[The "hepatoceliac collateral" in complete hepatomesenteric trunk--a first angiography observation]

In the example presented here we determined a complex anomaly of the large arterial vessels of the upper abdomen in combination with an intrahepatic vascular malformation (partially thrombosed haemangioma), this identification having become possible by superselective arteriography. There were two anastomoses of considerable calibre besides a complete truncus hepatomesentericus. We named one of these "hepato-coeliacal collateral". This collateral is now being described for the first time in literature and is demonstrated via angiography. Taking into account the embryogenesis of the visceral arteries and the organogenesis of the upper abdominal organs, we offer an interpretation of the development possibilities of the "hepato-coeliacal collateral".
