Abstract

We studied the morphology of post-traumatic intracerebral hematoma. The relationship between hematoma morphology parameter-irregular rate (IR) and hematoma enlargement was also studied. One hundred and sixty-five patients with post-traumatic intracerebral hematoma were examined by brain CT scan within 72 h after the onset, and reexamined 120 h after onset. The two hematoma volumes (V1 and V2) were calculated. The curvature computing is proposed to describe IR of the hematoma. The relationship between hematoma IR and hematoma enlargement (V2-V1) was also analyzed. A significant difference was found in IR between patients with interval ≤ 3 hours and other intervals (P < 0.05, S-N-K method). Hematoma IR had a positive correlation with hematoma enlargement (P = 0.000; Spearman correlated coefficient, 0.893). It is useful for clinicians to gauge the possibility of hematoma enlargement with the aid of hematoma IR. It is valuable to repeat CT scans in time and apply active treatments in positive cases.
