A case of ergotism is presented to illustrate the role of duplex ultrasonography in
the diagnosis and management of this nonatherosclerotic cause of peripheral arterial
disease. Historical aspects of ergotism are discussed together with reference to the
relative vulnerability of different segments of the arterial circulation. Our case
emphasizes the potential for complete reversibility of the vascular changes if recognized
early.
