title: Buerger's disease and protein S deficiency: successful treatment with prostacyclin.
abstract: In this report we describe a female patient who presented with peripheral circulatory impairment. She had previously been thought to have a systemic vasculitis, but had failed to respond to corticosteroid and immunosuppressive therapy. Serologic investigations were negative. The patient was a very heavy smoker, and it became clear that her condition had many of the clinical features of Buerger's disease (thrombangiitis obliterans). The diagnosis was confirmed by angiography, and a coagulation screen showed her to have associated protein S deficiency. Her symptoms responded rapidly to cessation of smoking, warfarin therapy, and a series of intravenous prostacyclin infusions. We discuss in detail the possible pathologic mechanisms which might explain the association of protein S deficiency and thrombangiitis obliterans.
