摘　　要：目的观察CT血管成像(CTA)诊断脊髓血管畸形(SCVM)的价值。方法回顾性分析85例经手术确诊SCVM患者CTA及数字减影血管造影(DSA)资料,以术中所见及术后临床诊断为金标准,计算CTA判断病变类型和范围的准确率,以及CTA显示增粗供血动脉及瘘口位置与DSA的符合率。结果85例SCVM包括硬脊膜动静脉瘘(SDAVF)59例、脊髓周围动静脉瘘(SPAVF)10例、脊髓动静脉畸型(SAVM)12例及海绵状血管瘤(CM)4例。CTA判断病变类型和范围的准确率分别为85.88%(73/85)和92.94%(79/85)。除4例CM CTA及DSA结果均为阴性外,CTA显示81例SCVM供血动脉及瘘口位置与DSA的符合率分别为86.42%(70/81)和82.72%(67/81)。结论脊髓CTA能较准确显示CM之外大部分SCVM病变范围、供血动脉及瘘口位置。Objective To explore the value of CT angiography(CTA)for diagnosing spinal cord vascular malformation(SCVM).Methods Spinal cord CTA and digital subtraction angiography(DSA)data of 85 patients with SCVM confirmed by postoperation pathology were retrospectively analyzed.Taken the intraoperative findings and postoperative clinical diagnosis as the gold standards,the diagnostic accuracy of CTA for judging the type and extent of SCVM,and the consistence rate of CTA for displaying the feeding artery and fistula location with DSA were calculated.Results Among 85 SCVM cases,there were 59 cases of spinal dural arteriovenous fistula(SDAVF),10 cases of spinal perimedullary arteriovenous fistula(SPAVF),12 cases of spinal arteriovenous malformation(SAVM)and 4 cases of cavernous malformation(CM).The diagnostic accuracy of CTA for judging the type and extent of SCVM was 85.88%(73/85)and 92.94%(79/85),respectively.Except for 4 cases of CM with negative results of both CTA and DSA,the consistence rate of CTA in displaying the feeding artery and fistula location with DSA in 81 cases of SCVM was 86.42%(70/81)and 82.72%(67/81),respectively.Conclusion For most SCVM cases except CM,spinal CTA could accurately display lesion extent,feeding artery and the location of fistula.
