Objective To explore the effects of spiral CT in evaluation of postoperative blood absorption in patients with hypertensive cerebral hemorrhage in basal ganglia. Methods 74 patients with hypertensive cerebral hemorrhage in basal ganglia diagnosed by head CT who were treated in our hospital between June 2013 and December 2015 were selected as the study objects. All patients underwent head CT with Lightspeed CT scanner. 3 months after operation, modified Rankin score (MRS score) was used to evaluate the prognosis. The imaging findings of head CT were observed before and after treatment. The status of hematoma absorption was compared between patients with good prognosis and poor prognosis. Results The imaging findings of preoperative spiral CT of hypertensive cerebral hemorrhage in basal ganglia showed high density shadow, clear edge, round-likely and regular shape. The ipsilateral brain tissues and ventricular structures were compressed and shifted or midline shifted. There was scattered intracranial free gas; After operation, the range of high density shadow narrowed. The top of temporal was with presence of dense puncture needle and a lot of metal artifacts. There was low density wrapped shadow around the lesions and the scattered intracranial free gas was reduced. Conclusion CT can well display site of cerebral hemorrhage, bleeding volume, shape of hematoma and breaking into ventricle. It is conductive to the evaluation of preoperative condition and confirmation of postoperative hematoma absorption, which is good for predicting prognosis and has great value of promotion.
