Chapter 37 Pathophysiology, Epidemiology, and Prognosis of Aortic Aneurysms Reena L. Pande, Joshua A. Beckman Aortic aneurysms result in significant morbidity and mortality, accounting for nearly 13,000 deaths and 55,000 hospital discharges per year in the United States.1 Although aneurysms may affect any part of the aorta from the aortic root down to the abdominal… Mechanisms of Thrombosis Maureane Hoffman, MD, PhD Professor of Pathology . Localization and activity of tissue factor in human atherosclerotic lesions. Result of Thrombus? However, autopsy studies have identified asymptomatic coronary thrombi on disrupted plaques and pathological differences in plaques with symptomatic and asymptomatic thrombi [1, 2].Therefore, plaque disruption is not a final step, whereas thrombus growth … Thrombus encountered in the setting of acute coronary syndromes has been correlated with acute complications during percutaneous coronary interventions such as no-reflow, acute coronary occlusion and long term complications such as stent thrombus.
