Background: The celiac trunk represents an unpaired visceral branch of the abdominal aorta, which detaches at the level of the 12th cervical vertebra. It has a trajectory of 1-2 cm and a caliber of 5-8 mm, having relations with the parietal peritoneum, the vestibule of the omental bursa, the diaphragmatic lymph nodes and the diaphragmatic pillar muscles, the caudate lobe of the liver, the vertical portion of the small gastric curvature and the median arcuate ligament. The celiac trunk trifurcates into three terminal branches: the left gastric artery, the common hepatic artery and the splenic artery. Each of these branches has a specific trajectory and relations, vascularizing the corresponding organs. Given its importance as a source of vascularization, any anatomical variation is eloquent and necessary to be known for the diagnosis and treatment of conditions at this level. Methods: The selection of articles that were included in this paper was made using the PubMed database, where the following keywords were used: variation of celiac trunk, celiac trunk and laparoscopic surgery, clinical implications of celiac trunk, celiac trunk and oncologic extensive surgery. Entering the mentioned keywords generated an initial number of 5428 references. They were subjected to a filtering process: duplicates were removed, only free full-text articles were selected, and inclusion and exclusion criteria were applied. Subsequently, the most appropriate articles for the topic of the paper were chosen, according to the Web of Science Impact Factor and suitability criteria, resulting in a final number of 28 articles. Literature review: These 28 articles were reviewed based on the criteria: anatomical variants in the branching of the celiac trunk, implications of anatomical variations of the celiac trunk in: laparoscopic surgery - treatment of median arcuate ligament syndrome, abdominal oncological surgery, liver transplant and interventional radiology. Conclusions: The anatomical variations of the celiac trunk have a significant impact on abdominal surgery, whether oncological or not, liver transplant, as well as minimally invasive radiological procedures. A correct knowledge of the up-mentioned variations significantly decreases the rate of intra- and post-interventional complications, accompanied by a smaller recovery time in the possible event of a complication, and also the general healing time following surgery.

Purpose: reviewing data on the anatomical variations of mandible and imaging data. Material and method: 10 studies were selected over a period of eighteen years (2013-2021), which have as object of study anatomical variations of mandible. A total of 482 patients were analyzed in imaging studies of anatomical variations of mandible, of which were 170 male and 312 were female. Results: The mandibular foramen was situated in the inferior 1/3 of mandibular ramus in 30 cases.(3-6). In 20 cases (40%) the mandibular foramen was situated in the middle of the ramus. Mental foramen was located on the anterior surface of the corpus of the mandible, posterior to the mental tubercle and had a round shape in 30 cases (60%). Mental foramen had an oval shape in 20 cases (40%). [ABSTRACT FROM AUTHOR]
