The aim of the work: to inform about the variants of the anatomy of the coeliac trunk and the ramification of the left gastric artery.
Materials and Methods. All patients (n=175) who underwent CT of the abdominal cavity in the departments of functional diagnostics in 2020–2022 were studied retrospectively. Computed tomography of the abdominal cavity was performed using a 64-line scanner (Philips Brilliance). During the study, approximately 60–80 ml of non-ionic iodine-containing contrast was injected into the patients' ulnar vein. Scanning was carried out according to the standard protocol of computer diagnostics. Images were obtained from the level of the diaphragm to the wing of the iliac bones. Image analysis was performed using appropriate software.
Results and Discussion. Trifurcation of the coeliac trunk into the common hepatic artery, left gastric artery, and splenic artery (tripus Halleri, type I) was the most typical structural variant (94.29 %) in our observation. The remaining variants met with a low frequency. Adequate assessment of anatomical and topographical variations in the structure of the coeliac trunk and ramification of the left gastric artery in the preoperative period greatly facilitates the performance of all stages of endovascular intervention and minimizes the number of intra- and postoperative complications associated with erroneous embolization of other branches of the coeliac trunk.
