[Chronic disseminated intravascular coagulation due to abdominal true aneurysm in two cases--effect of anti-platelet and anti-fibrinolytic therapy].

Case 1: 75 years old male was admitted to our hospital with anterior chest subcutaneous bleeding. Coagulation study revealed that fibrinogen and alpha 2-PI decreased, and FDP, FPA, B beta 15 approximately 42 and D-dimer increased. Case 2: 78 years old male was admitted to Shingu City Hospital with a left hip subcutaneous hematoma. Coagulation study revealed that fibrinogen, ATIII and alpha 2-PI decreased, and FDP increased. US and CT showed abdominal true aneurysm in both cases. Either severe infection or malignancy was not found. Ticropidine and T-AMCHA were medicated for 8 days in case 1, and for 18 months in case 2. Symptom and coagulation study improved in these cases. Due to some side effects such as appetite loss and liver dysfunction in case 1, and diarrhea in both cases, we changed the therapy to mini-dose heparin therapy. This therapy also proved effective. It is concluded that anti-platelet and anti-fibrinolytic therapy are effective for chronic DIC with abdominal true aneurysm.
