RESUMEN
A 74-year-old female underwent surgical treatment for adenocarcinoma of the pancreatic head. Preoperative multi-detector row computed tomography (MD-CT) demonstrated tumor invasion into the accessory right colic vein and the branch of the middle colic artery (MCA); which was not detected by digital subtraction angiography. MD-CT showed anatomical variants in the left hepatic artery arising from the left gastric artery; and the right posterior hepatic artery arising from the superior mesenteric artery. Three-dimensional reconstruction CT generated a clear picture of the anatomy of the region concerned; which is essential for a safe operation. The MD-CT findings were highly consistent with the intra-operative findings. We have demonstrated that MD-CT is an important and highly accurate modality for pancreatic surgery
