目的 :探讨CT血管造影 (CTA)技术在神经外科临床应用的价值 .方法 :CTA检查 42例 ,在CTA检查 3～ 5d后行数字减影血管造影 (DSA)进一步检查 ,用DSA检查结果与CTA的结果进行对比、分析 .结果 :CTA发现异常 30例 ;其中脑动脉瘤 (CAn) 12例、脑动静脉畸形 (AVM ) 8例、颈内动脉病变 5例、脑膜瘤 3例、颈内动脉海绵窦漏 1例、小脑血管网织细胞瘤 1例 ,其余 12例CTA未能发现异常 .与DSA检查结果基本相符合 .结论 :CTA检查对神经外科疾病尤其对脑血管疾病是一种快捷、无创、准确、立体、经济的检查方法 ,且对了解肿瘤供血 ,指导临床手术治疗有着重要的临床价值
Objective: To investigate the clinical value of CT angiography (CTA) in neurosurgery.Methods: CTA was performed in 42 cases, further examined by digital subtraction angiography (DSA) 3 ~ 5 days after CTA, and compared with CTA (CAn) in 12 cases, cerebral arteriovenous malformation (AVM) in 8 cases, internal carotid artery disease in 5 cases, meningioma in 3 cases, internal carotid artery 1 case of cavernous sinus leak, 1 case of cerebellar retinoblastoma, and the other 12 cases of CTA failed to find abnormalities.Conclusion: The CTA examination of neurosurgical diseases, especially for cerebrovascular disease is a fast, Non-invasive, accurate, three-dimensional, economical inspection methods, and to understand the tumor blood supply, clinical surgery has important clinical value
