복부 대동맥류에서 발치 후 발생한 범발성 혈관내 응고증 1 예

Disseminated intravascular coagulation (DIC) is the result of a severe underlying disorder thatinitiates massive activation of the coagulation system. We report an unusual case of 79- year - old man who developed DIC after tooth extraction in abdominal aortic aneurysm. He was referred to our hospital because of persistent bleeding after tooth extraction. Physical examination indicated a pulsating mass in abdomen. Abdominal computerized tomography (CT) scan revealed 70 mm diameter aneurysm of the abdominal aorta, extending from the renal infrahilar level to the common iliac artery, and his coagulation profile showed the features of DIC by revealing thrombocytopenia, hypofibrinogenemia, and increased level of fibrinogen degradation product (FDP). After he had received blood component therapy including fresh frozen plasma and continuous intravenous heparin infusion (4,800 U/day), the bleeding diathesis and coagulopathy improved. He refused to have definitive surgery for the aneurysm. (Korean J Med 61:572- 576, 2001)
