CT血管造影在脑血管病诊治中的临床应用

目的评估CT血管造影（CTA）在脑血管病诊治中的价值。方法对60例脑血管病患者进行CTA检查，包括颅内动脉瘤31例、脑血管畸形15例、脑缺血性疾病4例和自发性颅内出血10例。除7例外其余患者同期均行数字减影血管造影（DSA）检查，并与CTA结果对照。结果52例CTA的结果与DSA相符。1例多发性动脉瘤，CTA漏检1个动脉瘤。7例本行DSA的患者，其CTA结果被手术或临床证实。CTA在描绘脑血管三维结构以及毗邻骨结构上优于DSA结去CTA是脑血管病诊断的一种简单，快速，非侵袭和可靠的方法。它特别适合于手术计划制定，术中定位以及长期系列随访。

Clinical Application of Computed Tomographic Angiography for Diagnosis and Treatment of Cerebrovascular Discases

Objective To assess the value of cerebrovascular diseases. Methods Sixty patients with cerebrovascular diseases were examined with CTA, including 31 cases of intracracranial aneurysms, 15 cases of cerebrovascular malformations, 4 cases of cerebral ischemic diseases and 10 cases of spontaneous intracranial hemorrhage. All except 7 cases also underwent digital subtraction angiography (DSA). Results In 52 cases, the results of CTA were confirmed by DSA. In a patients with multiple aneurysms, CTA detected one aneurysm but unrecognized by operations or clinical representation. CTA is superior to DSA for depicting the three - dimensional anotomy of cerebral vasculature and adjacent bone structure. Conclusion CTA is a simple, rapid, noninvasive and reliable method for diagnosis of cerebrovascular diseases. It is especially useful in the preoperative planning,intraoperative orientation and long-term follow-up.
