D-Dimer Levels And Acute Pulmonary Embolism Development In Covid-19 Patients, Vural Ahmet, Kahraman Ahmet Nedim

Journal of Mind and Medical Sciences

Objective. To identify those who develop pulmonary embolism with Ddimer levels by evaluating pulmonary CT angiographies of patients who are followed up with suspicion of coronavirus disease 2019 (COVID-19). Methods. Patients who were followed up in a community hospital with suspicion of COVID-19 and underwent Pulmonary CT angiography examination were evaluated. Clinical and demographic parameters and DDimer values for patients with and without pulmonary embolism were evaluated in the pulmonary CT angiogram. Results. During the COVID-19 pandemic, Thorax CT examination was performed in our center for suspicion or follow-up of COVID-19 infection in 3396 patients. Pulmonary CT angiography was applied …

The Effect Of Sepsis On Cerebral Microvascular Blood Flow, Laura Mawdsley, Mamadou Diop, Chris G. Ellis

Western Research Forum

Background: Sepsis is a dysregulated host response to infection that affects 18 000 000 people worldwide, and over 325 000 000 dollars are spent treating sepsis in Canada every year. One of the symptoms of severe sepsis is an altered mental state, which is accompanied with a measured decrease in oxygen levels in the skeletal muscle microvasculature. It is hypothesized that his altered mental state is due to a lack of oxygenated blood reaching the brain.

Hypothesis: After the onset of sepsis, microvascular cerebral blood flow and oxygen levels in the blood will decrease. Onset of decreased blood flow in …

Transcranial Sonothrombolysis Using High-Intensity Focused Ultrasound: Impact Of Increasing Output Power On Clot Fragmentation, Golnaz Ahadi, Christian S. Welch, Michele J. Grimm, David J. Fisher, Eyal Zadicario, Karin Ernström, Arne H. Voie, Thilo Hölscher

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

The primary goal of this study was to investigate the relationship between increasing output power levels and clot fragmentation during high-intensity focused ultrasound (HIFU)-induced thrombolysis.

Methods

A HIFU headsystem, designed for brain applications in humans, was used for this project. A human calvarium was mounted inside the water-filled hemispheric transducer. Artificial thrombi were placed inside the skull and located at the natural focus point of the transducer. Clots were exposed to a range of acoustic output power levels from 0 to 400 W. The other HIFU operating parameters remained constant. To assess clot fragmentation, three filters of different …

Effects Of Arterial Strain And Stress In The Prediction Of Restenosis Risk: Computer Modeling Of Stent Trials, Shijia Zhao, Linxia Gu, Stacey R. Froemming

Department of Mechanical and Materials Engineering: Faculty Publications

Purpose — In-stenting restenosis is one of the major complications after stenting. Clinical trials of various stent designs have reported different restenosis rates. However, quantitative correlation between stent features and restenosis statistics is scant. In this work, it is hypothesized that stress concentrations on arterial wall caused artery injury, which initiates restenosis. The goal is to assess the correlation between stent-induced arterial stress and strain and the documented restenosis rates.

Methods — Six commercially available stents, including balloon-expandable stents and self-expanding stents, were virtually implanted into the arteries through finite element method. The resulted peak Von Mises stress, principal stress, …

Postmortem Demonstration Of The Source Of Pulmonary Thromboembolism: The Importance Of The Autopsy, Gina Elhammady, Andrew T. Schubeck, Vicky El-Najjar, Morton J. Robinson

HWCOM Faculty Publications

Periprostatic or paravaginal venous thromboses are rarely considered clinically as sites of clot origin in patients with pulmonary thromboembolism. The majority of emboli have been demonstrated to originate in the veins of the legs. This report raises awareness of pelvic vein thrombosis as a potential source of pulmonary embolism that is rarely considered or detected clinically, and which usually requires postmortem examination for recognition. It also reviews the possible routes emboli may take to reach the lungs.
