  • Title: Limb-threatening lower extremity ischemia successfully treated with intra-arterial infusion--case reports.
    Author: D'Amore MJ, Borge MA, Messersmith RN.
    Journal: Angiology; 1999 Mar; 50(3):233-7. PubMed ID: 10088803.
    Abstract:
    The authors present two patients with acute arterial vasospasm of the lower extremities causing marked ischemia. One patient had a history of Raynaud's disease, the second had been taking Cafergot for migraine headaches. Both patients's were given a test dose of intra-arterial tolazoline (50 mg). The patient with Raynaud's disease demonstrated marked improvement diffusely and was successfully treated with overnight infusion of papaverine. The second patient, taking Cafergot, demonstrated no angiographic response to tolazoline. It was speculated that the arteries of this patient were thrombosed. The patient was successfully treated with urokinase and remained free of pain at the 15-month follow-up.
