating the logistics, outcomes, and cost-effectiveness of this approach is needed and under way.

Prehospital Thrombolysis for Stroke An Idea Whose Golden Hour Has Arrived
Soon after thrombolytic therapy was established as a therapy for ischemic stroke, our colleague Anthony Furlan, MD, famously circulated a cartoon of a computed tomographic (CT) scanner visible through the back doors of an ambulance, where a happy stroke physician had hung a bottle dripping tissue plasminogen activator (tPA) into the scanned patient’s arm. Because the time interval from stroke onset to initiation of thrombolysis after ischemic stroke is inversely related to the probability of disability-free recovery, prehospital initiation of thrombolytic therapy seemed a compelling and logical ambition, if one could rul...

Effects of Golden Hour Thrombolysis A Prehospital Acute Neurological Treatment and Optimization of Medical Care in Stroke (PHANTOM-S) Substudy
ImportanceThe effectiveness of intravenous thrombolysis in acute ischemic stroke is time dependent. The effects are likely to be highest if the time from symptom onset to treatment is within 60 minutes, termed the golden hour.ObjectiveTo determine the achievable rate of golden hour thrombolysis in prehospital care and its effect on outcome.Design, Setting, and ParticipantsThe prospective controlled Prehospital Acute Neurological Treatment and Optimization of Medical Care in Stroke study was conducted in Berlin, Germany, within an established infrastructure for stroke care. Weeks were randomized according to the availabilit...
