目的 探析螺旋CT检查在基底 节区高血压脑出血患者术后血吸收程度 中的评估作用。方法 收集我院2013年6 月-2015年12月所收治经头部CT检查确诊 的基底节高血压脑出血患者74例作为研 究对象，均使用Lightspeed CT扫描机进 行头颅CT检查，于术后3个月应用改良 Rankin评分(即mRs评分)评估预后，观察 治疗前后患者头颅CT检查的影像表现，比 较预后良好及预后不佳患者的血肿吸收情 况。结果 基底节区高血压脑出血术前螺 旋CT影像主要表现为高密度影、边缘清 晰，形态以类球形规则为主，同侧脑组织 及脑室结构受压发生移位或中线结构偏 移, 颅内存在散在游离气体影；术后高密 度影范围缩小，颞顶部可见致密穿刺针与 大量金属伪影，病灶周围低密度包绕影与 颅内散在游离气体影均减少。结论 CT影 像对脑出血部位、出血量、血肿形态、破 入脑室情况具有良好显示，利于术前病情 评估及术后血肿吸收的确认，有助于预后 预测，具有较大推广价值。

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.
