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。
Objective To evaluate the value of CT angiography (CTA) in the diagnosis and treatment of cerebrovascular disease. Methods Sixty patients with cerebrovascular disease underwent CTA, including 31 cases of intracranial aneurysm, 15 cases of cerebrovascular malformations, 4 cases of cerebral ischemic disease and 10 cases of spontaneous intracranial hemorrhage. All patients underwent digital subtraction angiography (DSA) during the same period except for 7 cases and were compared with CTA results. Results The results of 52 CTAs were consistent with DSA. 1 case of multiple aneurysms, CTA missing an aneurysm. Seven patients with DSA in our hospital had their CTA results surgically or clinically confirmed. CTA is superior to DSA in depicting the three-dimensional structure of cerebral blood vessels and the adjacent bone structure. CTA is a simple, rapid, noninvasive and reliable method for the diagnosis of cerebrovascular disease. It is particularly suitable for surgical planning, intraoperative positioning and long-term series of follow-up.
