Lack of Association between Carotid Artery Stenosis and Stroke or Myocardial Injury after Noncardiac Surgery in High-risk Patients
Conclusions: This cohort represents a high-risk population, as carotid duplex examinations were likely prompted by neurological symptoms. There was nonetheless no association between carotid artery stenosis and perioperative stroke or 30-day mortality after noncardiac surgery.

Intraoperative epiaortic scanning for preventing early stroke after off-pump coronary artery bypass
Conclusions EAS has a significant clinical benefit in reducing the incidence of early stroke in cases of partial aortic clamping in OPCAB. Therefore, EAS should be considered in patients who need partial aortic clamping in OPCAB.

A Case-Based Discussion on the Management of Cryptogenic Stroke and Patent Foramen Ovale in the Patient With a Hypercoagulable Disorder
UP TO 40% of all ischemic strokes are considered cryptogenic, implying a stroke without a definitive etiology.1,2 With a dearth of evidence-guided treatment strategies, the literature surrounding cryptogenic stroke is highly variable and not well-standardized. Even though existing guidelines do not specify the exact testing required, the cryptogenic stroke evaluation includes a variety of imaging modalities (eg, echocardiography, angiography, magnetic resonance imaging, carotid ultrasound) and laboratory investigations (eg, genetic testing, hypercoagulable disorder panels, erythrocyte sedimentation rate).

Stroke Volume Monitoring: Novel Continuous Wave Doppler Parameters, Algorithms and Advanced Noninvasive Haemodynamic Concepts
AbstractPurpose of ReviewAdequate oxygen delivery is essential for life, with hypoxia resulting in dysfunction, and ultimately death, of the cells, organs and organism. Blood flow delivers the oxygen bound in the blood, while haemodynamics is the science of blood flow. Stroke volume (SV) is the fundamental unit of blood flow, and reflects the interdependent performance of the heart, the vessels and the autonomic nervous system. However, haemodynamic management remains generally poor and predominantly guided by simple blood pressure observations alone.Recent FindingsDoppler ultrasound measures SV with unequalled clinical pr...

Evaluation of the risk factors for neurological and neurocognitive impairment after selective cerebral perfusion in thoracic aortic surgery
ConclusionsWe found that prolonged SCP time and coronary artery disease increased the risk of postoperative stroke. Heterogeneous carotid plaque, history of cerebrovascular disease, concomitant CABG and prolonged operation time were further significant predictors of POCD.

Predicting fluid responsiveness in children: a systematic review.
CONCLUSIONS: Respiratory variation in aortic blood flow peak velocity was the only variable shown to predict fluid responsiveness in children. Static variables did not predict fluid responsiveness in children, which was consistent with evidence in adults. Dynamic variables based on arterial blood pressure did not predict fluid responsiveness in children, but the evidence for dynamic variables based on plethysmography was inconclusive.

Changes in blood volume indicators and dynamic indicators measured with transpulmonary ultrasound velocity during blood depletion and repletion in a neonatal swine model
ConclusionTotal end‐diastolic volume and central blood volume changed during blood depletion and repletion, and differed between stages of hemorrhage. These indicators might be useful for assessing volume status instead of, or in addition to cardiac index and dynamic indicators.

The Clinical Features of Dissection of the Cervical Brain-Supplying Arteries
CONCLUSION: Dissection of the cervical brain-supplying vessels is not always revealed by the imaging methods that are used to detect it. Stroke prevention thus depends on the physician's being aware of the symptoms and signs of this disease entity, so that early diagnosis can be followed by appropriate treatment.PMID:35734920 | DOI:10.3238/arztebl.m2022.0238

Respiratory Variation of Internal Carotid Artery Blood Flow Peak Velocity Measured by Transfontanelle Ultrasound to Predict Fluid Responsiveness in Infants A Prospective Observational Study
Conclusions The respiratory variation of the internal carotid artery blood flow peak velocity as measured using transfontanelle ultrasound predicted an increase in stroke volume in response to fluid. Further research is required to establish any wider generalizability of the results.

Safety and efficiency of ultrasound-guided intermediate cervical plexus block for carotid surgery
Conclusions The present work reports our first 50 cases of intermediate CPB using ultrasound guidance. The results underline that this technique is easy to perform, safe and reliable, provided good surgical conditions with continuous intraoperative neurologic monitoring and stable haemodynamics are respected.

Meta-analyses on measurement precision of non-invasive hemodynamic monitoring technologies in adults.
Abstract An ideal non-invasive monitoring system should provide accurate and reproducible measurements of clinically relevant variables that enables clinicians to guide therapy accordingly. The monitor should be rapid, easy to use, readily available at the bedside, operator-independent, cost-effective and should have a minimal risk and side effect profile for patients. An example is the introduction of pulse oximetry, which has become established for non-invasive monitoring of oxygenation worldwide. A corresponding non-invasive monitoring of hemodynamics and perfusion could optimize the anesthesiological treatment...

Functional Hemodynamic Monitoring with a Wireless Ultrasound Patch
In this Emerging Technology Review a novel, wireless, wearable Doppler ultrasound patch is described as a tool for resuscitation. The device is designed, foremost, as a functional hemodynamic monitor – a simple, fast and consistent method for measuring hemodynamic change with preload variation. More generally, functional hemodynamic monitoring is a paradigm that helps predict stroke volume response to additional intravenous volume. Because Doppler ultrasound of the left ventricular outflow tra ct non-invasively measures stroke volume in real-time, it is increasingly deployed for this purpose.

The response of internal carotid artery blood flow velocity to fluid challenge under general anesthesia in pediatric patients with moyamoya disease: a prospective observational study
CONCLUSIONS: The internal carotid artery blood flow velocity did not increase in pediatric patients with moyamoya disease under general anesthesia, despite fluid challenge and corresponding changes in the blood pressure and cardiac output. Intraoperative hemodynamic management to improve the cerebral blood flow in these patients requires further investigation.PMID:36164813 | DOI:10.1111/pan.14558

A Woman With a History of Stroke and a Mass in the Aorta
A 65-YEAR-OLD WOMAN presented with an acute onset of slurred speech and left facial droop. She had a past medical history of Raynaud's disease, well-controlled hypertension, and moderate tricuspid regurgitation, which was being followed by serial transthoracic echocardiographic examinations. A duplex ultrasound of the carotid and vertebral arteries was negative, whereas a magnetic resonance imaging scan of her brain revealed a subacute embolic cerebral infarction. A transesophageal echocardiographic (TEE) examination also was performed during the workup, revealing the presence of moderate-to-severe tricuspid regurgitation ...
