Balloon was selected according to transverse arch diameter but not exceeding descending aorta
diameter at level of diaphragm.
Crawford classification of thoracoabdominal aortic aneurysm Type I From distal to the left subclavian artery to above the renal arteries Type II From distal to the left subclavian artery to below the renal arteries Type III From the midthoracic descending aorta
to below the renal arteries Type IV From the diaphragm to below the renal arteries Type V From the sixth intercostal space to above the renal arteries Table 2.

The descending aorta
is very near to the left atrium.
Once the fluid resistance-nozzle angle relationship was defined, effective fluid resistances were applied at the branching arteries and descending aorta
to perform the time-variable simulations of blood and water glycerol.
Collateral flow can be assessed by quantifying flow just proximal to the coarctation and in the descending aorta
at the level of the hiatus.
There was evidence of a Grade 5 (mobile or ulcerating) atheroma in the transverse aorta, with a visualized plaque in the descending aorta
. There was also evidence of a Grade 4 (>5 mm) atheroma in the descending aorta
The ROIs were extrapolated from the reconstructed CT image and adjusted according to specific morphologic parameters for each mouse tissue such as the aortic arch, descending aorta
, and muscle.
In 2013, she underwent coronary artery bypass graft (CABG) surgery with an IMA bypass to the left anterior descending (LAD) and implantation of an aortic valve bioprothesis in extraanatomic position with a conduit from the apex of the left ventricle to the descending aorta
for treatment of a symptomatic aortic valve stenosis.
Main findings were as follows: a large ventricular septal rupture with classical radiological signs of acute myocardial infarction (Figure 1), signs of severe backward failure with contrast agent being observed in hepatic veins, renal veins (Figure 1), the portal vein and the inferior vena cava (Figure 1), and thrombotic occlusion of the descending aorta
just distal to the left subclavian artery (Figure 2).
Chest X-ray showed an inhomogeneous opacity in the left lower zone with raised left diaphragm (Figure 1), and CECT (contrast-enhanced computer tomogram) chest showed a hypodense lesion with irregular margins in the anterior segment of the left lower lobe adjacent to the descending aorta
and associated subcarinal lymphadenopathy (Figures 2 and 3).
The prognosis of AEF is poor because of rerupturing and/or the development of infections; therefore, esophageal resection with or without esophageal reconstruction, as well as replacement of the descending aorta
, should be planned after TEVAR for AEF.
It is missed due to the presence of a patent ductus arteriosus (PDA) in the first 3 days of life, which maintains blood supply to the descending aorta
from the pulmonary artery .
CT of the chest revealed the aneurysmatic dilatation of the ascending arch and the descending aorta
and pulmonary infiltrates in left upper lobe suspicious of aorto-bronchial fistula with bleeding in the lung (Figures 2, 3, and 4).
