Association of fluid-attenuated inversion recovery vascular hyperintensity with ischaemic events in internal carotid artery or middle cerebral artery occlusion

Character and purpose Individuals with intracranial artery occlusion have a high incidence of ischaemic events and recurrence. In the asymptomatic occlusion group, the FVH-ASPECTS was much lower than in the symptomatic occlusion group than in the symptomatic occlusion group. Conclusions The ability to distinguish symptomsatic from asymptomatic occlusion using FVH-ASPECTS indicates that FVH may be a predictor of stroke. FVH can be used as a surrogate for hemodynamic disorders and can be used to track high-risk stroke cases early in ICA or MCA occlusion, as a simple imaging method.

Acute Effects of Inorganic Nitrate Intake on Brachial and Femoral Flow-Mediated Vasodilation, and on Carotid Artery Reactivity Responses: Results of a Randomized, Double-Blinded, Placebo-Controlled Cross-Over Study in Abdominally Obese Men

Most studies on the effects of inorganic nitrate intake have concentrated on one particular aspect of the endothelial cell response to a stimulus, possibly missing other important outcomes. Participants were given a drink containing 10 mmol potassium nitrate or an iso-molar placebo drink with potassium chloride in a random order. Following nitrate intake, the arterial nitrate plus nitrite concentration in circulating risen at 4 h. In conclusion, this trial did not provide evidence for the effects of a single dose of inorganic nitrate on abdominally obese men's 4 h vascular endothelial function.

Internal carotid artery dissection following self-manipulation: A case report

Symptoms of cervical artery dissection include pain, Horner syndrome, cranial and cervical neuropathies, and pulsatile tinnitus. We review the case of a traumatic internal carotid artery dissection in a healthy 26-year-old female after self-manipulation of the neck. Though the appearance of a patient with neurologic sequelae from a cervical artery dissection causing stroke is a well-known condition, the underlying cause in this particular case is unusual. Several case reports in the literature relating cervical artery dissections by educated professionals following cervical manipulative therapy, but none arising from self-manipulation of the neck. Following self-manipulation with appropriate medical therapy, this case report describes the positive outcomes of a rare case of internal carotid dissection.

Detection of Carotid Artery Stenosis Based on Video Motion Analysis for Fast Screening

Background Carotid artery stenosis is a common cause of ischemic stroke, and early detection of CAS could improve patient outcomes. This article discusses a novel noninvasive and noncontact detection technique used video u2010 motion analysis to extract useful information from subtle pulses on the skin surface to screen for CAS. Methods and Results We prospectively enrolled 202 patients with Doppler ultrasound findings from prior carotid Doppler ultrasound studies. A short 30 second video clip of the neck was taken using a commercial cell phone and analyzed by VMA with numerical quantification of skin movement changes in a blinded manner. The area under the curve of VMAu2010derived discrepancy values to distinguish patients with and without CAS was excellent, judging patients with and without CAS was also noteworthy. Conclusions A simple and fast screening procedure to quickly screen for CAS using a VMA device is cost effective, with acceptable sensitivity and specificity.

Does Current Evidence Support Carotid Artery Stenting for Asymptomatic Patients?

Interventions by Carotid interventions, carotid endarterectomy, and carotid artery stenting have all been proven to be safe treatments for the prevention of ischaemic stroke in newly symptomatic patients. In the absence of new signs referring to the carotid disease, reviewed the literature shows that carotid artery stenosis of any degree is a relatively poor predictor of ipsilateral stroke.

Carotid Artery Stenosis

Stroke is one of the world's most common causes of death, and carotid artery stenosis is a frequent cause of ischaemic strokes. Symptomatic patients are often treated with either carotid endarterectomy or carotid artery stenting. Patients with Asymptomatic disease can be treated with the best medical care, CEA, or CAS.

RAPID Tmax map was useful for determining the site of acute right internal carotid artery occlusion presenting with cerebral infarction in the right posterior cerebral artery region

Background: A relative cerebral blood flow of 6 s is determined as the penumbra in computed tomography perfusion using rapid processing of perfusion and diffusion, and the perfusion mismatch is estimated. Based on RAPID analysis based on CT perfusion analysis, we discuss the case of a patient with right posterior cerebral artery occlusion based on RAPID analysis. With a fetal-type PCA. Case Report, a 94-year-old woman arrived at our hospital in unconscious state and was immediately referred to emergency medical assistance. The right PCA and right ICA occlusion were discovered, with blood supply to the right middle cerebral artery demonstrating cross-flow via the anterior communicating artery. The right MCA had a Tmax of > 4 s on the Tmax chart, showing a blood flow disruption in the right MCA.

Patient-Tailored Stenting versus Endarterectomy for the Treatment of Asymptomatic Carotid Artery Stenosis

Given the repercussions and sequelae of an acute ischemic stroke, an intervention when patients are still asymptomatic is a significant route to stroke prevention. Although carotid stenosis therapy has long been the gold standard of care for carotid stenosis, new advancements in carotid stenting techniques, practitioner training, and dual antiplatelet therapy have expanded the use for treatments other than endarterectomy. Endarterectomy and carotid artery stenting produce overall similar results for the treatment of asymptomatic carotid stenosis, according to a systematic review of the current literature, but certain conditions can aid physicians and patients in choosing one therapy over the other in determining one procedure over the others.

Contribution of UltraFastâ„¢ Ultrasound and Shear Wave Elastography in the Imaging of Carotid Artery Disease

Carotid artery disease is one of the leading global causes of disability and premature death in the spectrum of cardiovascular diseases. Shear wave elastography, another newly developed ultrasound technique, is based on the visualization of induced shear waves and the determination of the shear wave propagation speed in the examined tissues, which allows real-time carotid plaque and wall analysis. These recently developed ultrasound systems have the ability to dramatically boost workflow efficiency while also delivering a slew of additional imaging evidence of carotid artery disease in comparison to traditional ultrasound procedures.

Computed Tomography Texture Analysis of Carotid Plaque as Predictor of Unfavorable Outcome after Carotid Artery Stenting: A Preliminary Study

We therefore tried to determine the relationship between textural characteristics of carotid plaque at computed tomography angiography and unfavorable results after carotid artery stenting. 172 patients who underwent CAS with CTA of the supra-aortic vessels within the first 6 months were selected between January 2010 and January 2021. The predictive model for unfavorable outcome using CTA textural elements outperformed the model without textural information. Histogram analysis, which was derived from CTA density histogram analysis, is an independent predictor of adverse outcomes following CAS in patients with stenotic carotid plaque.
