Cystic adventitial degeneration of the popliteal artery. Report of a case.

A case of cystic adventitial degeneration of the popliteal artery is described. This is an unusual cause of intermittent claudication, but the diagnosis should be suspected in young persons, especially men, where the arteriogram shows a stenosis due to compression and arteriosclerotic changes are not demonstrable. A brief review of the literature on the condition, diagnosis, and treatment is given.
