    Role of molecular imaging with positron emission tomographic in aortic aneurysms.
    J Thorac Dis 2017 Apr;9(Suppl 4):S333-S342
    Department of Cardiology, Weill Cornell Medicine, New York, USA.
    Aortic aneurysms (AA) are often asymptomatic before the occurrence of acute, potentially fatal complications including dissection and/or rupture. Beyond aortic size, the ability to assess aortic wall characteristics and processes contributing to aneurysm development may allow improved selection of patients who may benefit from prophylactic surgical intervention. Current risk stratification for aneurysms relies upon routine noninvasive imaging of aortic size without assessing the underlying pathophysiologic processes, including features such as inflammation, which may be associated with aneurysm development and progression.

    Oesophageal fistulae after thoracic endovascular aneurysm repair (TEVAR) for thoracic aortic aneurysm (TAA) have been reported, although the causes are unknown. One hypothesis is that the structural configuration of the aortic aneurysm, as it protrudes towards the oesophagus, may affect oesophageal fistula formation. The pathological findings of an oesophageal fistula following TEVAR are reviewed here. Read More

    Aneurysms of the thoracic and abdominal aorta are common and can be associated with significant morbidity and mortality when complications, including dissection, rupture, or thrombosis, occur. Current approaches to diagnosis and risk stratification rely on measurements of aneurysm size and rate of growth, often using various imaging modalities, which may be suboptimal in identifying patients at the highest and lowest risk of complications. Targeting the biological processes underlying aneurysm formation and expansion with molecular imaging offers an exciting opportunity to characterize aortic aneurysms beyond size and address current gaps in our approach to diagnosis and treatment.
