Effective evaluation of arterial pulse waveform analysis by two-dimensional stroke volume variation –stroke volume index plots
In this study, we analyzed how we visually interpret hemodynamic data, including stroke volume variation (SVV) and stroke volume (SV) derived from APWA. We performed arithmetic estimation of the SVV –SV relationship and applied measured values to this estimation. We then collected measured values in six anesthesia cases, including three liver transplantations and three other types of surgeries, to apply them to this SVV–SVI (stroke volume variation index) plot. Arithmetic analysis showed th at the relationship between SVV and SV can be drawn as hyperbolic curves. Plotting SVV-SV values in the semi-logarithmic scale sho...

Initial experience with the WATCHMAN ™ left atrial appendage system for stroke prevention in atrial fibrillation: A single-centre registry.
CONCLUSION: When performed by an operator trained in the procedure, WM implantation appears to be safe and effective. This procedure may be considered in patients at high-risk of stroke who are ineligible for long-term OAC. PMID: 27594651 [PubMed - as supplied by publisher]

Intra-arterial Contrasted Cone-beam Computed Tomography Assessment of Vessels Distal from Occluded Site in Acute Ischemic Stroke with Major Vessel Occlusion.
Authors: Amano T, Sato M, Matsumaru Y, Sakuma H, Yoda S, Hamada Y Abstract Characterization of vessels distal from occluded site is important when considering endovascular revascularization therapy (EVT) for acute ischemic stroke. The goal of this study was to assess the clinical value of intra-arterial contrasted high-resolution cone-beam computed tomography from the ascending aorta (Ao-CBCT) for visualization of the vessels distal from occluded site. Acute ischemic stroke patients with large vessel occlusion who were to undergo EVT were evaluated. In EVT, digital subtraction angiography (DSA) and Ao-CBCT were per...

Perioperative Stroke Screening Tool (Phase I)
Within 12-months, two patients exhibited symptoms of stroke that were not recognized in a timely manner in the PACU at UMMC. Incidence of perioperative stroke in non-cardiac, non-neurological surgery patients is approximately 1 per 1000 cases but is associated with an eight fold increase in mortality. Due to confounding factors of anesthesia and frequent opioid administration, stroke symptoms can easily be masked. No screening tool for perioperative stroke in this population was found in the literature.

Assessing the efficacy of endovascular therapy in stroke treatments: updates from the new generation of trials.
Authors: Walker GB, Jadhav AP, Jovin TG Abstract INTRODUCTION: For the past 20 years, intravenous recombinant tissue plasminogen activator (rt-PA) has been the only proven treatment for acute ischemic stroke. Large arteries such as the internal carotid artery, the middle cerebral artery and the basilar artery supply blood to large volumes of brain tissue. When occluded, these vessels may have low response rates to rt-PA resulting in devastating injury and death. . Areas Covered: In 2013, three trials evaluating the efficacy of mechanical thrombectomy in acute stroke were neutral, however, lessons learned from these...

Carotid Artery Disease as a Predictor of In-Hospital Postoperative Stroke After Coronary Artery Bypass Grafting From 1999 to 2011
In this study, the risk factors for stroke after coronary artery bypass grafting (CABG) were examined. In particular, the role of asymptomatic carotid artery stenosis (both unilateral and bilateral) as a predictor of in-hospital postoperative stroke was investigated. Finally, the trends surrounding in-hospital postoperative stroke from 1999 to 2011 also were examined. The purpose of the study was to appropriately identify patients at high risk for stroke after CABG and spark discussion about the perioperative management of such patients.

Refinement of embolic stroke model in rats: effect of post-embolization anesthesia duration on arterial blood pressure, cerebral edema and mortality
Conclusions These data indicate that early discontinuation of isoflurane anesthesia after clot embolization permits an earlier hypertensive response that limits edema formation and mortality without significantly affecting infarct volume in survivors, thereby decreasing the required number of animals.

Effects of Temporary Functional Deafferentation in Chronic Stroke Patients: Who Profits More?
Abstract Temporary functional deafferentation (TFD) by an anesthetic cream on the stroke-affected forearm was shown to improve sensorimotor abilities of stroke patients. The present study investigated different predictors for sensorimotor improvements during TFD and indicated outcome differences between patients grouped in subcortical lesions only and lesions with any cortical involvement. Thirty-four chronic stroke patients were temporarily deafferented on the more affected forearm by an anesthetic cream. Somatosensory performance was assessed using von Frey Hair and grating orientation task; motor performance wa...

Neuroprotective Action of Human Wharton's Jelly-Derived Mesenchymal Stromal Cell Transplants in a Rodent Model of Stroke.
Abstract Wharton's jelly-derived mesenchymal stromal cells (WJ-MSCs) have distinct immunomodulatory and protective effects against kidney, liver, or heart injury. Limited studies have shown that WJ-MSCs attenuates oxygen-glucose deprivation-mediated inflammation in hippocampal slices. The neuroprotective effect of intracerebral WJ-MSC transplantation against stroke has not been well characterized. The purpose of this study was to examine the neuroprotective effect of human WJ-MSC (hWJ-MSC) transplants in an animal model of stroke. Adult male Sprague-Dawley rats were anesthetized and placed in a stereotaxic frame. ...

Perioperative stroke & #8211; Prediction, Prevention, and Protection
Amarja S NagreIndian Journal of Anaesthesia 2018 62(10):738-742 Stroke culminates into 6.2 million deaths annually and is thereby a leading cause of disability and death worldwide. In patients undergoing noncardiac, nonneurological surgery, perioperative stroke can eventuate into a catastropic aftermath with almost eight-fold rise in mortality. In cardiac, neurological, and carotid surgery, stroke rate accounts to be high (2.2%–5.2%) and is a significant instigator of morbidity and mortality as well. These facts kindle interest to review the predictive parameters, preventive measures, an...
