Chronic ergot toxicity: A rare cause of lower extremity ischemia.
Chronic ergot toxicity is a rare cause of lower extremity ischemia. The cornerstone of therapy in ergot toxicity is to discontinue the use of caffeine, cigarettes, and all ergot-containing medications. Although multiple different therapies have been recommended for acute toxicity, no specific treatment is uniformly recommended in chronic toxicity. We present a case of long-term ergot use for migraine headaches in a woman who had severe chronic lower extremity claudication. This case demonstrates the unique features associated with the diagnosis and management of chronic ergot toxicity. We recommend a conservative approach consisting of observation, antiplatelet agents, and the discontinuance of ergots. If symptoms progress to rest pain or gangrene, surgical treatment should be considered.
