Background—The mural thrombus of abdominal aortic aneurysms (AAA) is involved in aneurysm progression via several interdependent biological processes including platelet activation. Tc-annexin V (ANX) is a scintigraphic tracer that binds to phosphatidylserine exposed on activated platelets and apoptotic cells. Here, we evaluated the potential of ANX imaging to assess mural thrombus biological ac...
AIMS Thoracic aortic aneurysm (TAA) is potentially life-threatening and requires close follow-up to prevent aortic dissection. Aortic stiffness and size are considered to be coupled. Regional aortic stiffness in patients with TAA is unknown. We aimed to evaluate coupling between regional pulse wave velocity (PWV), a marker of vascular stiffness, and aortic diameter in TAA patients. METHODS In...
dear editor, abdominal aortic aneurysm is often asymptomatic, less recognized, and causes considerable mortality and morbidity, if missed. the incidence varies from country to country and the occurrence is influenced by modifiable (smoking, coronary heart disease, hypertension, dyslipidemia, and prolonged steroid therapy) and non-modifiable risk factors (increasing age, male gender, and positiv...
An 85-year-old male with stage IV lung cancer, being treated with palliative chemo-radiotherapy for nine months, presented with nausea, early satiety, bilious vomiting, and abdominal pain for 2 weeks prior to admission. During staging, computed tomography revealed an abdominal aortic aneurysm; however, only surveillance was indicated. A month earlier, a self-expandable metallic stent had been p...
OBJECTIVE It is hypothesized that a male predominance, similar to that in humans, persists in a rodent model of experimental abdominal aortic aneurysm (AAA) via alterations in matrix metalloproteinases (MMPs). METHODS AND RESULTS Group I experiments were as follows: elastase perfusion of the infrarenal aorta was performed in male (M) and female (F) rats. At 14 days, aortas were harvested for ...
OBJECTIVE To compare duplex ultrasound and computed tomography (CT) angiography in terms of their performance in detecting endoleaks, as well as in determining the diameter of the aneurysm sac, in the postoperative follow-up of endovascular abdominal aortic aneurysm repair. MATERIALS AND METHODS This was a prospective study involving 30 patients who had undergone endovascular repair of infrar...
