In an ideal world, a vascular neurologist excludes contraindications and starts treatment the minute a stroke occurs. While the first minute seems unrealizable, the first hour is not. Considerable time savings have been achieved with specialized stroke ambulances equipped with a computed tomography system and a neurologist on board. However, these specialized ambulances come at a certain cost, especially personnel costs. Can telemedicine replace the physical presence of a physician in a prehospital stroke setting?

Purpose: Many patients with ischemic stroke have concomitant coronary artery disease (CAD). However, it remains unclear which stroke patients should undergo evaluation for asymptomatic CAD, and which screening tools are appropriate. We investigated the role of coronary artery calcium (CAC) score as a screening tool for asymptomatic but severe CAD in acute stroke patients. We determined the selection criteria for CAC screening based on risk factors and cerebral atherosclerosis.Materials and Methods: The present study included consecutive patients with acute stroke who had undergone cerebral angiography and multi-detector co...

By STEPHEN BORSTELMANN, MD Occasionally, you get handed a question you know little about, but it’s clear you need to know more.  Like most of us these days, I was chatting with my colleagues about the novel coronavirus. It goes by several names: SARS-CoV-2, 2019-nCoV or COVID-19 but I’ll just call it COVID.  Declared a pandemic on March 12, 2020 by the World Health Organization (WHO), COVID is diagnosed by laboratory test – PCR.  The early PCR test used in Wuhan was apparently low sensitivity (30-60%), lengthy to run (days), and in short supply.  As CT scanning was relatively availa...

ConclusionLower LMR was independently related to higher risk of HT in patients with AIS. Admission LMR may be used as one of the predictors for HT. Further prospective multicenter studies are needed to validate our findings.

In patients with non-valvular atrial fibrillation (AF) and increased stroke risk, the left atrial appendage (LAA) is a primary source of thrombus [1]. Percutaneous left atrial appendage closure (LAAC), a minimally invasive procedure, is increasingly performed to reduce AF stroke risk [1]. For successful clinical outcomes, it is therefore imperative that the Watchman implant —one such LAA closure device—maintains long-term efficacy. The PROTECT-AF trial, for instance, reported peridevice leak in 32% of patients post-LAAC.

ConclusionsThis retrospective study suggests that SHPD may play a protective role in HT appearance and evolution, which requires verification by a randomized clinical trial.

We administered intravenous thrombolytic therapy to a 51-year-old female patient with a 101-min stroke onset. The patient was unconscious during the manifestation of symptoms. Computed tomography angiography examination of the intracranial artery at the time of admission suggested that the left middle cerebral artery was occluded. The patient regained consciousness after the intravenous thrombolytic treatment was administered. On an urgent cerebral angiography, it was revealed that the recanalization of the left middle cerebral artery was successful.

Abstract OBJECTIVE: We performed a meta-analysis to evaluate the agreement of cardiac computed tomography (CT) with cardiac magnetic resonance imaging (CMRI) in the assessment of right ventricle (RV) volume and functional parameters. MATERIALS AND METHODS: PubMed, EMBASE, and Cochrane library were systematically searched for studies that compared CT with CMRI as the reference standard for measurement of the following RV parameters: end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), or ejection fraction (EF). Meta-analytic methods were utilized to determine the pooled weighted bias, lim...

AbstractMost of the acute ischemic events, such as acute coronary syndromes and stroke, are attributed to vulnerable plaques. These lesions have common histological and pathophysiological features, including inflammatory cell infiltration, neo-angiogenesis, remodelling, haemorrhage predisposition, thin fibrous cap, large lipid core, and micro-calcifications. Early detection of the presence of a plaque prone to rupture could be life-saving for the patient; however, vulnerable plaques usually cause non-haemodynamically significant stenosis, and anatomical imaging techniques often underestimate, or may not even detect, these ...
