In the surgical video, the probability of presence of the right colic artery (RCA) was 21.2% (11\/52). On CT images, the RCA was present in 10 patients. The length of the origin of the middle colic artery (MCA) from its bifurcations was 2.33\u2009\u00b1\u20090.87\u2009cm measured intraoperatively using a sterile isometric filament, and the length measured using 3D\u2010CT vascular reconstruction was 2.36\u2009\u00b1\u20090.91\u2009cm; the difference was not statistically significant (<jats:italic>P<\/jats:italic>\u2009=\u20090.348). The length of the MCA and ICA initiation points was 3.22\u2009\u00b1\u20090.75\u2009cm measured intraoperatively using sterile isometric filaments and 3.36\u2009\u00b1\u20090.72\u2009cm measured using 3D\u2010CT vascular reconstruction, which was a statistically significant difference (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>3D\u2010CT vascular reconstruction can accurately predict the vessels related to right hemicolectomy in most cases.
