Anatomy of the celiac trunk examined by CT imaging of 104 individuals.

The diameter, length and emergence level of the celiac trunk is measured with CT angiography in 104 patients who have no shown abnormality in the abdomen. The celiac trunk emerged at T 12 level in 79.8%, at L 1 level in 14.4% and at T 11 level in 3.8% of the patients. The mean length of the celiac artery was 6.69 +/- 1.22 mm in the females and 7.13 +/- 1.18 in the males. The mean diameter of the celiac artery was 2.87 +/- 0.52 cm in the males and 2.75 +/- 0.59 in the females. There was no correlation between the diameter and the length. The values are in accordance with cadaveric studies and can be used as criteria for diagnosis of celiac narrowing and aneurysms.
