Arteries distended normally with blood were removed from dogs in vivo using a special double hemostat. Some of their anatomic features were compared with those of similar collapsed vessels conventionally obtained postmortem. An intimal layer was not found in distended arteries from young, healthy dogs, the endothelium being tightly compressed against the internal elastic lamina. An intima was formed in some collapsed vessels from the same animals, however. The thickness of the layer was increased in arteries from aging dogs, and in the presence of degenerative changes in the wall. A possible mechanism for the formation of the intima is suggested.

    Fibrornuscular dysplasia (FMD) is a noninflammatory, nonatherosclerotic disease of the vascular system, that can affect intima, media, or adventitia. The dysplasia in these layers leads to decrease in the lumen and increased turbulence leading to diminished flow through the affected portion. The...
