title: Reversal of ergotamine-induced arteriospasm by mechanical intra-arterial dilatation.
abstract: Two patients with imminent gangrene of the extremities caused by ergot-induced arteriospasm underwent mechanical dilatation of the arteries when conventional measures such as anticoagulation, vasodilation, and sympathetic blockade produced no improvement. Dilatation by a balloon-tipped catheter produced an immediate and sustained reversal of the arteriospasm, together with a dramatic relief of symptoms and signs.
