Recently, in addition to the middle colic artery and left colic artery (<jats:styled-content style=\"fixed-case\">LCA<\/jats:styled-content>), the accessory middle colic artery (<jats:styled-content style=\"fixed-case\">AMCA<\/jats:styled-content>) has been recognized as a feeding artery for the left\u2010sided colon. This study aimed to evaluate the vascular anatomy of the splenic flexure focusing on the <jats:styled-content style=\"fixed-case\">AMCA<\/jats:styled-content> in a large number of patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>A total of 734 patients who underwent <jats:styled-content style=\"fixed-case\">CT<\/jats:styled-content> before surgery for colorectal cancer were enrolled. We retrospectively evaluated the vascular anatomy using both two\u2010 and three\u2010dimensional <jats:styled-content style=\"fixed-case\">CT<\/jats:styled-content> angiography.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The <jats:styled-content style=\"fixed-case\">AMCA<\/jats:styled-content> existed in 36.4% of the cases (<jats:italic>n<\/jats:italic> = 267).

The <jats:styled-content style=\"fixed-case\">AMCA<\/jats:styled-content> had a common trunk with the transverse pancreatic artery in 54 patients (20.2%). The frequency of the presence of the <jats:styled-content style=\"fixed-case\">AMCA<\/jats:styled-content> was associated with the branching pattern of the <jats:styled-content style=\"fixed-case\">LCA<\/jats:styled-content>, and was more frequent when the <jats:styled-content style=\"fixed-case\">LCA<\/jats:styled-content> was absent (<jats:italic>P<\/jats:italic> &lt;
