目的:探讨64排螺旋CT血管成像(CTA)在脑动静脉畸形(AVM)术后评价的应用价值。方法:39例脑AVM患者,术前均完善CTA检查,术后1周行CTA随访,术后1个月行DSA随访,由放射科医师与神经外科医师对术后CTA进行共同阅片,并与术前CTA及术后DSA进行对比分析。结果:CTA显示39例脑AVM均为单发,均行开颅切除,4例使用了动脉夹辅助;CTA对脑AVM术后残留评价的敏感度和准确度分别为100%、97.4%,DSA对脑AVM术后残留评价的敏感度和准确度均为100%,两者的诊断敏感度和准确度比较,差异无统计学意义(P〉0.05)。结论:应用CTA与DSA对脑AVM术后评价,CTA更为安全、方便,可作为首选方法。
Objective: To study the value of 64-row spiral CT Augiography ( CTA ) in postoperative of brain AVM. Method: 39 patients with brain AVM were completed the CTA examination of preoperative, and they all completed the CTA examination of postoperative review after f week, complete the DSA examination of postoperative review after 1 month, and to compare the images together by radiologists and neurosurgeons. Result: 39 patients with brain AVM were single, and removal of by craniotomy, 4 cases used the artery clamp in surgery; The postoperative residual of brain AVM that the sensitivity and accuracy of CTA was 100% and 97.4% respectively, and the sensitivity and accuracy of DSA was both 100%. There was no significant difference in the diagnostic sensitivity and accuracy ( P〉0.05 ) . Conclusion: For application of cerebral AVM postoperative evaluation results of CTA and DSA, the CTA is more safe, convenient, can be used as the preferred method.
