螺旋CT血管造影在急性脑血管病中的应用

The application of CT-angioraphuie in acute cerebrovascular diseases

目的 分析螺旋CT血管造影 (CTA)在急性脑血管病中的应用价值。方法 对发病2 4小时的大脑中动脉供血区梗死患者 2 1例、临床确诊的蛛网膜下腔出血患者 31例分别做CT平扫和CTA ,观察脑梗死或蛛网膜下腔出血患者颅内血管状况。结果 脑梗死组CT阳性率为 42 9% ,CTA阳性率为 71 4% ;CTA显示了梗死区的血管变化。蛛网膜下腔出血组CTA阳性率为 96 % ,同时清晰地显示动脉瘤与载瘤血管、动脉瘤与周围组织的关系。结论 在脑梗死的超早期诊断及确立蛛网膜下腔出血病因方面CTA不失为一种安全、快捷。

Objective To study the value of CT-Angioraphuie(CTA) applied in acute cerebrovascular diseases.Methods A CT planar scan and a CTA were carried out separately on a group of 21 patients with cerebral artery infarct 24 hours after the onset of the disease and a group of 31 patients with established diagnosis of subarachnoid hemorrhage and then observing each patient’s vascular condition.Results In the infarct group,a CT scan returned to positive in 42 9% of patients and the CTA returned to positive in 71 4% of patients.The CTA also showed changes in the infarct patients’ blood vessels.In the subarachnoid hemorrhage group,the CTA scan nad positive results in 96% of patients.The CTA also showed clearly the relationship between the aneurysm and its carrier artery, and the relationship between the aneurysm and the surrounding tissue.Conclusion From the viewpoint of diagnosing cerebral infarct and subarachnoid hemorrhage,CTA proves to be a valuable tool that is safe,fast and reliable in examining minuscule aberrations.
