Ectatic blood vessels in the mucosa and submucosa (hematoxylin and eosin stain, 4x magnification). This histologic change may be due to increased resistance to intestinal blood flow.

An elastin stain readily differentiates a vein from an artery by showing the absence of an arterial elastic lamina. In this Elastic Van Gieson stain (10x magnification), myointimal hyperplasia in the vein almost occludes the lumen (right). The artery is unaffected (left).
