Abstract

Aims: The study aim was to provide data on pattern and length of crossing of the ileocolic artery (ICA) and right colic artery (RCA) with the superior mesenteric vein (SMV).

Methods: Specimens from 30 fresh human cadavers underwent corrosion casting. Methylacrylate was injected into the SMV and superior mesenteric artery (SMA). Length of crossing was measured with a scaleable ruler and copper wire. Values are mean (SD; range).

Results: ICA was present in all specimens and crossed posterior to the SMV in 19 (63.33%) of 30 specimens. Length of crossing was 17.01 (7.84; 7.09-42.89) mm. RCA was present in 19 (63.33%) of 30 specimens. RCA crossed anterior to SMV in 16 (84.21%) of 19 specimens. Length of crossing was 20.63 (8.09; 6.3-35.7) mm.

Conclusions: ICA was always present, crossed posterior to SMV in 60% of specimens with a crossing length of 17 mm. RCA was present in 63% of specimens, crossed anterior to the SMV in 84% of specimens with a crossing length of 20 mm. Clinical implications include arterial length left behind with main nodes, arterial bleeding and safety of laparoscopic access.
