Missed Ischemic Stroke Diagnosis in the Emergency Department by Emergency Medicine and Neurology Services.
The failure to recognize an ischemic stroke in the emergency department is a missed opportunity for acute interventions and for prompt treatment with secondary prevention therapy. Our study examined the diagnosis of acute ischemic stroke in the emergency department of an academic teaching hospital and a large community hospital. ⋯ Atypical symptoms associated with posterior circulation strokes lead to misdiagnoses. This was true at both an academic center and a large community hospital. Future studies need to focus on the evaluation of identification systems and tools in the emergency department to improve the accuracy of stroke diagnosis.

Pregnancy and puerperium are associated with an increased risk of venous thrombotic events (VTEs), including cerebral venous thrombosis (CVT). We aimed to systematically review, in pregnant woman with previous CVT, (1) the risk of recurrence of CVT or other VTE; (2) the result of pregnancy; and (3) the association of antithrombotic prophylaxis with these outcomes. ⋯ In women with previous CVT, the absolute risk of pregnancy-related venous thrombosis is low but the relative risk of noncerebral VTE is 16-fold higher and the recurrence of CVT is 80-fold higher than the baseline risk described in general population studies. The rate of miscarriage is not significantly different from that estimated for the general population.

Flow diversion using the Pipeline Embolization Device is reported as a safe treatment of aneurysms. Complete aneurysm occlusion, however, occurs in a delayed fashion with initial persistent filling of the aneurysm dome. We hypothesized that this transflow across metallic struts may be associated with thromboembolic events. ⋯ The Pipeline Embolization Device is associated with increased rate of de novo FLAIR lesions occurring in a delayed fashion and distinct from perioperative diffusion-weighted imaging lesions. The cause and clinical effect of these lesions are unknown and suggest the need for prudent follow-up and evaluation.

Clinical and Procedural Predictors of Outcomes From the Endovascular Treatment of Posterior Circulation Strokes.
Patients with posterior circulation strokes have been excluded from recent randomized endovascular stroke trials. We reviewed the recent multicenter experience with endovascular treatment of posterior circulation strokes to identify the clinical, radiographic, and procedural predictors of successful recanalization and good neurological outcomes. ⋯ Time to the start of the procedure is an important predictor of clinical success after thrombectomy in patients with posterior circulation strokes. Both stent retriever and aspiration thrombectomy as primary treatment approaches are effective in achieving successful recanalization.

Assessment of Home-Time After Acute Ischemic Stroke in Medicare Beneficiaries.
Stroke survivors have identified home-time as a meaningful outcome. We evaluated home-time as a patient-centered outcome in Medicare beneficiaries with ischemic stroke in comparison with modified Rankin Scale (mRS) score at 90 days and at 1 year post event. ⋯ In a population of older patients with ischemic stroke, home-time was readily available from administrative data and associated with mRS at 90 days and 1 year. Home-time represents a novel, easily measured, patient-centered, outcome measure for an episode of stroke care.
