Mycotic Aneurysm Mimicking Atheroma in Aortic Arch
A 51-year-old hemodialysis patient was admitted for methicillin-sensitive Staphylococcus aureus (MSSA) bacteremia from an unknown primary focus. A transthoracic echocardiogram showed no cardiac vegetation. 18 Ffludeoxyglucose positron emission tomography (18F-FDG PET) revealed an increased uptake in the aortic arch (Picture 1, white arrow) with a maximum standard uptake value of 5.30. Both athe...
متن کاملUse of intraoperative epiaortic ultrasonography to delineate aortic atheroma.
OBJECTIVE A cerebrovascular accident (CVA) is a devastating complication of coronary artery bypass grafting (CABG) and a major cause for morbidity and mortality. Aortic manipulation, cannulation, and clamping during CABG may lead to release of atheromatous material from the ascending aorta, which may cause a CVA. This study assessed the hypothesis that the use of intraoperative epiaortic ultras...
متن کاملUltrasonic Imaging
The basic principles of ultrasonic B-mode imaging aresummarized. Tissue features that generate contrast andsystem features that control image quality are reviewed inthe context of breast cancer imaging. Approaches to signalmodeling, including B-mode and Doppler techniques, arereviewed to guide methodological design and clinical eval-uation. The article concludes with a b...
متن کاملIron oxide particles for atheroma imaging.
The selection of patients for vascular interventions has been solely based on luminal stenosis and symptomatology. However, histological data from both the coronary and carotid vasculature suggest that other plaque features such as inflammation may be more important in predicting future thromboembolic events. Ultrasmall superparamagnetic iron oxide (USPIO) contrast agents have been used for non...
متن کاملAortic arch atheroma: stroke reduction in cardiac surgical patients.
Cardiac surgery is increasingly performed on elderly patients with extensive coronary artery abnormalities who have impaired left ventricular function, decreased physiologic reserve, and multiple comorbid conditions. Considerable numbers of these patients develop perioperative neurologic complications ranging from subtle cognitive dysfunction to more evident postoperative confusion, delirium, a...
