150px 140px Side views (sagittal plane) of the descending aorta and two of its branches, the celiac trunk and superior mesenteric artery, demonstrate normal and<unk>  anatomy. Left The<unk><unk><unk>  is normally several millimeters to centimeters superior to the origin of the celiac artery. Right In<unk> , the<unk>  is anterior, rather than superior, to the celiac artery, resulting in compression of the vessel and a characteristic hook-shaped contour. The<unk><unk><unk>  is a<unk>  formed at the base of the diaphragm where the left and right diaphragmatic crura join near the 12th thoracic vertebra. This fibrous arch forms the anterior aspect of the aortic hiatus, through which the aorta, thoracic duct, and azygos vein pass. The<unk><unk><unk>  usually comes into contact with the aorta above the branch point of the celiac artery. However, in up to one quarter of normal individuals, the<unk><unk><unk>  passes in front of the celiac artery, compressing the celiac artery and nearby structures such as the celiac ganglia. In some of these individuals, this compression is pathologic and leads to the<unk> .
