“…The speci city and sensitivity of diagnosis by ASL meet clinical requirements, and its application in patients with carotid atherosclerosis is expanding [12,13]. Previous studies have pointed out that for the changes of overall perfusion after CEA [6]. After checking the perfusion of different parts, we found that some corrections were needed for the time of prediction.…”

“…In particular, postoperative hyperperfusion syndrome has attracted increasing attention from clinicians due to the di culty in its prediction and its serious consequences [4,5]. Therefore, monitoring the time and severity of postoperative hyperperfusion is of signi cance for both objective analysis of surgical e cacy and to prevent postoperative hyperperfusion syndrome [6][7][8].…”

Background:Carotid endarterectomy (CEA) is an effective method for treating cerebral ischemia caused by carotid stenosis, but there may be a risk of perfusion pressure breakthrough during early perfusion recovery. As a non-invasive and contrast-free magnetic resonance examination method, arterial spin labeling can be used for continuous observation and measurement in the early postoperative period of carotid endarterectomy. Results: Nineteen patients with severe unilateral carotid stenosis were examined using 3D pseudo-continuous arterial spin labeling before and after CEA, and we found that the pattern of dynamic cerebral blood flow changes is not the same in different regions.Conclusions: 3D pseudo-continuous arterial spin labeling might be helpful for the improvement of postoperative treatment and care of severe unilateral carotid stenosis patients.

“…ECAS refers to the presence of atherosclerotic narrowing of the common carotid artery, carotid bifurcation, or extracranial internal carotid 3 . Duplex sonography is a widely used, noninvasive, easily performed, and cost-effective initial diagnostic imaging method with high sensitivity and specificity in ECAS evaluation 4 , 6 , 36 .…”

The cardiovascular health (CVH) metrics are closely related to the risk of stroke. Extracranial carotid artery stenosis (ECAS) represents an important risk factor for ischemic stroke. The present study aims to explore the longitudinal effect of the baseline CVH metrics on the development of ECAS. Totally 5,440 participants were randomly enrolled in the Asymptomatic Polyvascular Abnormalities Community study from 2010 to 2011. Information regarding the seven CVH metrics was collected at baseline. ECAS was assessed by performing carotid duplex sonography at baseline (2010–2011) and during the follow-up (2012–2013). Finally 3,487 subjects were included, and 976 participants developed ECAS during the 2-year follow-up. The optimum CVH status was associated with a 42% (95% confidence interval: 0.40–0.85) decreased risk of the incidence of ECAS after adjusting for age, sex, weight, education, income, alcohol use, waist-hip ratio, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, uric acid, homocysteine, and C-reactive protein. Ideal physical activity, total cholesterol and fasting blood glucose were independent protective factors of ECAS. In this cohort study, the ideal baseline CVH status was negatively associated with the occurrence of ECAS during the follow-up. This study provides practical insight for further developing effective screening strategies or implementing the best medical treatment.

“…Their outcomes revealed that B-Mode method shows sufficient accuracy and precision to determine morphological and physiological properties of arterial wall in symptomatic patients but wave form details may be invisible in this approach and cannot be used for advanced proposes. Pandya and Gupta [10] suggested that using duplex US studies at first step and then using angiography (as second-line exam) can be helpful to reduce the number of false-positive CAS findings. They mentioned that risk of angiography is relatively high and could be replaced by other invasive test such CT angiography or MR angiography.…”

“…CAD can be classified in two subgroups: 1) symptomatic and 2) asymptomatic. Most of CAD patients have not obvious symptoms and asymptomatic CA is accounted as a public health issue [10] and usually after formation of mild and sever stenosis (50% and above) symptoms can be observed. Therefore, researchers are keen to understand CAD mechanisms before CAD turns to symptomatic goes to critical stages.…”

Cardiovascular diseases take many lives yearly and carotid atherosclerosis disease is responsible of a significant portion of cardiovascular deaths. Carotid atherosclerosis disease is a multi-aspects disease and only by considering all of its aspects, a comprehensive insight can be achieved whereas near all of researchers which have been conducted to study, cover only one or two aspects of carotid atherosclerosis disease. Current review by summarizing and categorizing of 77 selected literatures which were published in different scopes of carotid atherosclerosis disease, have attempted to present a comprehensive and succinct source for further studies and fill the gap between carotid atherosclerosis disease aspect by presenting them coincidently. In this review, usage of common diagnostic methods such as ultrasonography and magnetic resonance imaging in carotid atherosclerosis disease detection have been discussed. Also, Current review shows that carotid atherosclerosis disease is product of combination of biochemical, biomechanical, diseases and human health-related risk factors. Also, high concentration of low density lipoprotein seems to be carotid atherosclerosis disease trigger. In addition, carotid atherosclerosis disease simulations indicate that regions which are prone to carotid atherosclerosis disease are associated with low and oscillatory wall shear stress and recirculation zone. It appears that collaboration of different scopes of carotid atherosclerosis disease can lead to outstanding results and using realistic data in carotid atherosclerosis disease studies leads to more accurate results.
