OBJECTIVETo report two cases of chronic disseminated intravascular coagulation associated (DIC) with aortic dissecting aneurysm, and discuss the treatment strategy.

METHODSThe clinical data of two patients with chronic DIC associated with aortic dissecting aneurysm were analyzed and the related literature was reviewed.

RESULTSCase 1: female, 53 years old, she had gingival bleeding, skin ecchymosis and haematuria for 2 months, the laboratory test revealed PLT 48 × 10⁹/L, APTT 38.0 s and fibrinogen 0.53 g/L; Case 2: male 86 years old, he had skin petechia and ecchymosis,gingival bleeding for 2 weeks, the laboratory test revealed PLT 17×10⁹/L, APTT 37.5 s and fibrinogen 0.51 g/L. CT scan for both cases revealed aortic aneurysm. They were diagnosed as aortic aneurysm associated chronic DIC. Both of them received blood component transfusion. After the treatment, they showed improvement in bleeding symptoms and laboratory data. They gave up operation, and were discharged from the hospital at last.

CONCLUSIONBlood replacement can alleviate bleeding tendency in those patients with chronic DIC associated with aortic dissecting aneurysm.
