Isolated Iliac Artery Aneurysms Associated with Disseminated Intravascular Coagulation (DIC)

Abstract

An 84-year-old man was referred to our hospital on December 3, 1993, because of excessive bleeding after tooth extraction. Coagulation studies revealed thrombocytopenia (2.2 x 104/μ1), increased serum levels of FDP-E (3172 ng/ml) and D dimer (42.6 μg/ ml), and increased plasma levels of thrombin-antithrombin III complex (48.0 ng/ml) and plasmin-α2-plasmin inhibitor complex (6.8 μg/ml). Computed tomography showed bilateral common iliac artery aneurysms. A diagnosis of DIC due to bilateral common iliac artery aneurysms was made. Heparin (10,000 U/day) administered to treat DIC resulted in good control, and operative repair of the aneurysms was successfull. This is the second reported case of isolated iliac artery aneurysms associated with DIC. © 1995, The Japan Geriatrics Society. All rights reserved.
