摘 要: | 目的探讨CT血管造影(CTA)和数字减影血管造影(DSA)诊治颅内动静脉畸形的价值。方法对45例颅内动静脉畸形患者行CTA检查,三维重建采用最大强度投影(MIP)和容积成像显示(VR)技术;分析动静脉畸形显示情况并将结果与DSA和手术结果比较。部分动静脉畸形病例术后行CTA和DSA复查。结果CTA对颅内动静脉畸形的敏感性为93.33%,特异性为100%。能可靠地显示动静脉畸形的位置、形态、供血动脉和引流静脉。结论CTA是有效的血管成像技术,对颅内动静脉畸形有重要的诊治价值,临床疑诊为颅内动静脉畸形患者可作为一种筛选方法。CTA可作为动静脉畸形术后复查的方法之一。

Abstract: | Objective To explore the value of CT angiography (CTA) and digital subtraction angiography(DSA) in diagonosis and treatment of intracranial arteriovenous malformations (AVM). Methods 45 patients of the AVMs were examined prospectively with CTA. The data was performed 3D reconstruction with MIP and VR in all patients. We analyzed the AVMs showed by CTA and compared with DSA and operative feeling. Some patients underwent CTA and DSA after operation. Results The sensitivity and specificity of CTA in the detection of the AVMs were 93.33% and 100% respectively. The figure, location, main supplying arteries and most of draining veins of the AVMs were displayed very well on CTA. Conclusion CTA is a valuable method of angiography which has great value in diagnosis and treatment of AVMs. CTA can be used to screen patients with suspecting AVMs and is one of method in following up the operated patients. |
