Rare observation of the aortic arch in a young woman with a favorable morphotype suprasternal approach. The origin of the supra-aortic trunks arrows and the right pulmonary artery PẤ in transverse section are exposed in detail Fig. . Terminal aorta sequel of Figs. and . Arrows origin of the iliac arteries. This type of image can replace more invasive modalities such as CT or angiography in emergency situations Fig. . The descending thoracic aorta is exposed over 12 cm in this scan that exploits the cardiac window apical scan of the heart Fig. . Thoracic aorta aneurysm. Suprasternal scan in a patient in shock with thoracic pain. Note the substantial thrombosis with regular layers. A circulating lumen of the aorta back to the periphery a few millimeters in each systole. In the case of thoracic aortic dissection Fig. an enlarged lumen of the aorta can be observed and in some cases the intimal flap. This flap has an anatomical shape . never completely regular and in our opinion is easily distinguished from the numerous artifacts that are always too regular and generally located in a strictly parallel or meridian plane. However the search can be difficult depending on the morphotype the situation of the flap with respect to the probe axis and probably also the operator s experience here. The supra-aortic vessels can be followed to various lengths but the application seems rare at least in medical ICU use see Chap. 21 .
