Materials and Methods: We included 100 patients who underwent CT angiography of the abdomen and pelvis. The branching patterns of the IMA were examined and classified as type 1 (bifurcated), including 1A (sigmoid and left colic arteries arising from a common trunk), 1B (sigmoid and superior rectal arteries arising from a common trunk) and 1C (sigmoid arteries arising from both trunks); type 2 (trifurcated); and type 3 (no left colic branch).  Results: Among the 100 patients evaluated, we found the variant to be type 1A in 9%, type 1B in 47%, type 1C in 24%, type 2 in 16%, and type 3 in 4%.  Conclusion: Preoperative CT angiography for evaluating the IMA branching pattern could inform decisions regarding the surgical approach to colorectal cancer.<\/jats:p>","DOI":"10.1590\/0100-3984.2023.0099","type":"journal-article","created":{"date-parts":[[2024,5,27]],"date-time":"2024-05-27T10:35:21Z","timestamp":1716806121000},"source":"Crossref","is-referenced-by-count":0,"title":["Evaluation
