Acute aortic thrombosis in antithrombin III deficiency

M. E. Shapiro, R. Rodvien, K. A. Bauer and E. W. Salzman

Two cases of acute aortic thrombosis, a previously unreported complication of antithrombin III deficiency, are reported. Both patients had abnormally low antithrombin III levels, which improved to normal levels with warfarin ;sodium therapy. The possibility of antithrombin III deficiency should be considered in young patients with acute arterial thrombosis.
