Both contours displayed similar flow patterns in the regions of interest--aortic arch, aortic branches, and
descending aorta. There are slight discontinuities near the aortic root region; however, due to the primary interest of flows downstream, this difference can be ignored.
Representative SPECT/CT 3D reconstructions show longitudinal 3-hour [sup.111]In-DANBIRT SPECT/CT scans, which allowed us to identify atherosclerosis-prone ROI established in the aortic arch and the initial portion of the
descending aorta tissues shown in the representative images displayed with the ROI volumes in red color that are being pointed by the red arrows (Figure 4(a)).

descending aorta.
To the best of our knowledge, the present case is the first to illustrate an acute occlusion of the
descending aorta in a patient after out-of-hospital cardiac arrest.

There is also an extremely rare left aortic arch with a right
descending aorta and a right ductus arteriosus where a Kommerell's diverticulum has been described.
Last year docs replaced two-thirds of my
descending aorta - the final part will be replaced in a few years' time.

In the computed tomography (CT) and CT angiography, aortic dissection extending from the thoracic level in the
descending aorta to the iliac artery was observed (Figure 1).
On the other hand, in the DeBakey classification, type 1 dissections begin in the ascending aorta and extend to the descending one, while type 2 dissections involve the ascending aorta only and type 3 dissections begin in the
descending aorta distal to the left subclavian artery (5).
After anesthesia was induced by tribromoethanol (10 mg/kg of body weight), a left laparotomy was performed, the
descending aorta was isolated and a bent 21-gauge needle was placed next to the aorta.
