目的:探讨CT血管成像(CTA)对头部血管性病变的临床应用价值.方法:对30例脑血管病患者进行常规头颅CT平扫加CTA检查,并对其图像进行对比分析.结果:头颅CT平扫表现为颅内出血8例,蛛网膜下腔出血14例,正常8例.而CTA检查显示动脉瘤16例,动静脉畸形6例,动脉狭窄4例,动脉硬化1例,正常3例.结论:CTA可做为脑血管疾病的诊断和介入治疗筛选的方法,尤其可做为脑动脉瘤和动静脉畸形所致蛛网膜下腔出血的首选检查方法.
Objective: To investigate the clinical value of CT angiography (CTA) in the treatment of head vascular lesions.Methods: Thirty patients with cerebrovascular disease underwent conventional CT scans and CTA examinations, and the images were compared.Results: CT showed 8 cases of intracranial hemorrhage, subarachnoid hemorrhage in 14 cases, normal in 8. CTA showed aneurysm in 16 cases, 6 cases of arteriovenous malformations, 4 cases of arterial stenosis, 1 case of atherosclerosis, normal 3 cases .Conclusion: CTA can be used as a diagnostic and interventional therapy screening method for cerebrovascular disease, especially as a preferred method for detecting subarachnoid hemorrhage caused by cerebral aneurysm and arteriovenous malformations.
