Abstract
To the Editor: With regard to the excellent review of warfarin by Wessler and Gitel (Sept. 6 issue),1 the importance of protein C in preventing thrombosis in patients treated with warfarin has recently been emphasized by two reports of the development of skin and soft-tissue necrosis in warfarin-treated patients with a hereditary protein C deficiency.2,3 A review of 17 previously reported cases of warfarin necrosis revealed that in all but 2 the onset of thrombosis coincided with prothrombin times that exceeded the therapeutic range, and it occurred within the first five days of treatment, suggesting extreme sensitivity to the hypoprothrombinemic.
