摘要
目的探讨320排CT血管成像（CTA）对硬脊膜动静脉瘘（SDAVF）的诊治价值。方法回顾性分析11例SDAVF病人的临床资料，均行320排CTA及DSA检查，以病变的定性诊断、供血动脉、瘘口、引流静脉的显示情况及手术治疗效果等作为观察指标进行分析。结果320排CTA对11例病人均做出正确诊断，DSA首次检查漏诊2例，经行320排CTA获得相关图像信息后再行DSA检查发现病变。所有病人经手术治疗后随访3个月-2年，短期预后均良好，但术后9-12个月出现神经功能障碍加重3例。结论320排CTA可良好地立体显示SDAVF病灶的特征及其周围的骨性解剖结构，但其不能动态显示病灶的血流动力学改变，尚不能取代DSA检查。
Objective To estimate the diagnostic value of320-row CT angiography （CTA） for spinal dural arteriovenous fistula （SDAVF）. Methods Clinical data of 11 patients with SDAVF were analyzed retrospectively, and 320-row CTA and DSA were performed in all the patients. The main outcome measures such as etiologic diagnosis of the lesion, information of feeding artery, fistula, draining vein and surgical outcome were analyzed. Results All the 11 cases were correctly diagnosed by 320-row CTA and 2 misdiagnosed by DSA. The lesions in the 2 patients were found by DSA reexamination after gaining the image information by 320-row CTA. All the patients were followed up for 3 months to 2 years after the operation, with favorable prognosis in the short term, but nerve dysfunction deteriorated in 3 patients 9 to 12 months after operatiort Conclusions 320-rowCTAcanstereotacticallydisplaythelesioncharacteristicsandbonyanatomieal structure around SDAVF lesions, but can not dynamically display the hemodynamic change of lesions and can not replace DSA.
