Management of Acute Ischemic Stroke-Specific Focus on Anesthetic Management for Mechanical Thrombectomy.
Abstract Acute ischemic stroke is a neurological emergency with a high likelihood of morbidity, mortality, and long-term disability. Modern stroke care involves multidisciplinary management by neurologists, radiologists, neurosurgeons, and anesthesiologists. Current American Heart Association/American Stroke Association (AHA/ASA) guidelines recommend thrombolytic therapy with intravenous (IV) alteplase within the first 3-4.5 hours of initial stroke symptoms and endovascular mechanical thrombectomy within the first 16-24 hours depending on specific inclusion criteria. The anesthesia and critical care provider may b...

Acute Ischemic Stroke as a Result of Paradoxical Embolus in a Patient with Renal Cell Carcinoma, Intravenous Tumor Thrombus Extension, and Patent Foramen Ovale
Conclusions: This is the first reported case of intraoperative paradoxical embolism in the setting of RCC with cavoatrial extension and PFO. The presence of PFO may be a risk factor for severe cerebrovascular complications in the surgical management of RCC with venous involvement.

Investigating the Mechanical Behavior of Clot Analogues Through Experimental and Computational Analysis.
Abstract With mechanical thrombectomy emerging as the new standard of care for stroke treatment, clot analogues provide an extremely useful tool in the testing and design of these treatment devices. The aim of this study is to characterise the mechanical behavior of thrombus analogues as a function of composition. Platelet-contracted clot analogues were prepared from blood mixtures of various hematocrits. Mechanical testing was performed whereby clots were subjected to unconfined compression between two rigid plates. Two loading protocols were imposed: cyclic compression for 10 cycles at a constant strain-rate mag...

COVID-19 and Stroke: Casual or Causal Role?
We present a case of stroke in a 62-year-old COVID-19-positive patient, with multiple vascular risk factors. The patient arrived 1 h after onset of symptoms, was treated with recombinant tissue plasminogen activator (rtPA) with improvement of neurologic deficits, and later developed right foot arterial ischemia (recanalized by balloon catheter angioplasty) and left arm superficial venous thrombosis. A control computed tomography (CT) scan 7 days after onset showed hemorrhagic transformation of ischemic lesion without mass effect. However, respiratory and neurologic conditions improved so that the patient was discharged to ...

PET Detection of Cerebral Necrosis Using an Infarct-Avid Agent 2-Deoxy-2- 18 FFluoro- d -Glucaric Acid (FGA) in a Mouse Model of the Brain Stroke
ConclusionsAccumulation of FGA correlated well with the perfusion defect and inflammatory injury. As a PET agent, FGA has potential to image infarcted core in the brain stroke injury with high sensitivity, resolution, and specificity.

Role of pericyte-derived SENP1 in neuronal injury after brain ischemia.
CONCLUSIONS: Our findings revealed that targeting SENP1 in pericytes may represent a novel therapeutic strategy for neurovascular protection in stroke. PMID: 32495523 [PubMed - as supplied by publisher]

Acute ischemic stroke management in Lebanon: obstacles and solutions.
This study assesses the current practices of physicians in Lebanon routinely involved in ischemic stroke (IS) management. We conducted a prospective observational study of patients hospitalized at 8 different Lebanese hospitals in the period August 1, 2015 to July 31, 2016, with a diagnosis of acute stroke. Baseline characteristics and data on diagnostic studies, as well as treatments received during hospitalization and at discharge, were collected and analyzed. Two hundred and three strokes/transient ischemic attacks (TIAs) were recorded but only 173 patients (85%) with ischemic events were included in the study. The pati...

The management of patients with acute ischemic stroke while on direct oral anticoagulants (DOACs): data from an Italian cohort and a proposed algorithm
This study aimed at investigating whether there is any relationship between DOAC plasma levels and the stroke occurrence, on the basis of the phenotypic classification and pathophysiology of the stroke, in a cohort of DOAC-treated patients admitted to our hospital for AIS o ver 1-year period. A total of 28 patients had DOAC plasma levels determined in emergency and were included in the study, nine patients receiving dabigatran, 11 rivaroxaban and 8 apixaban. The DOAC levels were low in 8/28 patients (28.6% of the sample), intermediate in 4 (14.3%) and high in 16 (57.1% ). The most prevalent stroke subtype was the small ves...

Outcome of patients receiving a continuous flow left ventricular assist device - a retrospective single center study.
Conclusions. Survival rates were good, although one third of patients were bridged with temporary circulatory support. We report a high level of freedom from pump thrombosis, fatal stroke, and driveline infection. PMID: 32292078 [PubMed - as supplied by publisher]

Sinus of Valsalva Thrombosis Detected on Computed Tomography after Transcatheter Aortic Valve Replacement.
CONCLUSIONS: Cardiac CT after TAVR can detect sinus of Valsalva thrombosis, and attention should be paid to this potential source of subsequent systemic embolization. PMID: 32281322 [PubMed - as supplied by publisher]

A Case of Ischemic Stroke With Congenital Protein C Deficiency and Carotid Web Successfully Treated by Anticoagulant and Carotid Stenting
Conclusion: To our knowledge, this is the first report in which an immediate thrombus formation on the carotid web was observed in a patient with congenital protein C deficiency. In a case of acute ischemic stroke with carotid web, especially when congenital coagulopathy such as protein C deficiency is suspected, careful follow-up with ultrasound imaging should be performed.

Symptomatic Carotid Plaques Show Decreased (18)F-Fluorodeoxyglucose (FDG) Uptake on Positron Emission Tomography (PET) After 3 Months Follow-up from Last Symptom
Introduction: The risk of stroke is high shortly after the index symptoms in patients with carotid disease. This indicates that unstable carotid plaques stabilizes over time, which may be due to changes in composition and inflammatory activity. Inflammation is thought to be one of the leading causes in atherosclerotic plaques destabilizing leading to thrombosis. With positron emission tomography (PET) previous studies have shown increased uptake of the glucose analogue tracer [18F]-fluorodeoxyglucose (FDG) in symptomatic compared to asymptomatic carotid plaques.
