    ObjectivesCareful course observation is necessary for cases of mild to moderate traumatic brain injury even when disturbed consciousness is mild on admission. This is because delayed enlargement of hematoma and progression of cerebral swelling may occur and result in an emergency craniotomy. Here, we investigated coagulopathy and abnormal fibrinolysis as a predictive factor of "deterioration requiring surgery" in mild to moderate traumatic brain injury.Patients And MethodsSixty-one patients with mild to moderate (Glasgow Coma Scale (GCS) score 9-15) traumatic brain injury were admitted between June 2009 and October 2010. There were 54 subjects in the study, excluding those treated with oral antiplatelet agents and anticoagulants. Patients were classified into those with deterioration requiring surgery [op(+)] or those without deterioration requiring surgery [op(-)]. This was based on whether surgical treatment was performed for hematoma expansion, and exacerbated consciousness level within 3 days after admission. Age, GCS score on admission and blood test findings (platelet count, PT-INR, APTT, fibrinogen, FDP, and d-dimer) on admission were compared.ResultsThe op(+) and op(-) groups comprised 7 (13.0%) and 47 patients (87.0%), respectively. Platelet counts (24.8 vs 18.5 × 10(4)/μl) were decreased, and PT-INR (1.0 vs 1.2) was higher in the op(+) group. Specially, APTT (28.6 vs 39.1s), FDP (28.9 vs 112.9 μg/ml), and D-dimer (17.3 vs 69.6 μg/ml) values were significantly higher in the op(+) group.ConclusionsCoagulopathy and abnormal fibrinolysis, which are measurable in routine medical practice, is associated with deterioration requiring surgery in mild to moderate traumatic brain injury, indicating that careful course observation is necessary.Copyright © 2014 Elsevier B.V.
