摘　　要：目的分析多层螺旋CT静脉造影(MSCTV)诊断髋部骨折术后下肢静脉血栓的价值。方法研究对象为2015年1月至2018年7月在本院接受髋部骨折且术后疑似DVT患者56例。回顾性分析其MSCTA影像学检查结果,并与DSA对照,分析MSCTA对髋部骨折术后下肢静脉血栓的诊断价值。结果所有患者下肢静脉均能清晰显示,18例未见异常,其余38例均可见不同程度的充盈缺损;以DSA为参照,MSCTA诊断髋部骨折患者下肢静脉血栓的灵敏度为95.00%、特异度为100.00%、准确率为96.42%、阳性预测值100.00%、阴性预测值88.89%、Kappa 0.915;且MSCTA与DSA在股静脉、股深静脉、腘静脉、胫后静脉血栓上的检出率一致,在髂静脉上MSCTA阳性率略高于DSA,但差异无统计学意义(P>0.05),且MSCTA、DSA检查期间均未见任意并发症发生。结论 MSCTA诊断髋部骨折术后下肢静脉血栓与DSA检查具较高的一致性,值得临床推介。Objective To analyze the value of multi-slice spiral CT venography(MSCTV)in diagnosising lower limb venous thrombosis after hip fracture.Methods 56 patients undergoing surgery for hip fractures in the hospital from January 2015 to July 2018 and with suspected DVT after surgery were enrolled in the study.The imaging findings of MSCTA were retrospectively analyzed and compared with DSA to analyze the diagnostic value of MSCTA for lower limb venous thrombosis after surgery for hip fracture.Results Veins in lower limbs of all patients could be displayed clearly.There were 18 cases without abnormalities and 38 cases with different degrees of filling defect.Referring to DS,the sensitivity,specificity,accuracy rate,positive predictive value,negative predictive value,and Kappa of MSCTA for the diagnosis of lower limb venous thrombosis in patients with hip fractures were 95.00%,100.00%,96.42%,100.00%,88.89%,and 0.915.MSCTA was consistent with DSA in the detection rates of femoral vein,deep femoral vein,popliteal vein,and posterior tibial venous thrombosis.The positive rate of MSCTAwas slightly higher than that of DSA in terms of iliac vein(P>0.05).No complications occurred during MSCTA or DSA.Conclusion The consistency between MSCTA and DSA is high for diagnosis of lower limb venous thrombosis after surgery for hip fracture.
