摘　　要：目的探讨显微手术治疗硬脊膜动静脉瘘(SDAVF)前辅以CT血管成像(CTA)检查的临床治疗效果。方法 52例SDAVF患者术前行CTA检查和脊髓血管造影(DSA),确诊后行显微手术治疗。以DSA为金标准,计算CTA诊断的敏感度。采用Aminoff和Logue评分标准评价患者手术前后的脊髓功能。结果 CTA对52例SDAVF均做出正确诊断,对供血动脉及瘘口诊断的敏感度为100%。随访中有42例(87.5%)术后症状改善,无症状加重及复发者。结论 CTA可以准确定位诊断SDAVF的供血动脉及瘘口,是手术前必要的辅助检查。显微手术直接夹闭硬脊膜动静脉瘘口,可取得良好的疗效。Objective To investigate the efficacy of microsurgery combined with CT angiography （CTA） on spinal dural arteriovenous fistula （SDAVF）. Methods Fifty-two cases with SDAVF were diagnosed by CTA and selective spinal angiography were performed pre-operatively. Mierosurgery was carried out for all patients. Taking DSA as the golden stan-dard, the sensitivity of CTA was calculated. The function of the spinal cord was evaluated before and after treatment by us-ing the Aminoff and Logue scale. Results All 52 cases were correctly diagnosed with CTA. The sensitivity of CTA in re-vealing the feeding artery and fistula of SDAVF was 100%. The postoperative neurological status was improved in 42 pa- tients （87.5%）, no deterioration or recurrence was observed. Conclusion CTA can locate the site of SDAVF clearly and microsurgery is an effective approach for the treatment of SDAVF.
