Evaluation of vascular involvement is important if surgical treatment is being considered. Arteriography demonstrating extensive encasement of the hepatic arteries or portal vein precludes curative resection. Combining the findings on cholangiography with those on arteriography has been found to have a greater accuracy in predicting unresectability. However, an occasional patient has compression of vascular structures rather than true malignant invasion.
