Comparison of multimodal CT scan protocols used for decision-making on mechanical thrombectomy in acute ischemic stroke

ConclusionAdding CTP and/or a delayed-phase CTA to NCCT with arterial-phase CTA improves the decision-maker ’s confidence level and creates a trend towards a lower threshold for mechanical thrombectomy.

Abstract AIM OF THE STUDY: The aim of the study was to evaluate the clinical characteristics of patients with previous stroke (either ischemic or hemorrhagic), who developed status epilepticus (SE) mimicking a stroke relapse. MATERIALS AND METHODS: We performed a retrospective cohort study of patients brought to hospital by the emergency service between December 2016 and January 2018 with a stroke code as possible candidates for intravenous thrombolysis and who had already have a previous stroke. Among them, patients admitted for negative symptoms and finally discharged with a diagnosis of SE mimicking stroke...

AbstractThis technical note describes a novel CT scan protocol that includes a non-enhanced CT, dynamic CTA, and perfusion of the whole brain and CTA of the carotid arteries using a 320-row area detector CT scanner, with a unique contrast injection and acceptable radiation exposure dose in patients presenting with acute ischemic stroke. The acquisition parameters and reconstruction parameters will be discussed including the use of model-based iterative reconstruction (MBIR), time summing (tMIP), and subtraction techniques to optimize the results of this protocol.Key Points• Scanning on a 320-row area detector CT can a...

iSchemaView today announced that it received registration approval in Japan for its Rapid imaging platform. The company received registration approval through the Japanese Pharmaceutical Affairs Law and through a third party review by the Japanese Assn. for the Advancement of Medical Equipment for the Rapid imaging platform. Rapid is designed to give physicians a fast, fully automated and easy-to-interpret imaging system that can help doctors make clinical decisions about stroke. “Stroke remains the fourth most common cause of death in Japan, and as the population ages, stroke is likely to become an increasing health...

Authors: Campbell BC Abstract In recent years, reperfusion therapies such as intravenous thrombolysis and endovascular thrombectomy for ischaemic stroke have dramatically reduced disability and revolutionised stroke management. Thrombolysis with alteplase is effective when administered to patients with potentially disabling stroke, who are not at high risk of bleeding, within 4.5 hours of the time the patient was last known to be well. Emerging evidence suggests that other thrombolytics such as tenecteplase may be even more effective. Treatment may be possible beyond 4.5 hours in patients selected using brain imagi...

This article presents an overview on recent advances in optical non-invasive diagnostics of the peripheral hemodynamics of the upper and lower limbs in rheumatological and endocrinological profile patients. Among these are laser Doppler flowmetry (LDF), tissue reflectance oximetry (TRO), pulse oximetry (PO) and fluorescent spectroscopy (FS). The laser Doppler flowmetry method allows for investigating the blood flow in the microcirculatory bed in vivo. The method is based on probing the tissue with laser radiation and analyzing back reflected from the tissue radiation partially scattered from moving red blood cells (Bonner...

Conclusion: Postreperfusion BP management by decreasing BPV may have influence on improving clinical outcome in cases of poor collateral circulation among patients achieving successful recanalization after ERT. Introduction Endovascular recanalization therapy (ERT) has been adopted as standard stroke care in patients with acute ischemic stroke (1–6). Time to recanalization and degree of recanalization are the most important predictors of clinical outcomes after ERT (7). Before recanalization, an effort to reduce the time from symptom onset to reperfusion is critical for penumbral salvage. After recanalization, ...

I was shown this ECG with no other information:What do you think?Hint: try to see through the artifact!I answered immediately: " High lateral MI with posterior MI. OMI. " (Occlusion Myocardial Infarction)I asked, " Did the patient present with chest pain? "Here is the history:" A middle-aged male complained of about 18 hours of epigastric pain that radiated to the chest.  He also had an apparently new facial droop of equal duration.  A stroke code was called, NIH stroke scale was only 1, and attention was turned to the chest pain. "  BP was 148/83.How did I make this ECG diagnos...
