Two cases of repeated upper gastrointestinal bleeding due to chronic disseminated intravascular coagulation associated with aortic aneurysm.

We describe two older patients with repeated bleeding due to gastric ulcers despite achieving endoscopic hemostasis. In both cases, laboratory tests suggested chronic disseminated intravascular coagulation, with an underlying aortic aneurysm identified as the cause of this bleeding. Both patients achieved successful hemostasis after supplementation with fresh frozen plasma, while surgical treatment of the underlying aneurysm was not feasible. Recurrent gastrointestinal bleeding warrants evaluation of coagulation abnormalities and screening for aortic pathology.
