A Classification of Consumption Coagulopathy Associated with Abdominal Aortic Aneurysm / 日本心臓血管外科学会雑誌

ABSTRACT

Fifty consecutive patients who underwent elective repair for abdominal aortic aneurysms were preoperatively evaluated on blood coagulation tests and retrospectively classified into three groups. Class I had a normal profile on the tests. Class II had either high FDP (≥20ng/ml), TAT (≥20ng/ml), or positive results on the FM test. Class III had either thrombocytopenia (≤120/μl) or bleeding symptoms with Class II conditions. Operative mortality was 0% (0/26) in Class I, 13% (2/15) in Class II, and 22% (2/9) in Class III patients. This classification is considered to be simple and useful to assess specific coagulopathy for aortic aneurysms.
