Ten-Year Evaluation of the TOYOTA Prehospital Stroke Scale for Tissue Plasminogen Activator Intravenous Therapy in the Real World.
Emergency medical services are an important part of acute stroke management. We devised a prehospital stroke scale, the TOYOTA prehospital stroke scale for tissue plasminogen activator (t-PA) intravenous therapy (TOPSPIN) for triaging patients with ischemic stroke and especial indications for intravenous t-PA therapy in December 2006; this scale comprises 5 items including consciousness, atrial fibrillation, language disorder, disturbance of the upper extremities, and disturbance of the lower extremities. The aim of this study was to analyze the results of 10 years of TOPSPIN implementation and to distinguish ischemic stroke from hemorrhagic stroke in the real world. ⋯ The TOPSPIN is a simple prehospital stroke scale that includes an assessment of atrial fibrillation. Detection of atrial fibrillation in the prehospital stage may point to a higher probability of ischemic stroke.

Observational StudyEndotracheal Intubation and In-Hospital Mortality after Intracerebral Hemorrhage.
Many patients with acute intracerebral hemorrhages (ICHs) undergo endotracheal intubation with subsequent mechanical ventilation (MV) for "airway protection" with the intent to prevent aspiration, pneumonias, and its related mortality. Conversely, these procedures may independently promote pneumonia, laryngeal trauma, dysphagia, and adversely affect patient outcomes. The net benefit of intubation and MV in this patient cohort has not been systematically investigated. ⋯ In this large hospital-based cohort of patients presenting with an acute spontaneous ICH, endotracheal intubation and MV were associated with increased odds of HAP and HM. These findings urge further examination of the practice of intubation in prospective studies.

Observational StudyPredictors for Mortality after Mechanical Thrombectomy of Acute Basilar Artery Occlusion.
Modern endovascular thrombectomy (MET), using stent retrievers or large-bore distal aspiration catheters in stroke patients with acute basilar artery occlusion (BAO), is routinely performed to date. However, more than 35% of BAO patients treated with MET die within 90 days despite high recanalization rates. The purpose of this study is to investigate the parameters associated with 90-day mortality in patients with BAO after MET. ⋯ Failure of successful recanalization was a strong predictor for mortality. In the setting of recanalization, age, admission NIHSS, pc-ASPECTS, absence of intravenous thrombolysis, and angioplasty/stenting of the basilar artery were also independent predictors for mortality after MET of BAO patients.

Observational StudyMechanical Thrombectomy in Acute Stroke Due to Carotid Occlusion: A Series of 153 Consecutive Patients.
Strokes due to carotid artery occlusion (CAO) are associated with bad clinical prognosis and poor response to intravenous thrombolysis. Several studies in the past have shown the benefits of mechanical thrombectomy (MT) and compared bridging therapy (BT) and primary MT (PMT) in large vessel occlusions, but only a few studies have focused on the specific population of CAO and their response to endovascular treatment. ⋯ In our population, patients with CAO clinically present with severe strokes. Isolated occlusions of the extra- or intracranial segments of the carotid are more frequent than tandem occlusions. Successful recanalization after thrombectomy is achieved in most of the patients, but association with favorable functional outcome is poor. Clinical evolution is similar in patients treated with PMT and BT. Intracranial symptomatic hemorrhage after treatment is associated with higher intrahospital mortality and worse 3 months-mRS. Poor perfusion-CT mismatch, symptomatic hemorrhage, and isolated CAO are independent predictors of intrahospital mortality. Admission NIHSS is an independent predictor of 3 months-mRS.

Natural History of Cervical Artery Fibromuscular Dysplasia and Associated Neurovascular Events.
Fibromuscular dysplasia (FMD) is a non-atherosclerotic arteriopathy most often affecting the carotid and renal arteries. In the United States Registry for FMD, 41.7% of patients experienced an aneurysm and/or dissection by the time of entry into the Registry. We sought to determine the occurrence of neurovascular events after FMD diagnosis and any changes on cervical artery imaging that may be attributable to FMD. ⋯ No new cervical artery FMD or aneurysm was observed on subsequent imaging. New carotid dissection was uncommon over a mean follow-up period of 35.3 ± 25.3 months and was the only non-atherosclerotic vascular event observed after FMD diagnosis.
