Abstract
Ergotism is a rare disorder associated with the iatrogenic administration of ergotamine in patients with migraine headaches. The intense vasospasm that occurs in this clinical condition results in acute limb ischaemia in the majority of cases.Two cases are presented of acute limb ischaemia in middle age female patients with signs and symptoms that threatened the viability of lower limbs. Duplex ultrasound and arteriography (in the first case) confirmed the presence of a bilateral diffuse arterial spasm. Ergotamine treatment was discontinued immediately and vasodilator therapy was administered. The patient's symptoms began to improve 48-72h after starting therapy.
