It is recognized that anticoagulants should be withdrawn before surgery or invasive tests for the recommended period. However, it is not well known when anticoagulants should restart. For the past 12 months, we had 5 patients who suddenly developed ischemic stroke after a prolonged withdrawal of anticoagulants for atrial fibrillation.… Read More...

We thank Drs. Lahiri and Lyden for their valuable comments regarding the benefit of hemicraniectomy in patients over the age of 60 years. As the authors mentioned, there was a trend toward higher odds of favorable outcome (modified Rankin Scale scores of 0-3) among those randomized to hemicraniectomy compared with conservative treatment in trials that permitted recruitment of patients aged 60 years or older (303 subjects analyzed; odds ratio 1.87, 95% confidence interval .91-3.86, P = .09).… Read More...

The aim of this study was to evaluate the effectiveness of mechanical aspiration thrombectomy (MAT) in patients with acute ischemic stroke from calcified cerebral emboli.

The purpose of this study was to calculate the burden of 3 major diseases (cancer, heart disease, and cerebrovascular disease [CVD]) using the cost of illness (COI) method.

Magnetic resonance (MR) and contrast-enhanced ultrasound assess characteristics and neovascularization, respectively, of the carotid plaque. The purpose of the present study was to clarify how findings of contrast-enhanced ultrasound plaque imaging are related to those of 3-dimensional (3D) fast spin echo (FSE) T1-weighted MR plaque imaging (WI) in severe stenosis (≥70%) of the cervical carotid artery.… Read More...

The purpose of our work is to quantitatively assess clinically relevant geometric properties of proximal middle cerebral arteries (pMCA), to investigate the degree of their lateral symmetry, and to evaluate whether the pMCA can be modeled by using state-of-the-art deformable image registration of the ipsi- and contralateral hemispheres.… Read More...

Detection of paroxysmal atrial fibrillation (PAF) in cryptogenic stroke is critical to selecting an antithrombotic therapy for preventing recurrent stroke. However, the predictor of PAF in patients with acute ischemic stroke is not well elucidated. P-wave terminal force in lead V1 (PTFV1) is a standard electrocardiogram marker of left atrial abnormality.… Read More...

Stroke is a critical public health issue in the United States and globally. System models to optimally capture stroke incidence in rural and culturally diverse communities are needed. The epidemiological transition to a western lifestyle has been associated with an increased burden of vascular risk factors among Alaska Native (AN) people.… Read More...
