Examples of resecatability assessment in untreated pancreatic ductal adenocarcinoma by means of computed tomography. A: Unresectability due to encasement of the common hepatic artery reaching to the celiac trunc (arrows); B: Borderline respectability with infiltration of the portal vein and one-sided contact to the common hepatic artery without extension to the celiac trunc. Neoadjuvant treatment and/or pancreatic left resection with en-bloc resection of the celiac trunc (after embolization) can be considered; C: Unresectability due to encasement of the superior mesenteric artery by more than 180º; D: Infiltration of the superior mesenteric vein and venous confluence with stenosis and multiple separated mesenteric venous branches unsuitable for surgical reconstruction.
