Indications for and experience with placement of endovascular stent-grafts in the thoracic aorta are still evolving. Common pathologic conditions of the thoracic aorta that are amenable to stent placement include penetrating ulcers, aortic dissection, aortic aneurysms, aortic rupture, and congenital abnormalities. Advances in multidetector computed tomography (CT) permit high-quality two-dimens...

ACCORDING to Christie and Dahl 1 the abdominal portion of the rat aorta shows a significantly lower respiration than its thoracic segment. The divergence increases with, aging. Briggs, Chernick and Chaikoff,in an earlier study, did not detect this phenomenon. The first authors suggest that the preferential sites of development of atherosclerotic lesions might show a lower rate of respiration. T...

Descending thoracic aorta to femoral bypass graft is an alternative procedure for revascularization of the lower extremities to conventional techniques, when the abdominal aorta is complete obstructed. In general, this technique is performed by surgeons, when abdomen is unable to be opened due to the presence of an abdominal infection, fistulas, or hostile abdomen. In this article, we present o...

Aortic aneurysms usually develop in the atherosclerosis prone infrarenal abdominal aorta. To assess the role of atherosclerosis in aortic enlargement, we studied the relation between plaque formation and aortic size in 30 pressure-fixed male cadaver aortas (age 40-95 years, mean age 67 years). Morphometric analysis of transverse sections of the mid-thoracic and the mid-abdominal aortas included...
