  • Title: Conservative treatment of inoperable arterial occlusions of the lower extremities with intra-arterial prostaglandin E1.
    Author: Gruss JD, Bartels D, Ohta T, Machado JL, Schlechtweg B.
    Journal: Br J Surg; 1982 Jun; 69 Suppl():S11-3. PubMed ID: 7044465.
    Abstract:
    Prostaglandin E1 has a strong vasodilator effect, it inhibits the aggregation of platelets and improves the microcirculation. The hormone is synthesized from arachidonic acid and 80-90 per cent is eliminated in the first transit of the pulmonary circulation. From 1 January 1978 to 30 June 1981 100 patients suffering from inoperable occlusion of the arteries of the lower limbs and facing amputation were treated with intra-arterial PGE1 by prolonged perfusion over an average period of 34 days. PGE1 0.1-0.2 ng kg-1 body weight min-1 was administered. Forty-seven of 100 legs were saved; 22 of 29 patients suffering from diabetes requiring insulin had to undergo amputation, but only 1 of 18 patients suffering from thromboangiitis obliterans had to have an amputation. The results of treatment in the 52 cases of uncomplicated arteriosclerosis lie in between, with 18 amputations. The complications that followed treatment were haemorrhage, arterial thrombosis, infection and mycotic aneurysms.
