[Ergotamine poisoning. Two cases of peripheral ischemia]

Ergotism is a rare disorder, generally caused by iatrogenia after the administration of drugs containing ergotamine derivates. Two cases of ischemic incidents at the extremities caused by a chronic intoxication with ergotamine tartrate, after its prolonged administration in therapeutical doses as a treatment for hemicrany, are reported. A short bibliographic review about semiology and therapeutic possibilities of such toxic pathology has been made.
