Classic Common Hepatic Artery (CHA) from the celiac artery and the proper hepatic artery into right and left is seen in 55-60% of the population. A classification method was described by Michel et al. in 1955: I: standard anatomy ~60% (range 55-61%), II: replaced Left Hepatic Artery (LHA) ~7.5% (range 3-10%) III: replaced Right Hepatic Artery (RHA) ~10% (range 8-11 %) IV: replaced RHA and LHA ~1%,V: accessory LHA from Left Gastric Artery(LGA) ~10% (range 8-11%),VI: accessory RHA from Superior Mesenteric Artery (SMA) ~5% (range 1.5-7%),VII: accessory RHA and LHA ~1%,VIII: accessory RHA and LHA and replaced LHA or RHA ~2.5%, IX: CHA replaced to SMA ~3% (range 2-4.5%), X: CHA replaced to LGA ~0.5%. We present a case report of an 82 years old Caucasian man who suffered from left colic tumor with a CHA, LHA, RHA arising from SMA: IX Michel Classification. Angio-CT Abdominal Scan demonstrated absence of complete celiac trunk. Bipode and CHA, LHA, RHA arising from SMA. 3D image: SMA+CHA, celiak bipode.
