CT血管造影在脑动静脉畸形诊断中的应用

目的探讨CT血管造影(CTA)在诊断脑动静脉畸形(AVM)中的应用价值。方法选择2010年1月至2013年5月入住连云港市第二人民医院21例AVM患者的影像资料,分析其CT平扫、增强扫描的影像表现,并与手术结果进行比较。结果 21例患者检测出21处AVM,均进行病灶手术切除。三维CTA影像结果和患者手术所见AVM结果进行对比显示:①CTA影像对AVM位置的诊断与手术结果一致,符合率高达100%。②CTA对供血动脉显示率为95.3%(41/43),对引流静脉的显示率为72.7%(24/33)。③21处畸形血管团采用三维CTA检测显示其累及范围与手术结果测量,比较差异无统计学意义(P>0.05)。结论 CTA是一种安全可靠的诊断AVM的影像手段,具有良好的临床诊断及手术指导应用价值。

Application of CTA in the Diagnosis of Cerebral Arteriovenous Malformations

Objective To explore the application value of CTA in the diagnosis of cerebral arteriovenous malformation （AVM）. Methods Twenty-one cases with AVM image data were randomly selected in Lianyungang Second People＇s Hospital, their CT plain scan, enhanced scan imaging were compared with the surgery results. Results In this study,21 patients were detected 21 AVM, and all were performed resection of lesions. The 3D CTA imaging results were compared with AVM findings in operation： （~） CTA imaging diagnosis was consistent with the AVM position of surgery results, with the coincidence rate as high as 100%. （~The CTA display rate of feeding artery was 95.3 % （41/43 ） , of the draining vein was 72.7 % （24/ 33 ）. （~Yl＇he 3D CTA displayed involvement scope of the 21 vaseldar malformations had no statistically signifi- cant difference from the surgery measured results （ P 〉 0.05 ）. Conclusion CTA is a safe and reliable dynamic imaging method for AVM diagnosis,with good clinical diagnosis and operation instructive and applicative value.
