Automated Large Vessel Occlusion Detection Software and Thrombectomy Treatment Times
This study attempts to determine whether automated computed tomography angiogram interpretation coupled with secure group messaging can improve in-hospital endovascular stroke therapy workflows.

Disentangling Workflow Paradigms and Treatment Decision-Making in Acute Ischemic Stroke —Reply
In Reply We thank Ospel and Goyal for their interest in the Evaluation of Direct Transfer to Angiography Suite vs Computed Tomography Suite in Endovascular Treatment (ANGIOCAT) study and read with interest their letter in which they express some concerns in relation to the direct-to-angiography suite (DTAS) paradigm. In the ANGIOCAT study, patients adjudicated to the conventional imaging group, despite receiving computed tomography perfusion (CTP) in some cases, achieved one of the shortest workflow times reported ever (door-to-puncture time of 44 minutes). According to guidelines, CTP was never used to exclude patients fr...

Questions on Predicting Early Neurological Deterioration in Patients With Minor Stroke and Large-Vessel Occlusion —Reply
In Reply We thank Ospel and colleagues for their thoughtful comments on our article showing that more proximal occlusion and greater thrombus length predict early neurological deterioration of ischemic origin (ENDi) in patients with acute minor ischemic stroke with large-vessel occlusion treated with intravenous thrombolysis, with implications regarding how to best manage these patients. Although the precise pathophysiological links between more proximal occlusion, a longer thrombus, and ENDi are uncertain, we fully agree that a leading hypothesis is in situ thrombus extension leading to secondary hemodynamic compromise vi...

Streamlining the Path to Endovascular Reperfusion
In this issue of JAMA Neurology, Sarraj et al report on the associations of repeated imaging on arrival at an endovascular thrombectomy (EVT) –capable hospital with clinical outcomes after EVT. They studied an observational cohort of 2533 patients who had ischemic stroke with large vessel occlusion within 24 hours of stroke onset. It is well understood that a favorable outcome depends on the time from stroke onset to reperfusion, and th ere is no doubt that proceeding directly to the angiography suite (DTA) saves time compared with repeating imaging (median time, 26 minutes shorter in Sarraj et al). Direct transfer to th...

Left Atrial Enlargement Could Be Detected on Extended Computed Tomography Angiography —Reply
In Reply We agree with Popkirov that left atrial volume is a better marker of incident atrial fibrillation than atrial diameter; however, we did not have these data available at all of the sites participating in the New Approach Rivaroxaban Inhibition of Factor Xa in a Global Trial Versus ASA to Prevent Embolism in Embolic Stroke of Undetermined Source (NAVIGATE-ESUS) trial. Recently completed and ongoing studies will help determine if our observation has a clinical role and may provide additional data on left atrial size and function. Once all of these data are available, guidelines committees will likely make recommendat...

Response to Endovascular Therapy for Acute Ischemic Stroke
To the Editor Recent data from randomized clinical trials provide clear evidence that endovascular treatment for acute ischemic stroke because of large vessel anterior circulation occlusion improves clinical outcomes for patients. These studies reported that most patients had an occlusion of the first segment (M1) of the middle cerebral artery and less than 10% in the M2 segment. The retrospective multicenter study conducted by Sarraj et al reports that endovascular treatment is safe and effective for an occlusion of the M2 segment. However, the literature reports different definitions for the M1 and M2 segments, which may...
