Aortic aneurysm-induced disseminated intravascular coagulopathy: successful surgical repair.

Aortic aneurysm is a rare cause of disseminated intravascular coagulopathy (DIC). We present the developmental course of DIC in a 70-year-old male patient who had a thoracoabdominal aortic aneurysm characterized by a progressive descending aortic aneurysm presenting as subcutaneous hemorrhage of acute onset. He was diagnosed as having aortic aneurysm-induced DIC. After adequate infusion of blood components, surgical repair of the descending aortic aneurysm was carried out successfully. The patient's bleeding tendency stopped dramatically in the early postoperative period as identified by clinical and laboratory findings. We concluded that the occurrence of DIC was due mainly to the progressive descending aortic aneurysm in the present patient and that surgical repair could be the definitive treatment of DIC in this setting.
