“…The ICA and ICV can be the site of rare anatomical variation, such as fenestration [14] or pathology, e.g. inflammatory aneurysm [20] or low-grade liposarcoma [21], but by and large their clinical significance lies in the right colectomy for cancer, either via open laparotomy, laparoscopy or robotic surgery [8,10,12,22].…”

“…Most of the studies concerning the ICA and ICV describe them as the most constant collaterals of the SMA and SMV [2,3,[10][11][12][13]. Therefore, the focus has been mostly on the ICV/ICA mutual topographic relations [12,14], on the type of ICA distal arborization [2,15], on the crossing pattern between ICA and SMV [9][10][11] or on the level of ICV termination on the SMV [10,16].…”

Aim The ileocolic vessels are important landmarks in advanced surgery of the midgut. The aim of the present study is to present variations of ileocolic vessels relevant to complete mesocolic excision with D3 lymphadenectomy of the right colon, within their detailed and precise morphometric framework and deriving from a large and consistent series of operated patients. Methods An ongoing prospective trial 'Safe Radical D3 Right Hemicolectomy for Cancer through Preoperative Biphasic Multidetector Computed Tomography Angiography' was reviewed. The imaging datasets underwent manual segmentation and 3D reconstruction, and the results were validated at surgery. A total of 356 patients were included in the study. Results A cross-section of the series revealed five cases (1.4%) with variation of ileocolic vessels relevant to complete mesocolic excision or D3 extended mesenterectomy. There were two cases with absence of a true classical ileocolic artery, two cases with absence of a true classical ileocolic vein, and one case of precocious bifurcation of the ileocolic artery, left to the superior mesenteric vein. The entire D3 area in all the cases was thoroughly documented and analysed from the morphometric point of view (calibres, lengths of vessels, crossing patterns). Conclusion The preoperative visualization of a patient's individual 3D anatomy is a powerful tool in identifying the variations whose negligence could have dire consequences in complete mesocolic excision of the right colon.
