CT and clinical criteria for conservative treatment of supratentorial traumatic intracerebral haematomas.

In search of guidelines for the management of traumatic intracerebral haematomas (TICHs) with slight mass effects on computed tomography (CT) scans, the author reviewed the records of 29 patients who did not undergo surgery and 11 patients who did. It is found that patients with a TICH volume of less than 15 ml, a midline shift of less than 5 mm, an open perimesencephalic cistern on CT scans, a Glasgow Coma Scale (GCS) score of 12 or more, and an absence of lateralizing signs may be treated conservatively and expected to make a good recovery. On the other hand, with zero mortality and satisfactory outcomes, the patients under-going early surgery tended to have a TICH volume of more than 15 ml, a midline shift of more than 5 mm, an obliterated perimesencephalic cistern on CT scans, a GCS score of less than 12, and the presence of lateralizing signs. However, the position of such features as the criteria of early operation for a TICH is weakened by the retrospective nature of this study because some surgical patients, free of lateralizing signs in particular, might have managed to do well without craniotomy.
