Skin necrosis after warfarin therapy.

M S Elliot, E J Immelman, P Jeffery

    South African Medical Journal = Suid-Afrikaanse Tydskrif Vir Geneeskunde
    |October 7, 1978

    Summary

    Skin necrosis is a rare, lethal complication of warfarin. If necrosis occurs, stop warfarin and start heparin, which prevents further necrosis from thrombosis.

    Area of Science:

    • Medical Science
    • Pharmacology
    • Pathology

    Background:

    • Coumarin-derivative anticoagulants, like warfarin, are widely used for thromboprophylaxis.
    • A rare but severe adverse effect of these drugs is skin necrosis.
    • Understanding the management of this complication is crucial for patient safety.

    Observation:

    • This report details a case of warfarin-induced skin necrosis.
    • The literature on coumarin-induced skin necrosis was reviewed.
    • The clinical presentation and pathological findings of this rare complication were analyzed.

    Findings:

    • Warfarin-induced skin necrosis is a thrombotic event.
    • Discontinuation of warfarin is recommended upon diagnosis of skin necrosis.
    • Immediate initiation of heparin therapy is crucial for managing this complication.

    Implications:

    • Heparin, unlike warfarin, does not cause skin necrosis.
    • Heparin can be safely administered for ongoing anticoagulation needs.
    • Prompt heparinization may prevent further thrombotic progression and mitigate necrosis development.
