[CT angiographic imaging of atypical arterial blood supply to the liver by the superior mesenteric artery].

Variations of the celiac trunk are seen in 25-35% of all patients. In 10-12% the right hepatitic artery arises from the superior mesenteric artery, the left hepatic artery in 4-5%. An aberrant origin of the common hepatic artery is seen in about 2.5%. We report about a patient with liver cell adenoma, in whom we diagnosed preoperatively the atypical origin of the common hepatic artery by performing CT angiography in the MIP technique (MIP = Maximum Intensity Projection). Conventional angiography as well as intraoperative findings confirmed the diagnosis.
