Abstract The aim of this study is to determine vertebral levels of the coeliac trunk, the superior mesenteric artery, and the inferior mesenteric artery originated from the abdominal aorta and to calculate the distance measurements between these arteries and between these arteries and the aortic bifurcation by multidetector computed tomography angiography technique. It was determined that the nine different vertebral levels of the coeliac trunk, the nine different vertebral levels of the superior mesenteric artery, and the eleven different vertebral levels of the inferior mesenteric artery. The distance measurements between the coeliac trunk and the superior mesenteric artery, the inferior mesenteric artery, the aortic bifurcation were found significant between female and male. In this study, it was determined more different levels than the levels described in classical anatomy. The preoperative information of these morphological variations can contribute to the reduction of surgical time and perioperative vascular complications especially for anterior lumbar interbody fusion and defining the location of the primary lymphatic drainage site for gastrointestinal malignancies.

Introduction In the standard anatomy, the coeliac trunk, (CT) is the first ventral artery to emerge from the abdominal aorta (AA). It is usually located that above the pancreas, below the anterior of the hiatus aorticus and the level of the Th12-L1 intervertebral disc. The classical three branches of the CT are the left gastric artery, common hepatic artery and splenic artery that feed the liver, stomach, pancreas and the upper part of duodenum (Dăescu et al. 2017; Hemamalini 2018; Vandamme et al. 1969; Venieratos et al. 2013). The superior mesenteric artery (SMA) arises from the abdominal aorta at the level * Arzu Ekingen [email protected] 1

of the L1, typically 1.5 cm below the CT and just superiorly to the origin of the renal arteries. The SMA supplies blood to part of the duodenum, jejunum, ileum, right side colonies (caecum, appendix, colon ascendens), right 2/3 portion of the transverse colon, and part of the pancreas (Iannaccone et al. 2004; Niscoveanu et al. 2016). The inferior mesenteric artery (IMA) originates from left anterolateral aspect of the abdominal aorta approxi
