目的：探讨CT血管造影（CTA）在诊断下肢动脉硬化闭塞症中的应用价值。方法回顾性分析57例经数字减影血管造影（DSA）确诊的下肢动脉硬化闭塞症患者的CTA检查资料。观察其狭窄程度，以DSA为金标准，计算CTA检查的敏感度、特异度、符合率、阴性预测值和阳性预测值。结果在狭窄程度的判断上，主髂动脉及股腘动脉的CTA与DSA具有极高的一致性。CTA诊断主髂动脉狭窄的敏感度、特异度、符合率、阴性预测值和阳性预测值分别为98.2%、95.3%、96.5%、98.8%、93.4%。CTA诊断股腘动脉狭窄的敏感度、特异度、符合率、阴性预测值和阳性预测值分别为96.8%、90.9%、95.2%、90.9%、96.8%。小腿动脉的CTA与DSA具有较高的一致性，一致性低于主髂动脉及股腘动脉，其敏感度、特异度、符合率、阴性预测值和阳性预测值分别为97.0%、87.2%、93.7%、93.8%、93.6%。结论 CTA是一种安全、可靠、无创的检查手段，能够准确地显示下肢动脉硬化狭窄的程度，并且与DSA检查具有较高的一致性，对下肢动脉硬化闭塞症具有较高的诊断价值。
目的：探討CT血管造影（CTA）在診斷下肢動脈硬化閉塞癥中的應用價值。方法迴顧性分析57例經數字減影血管造影（DSA）確診的下肢動脈硬化閉塞癥患者的CTA檢查資料。觀察其狹窄程度，以DSA為金標準，計算CTA檢查的敏感度、特異度、符閤率、陰性預測值和暘性預測值。結果在狹窄程度的判斷上，主髂動脈及股腘動脈的CTA與DSA具有極高的一緻性。CTA診斷主髂動脈狹窄的敏感度、特異度、符閤率、陰性預測值和暘性預測值分彆為98.2%、95.3%、96.5%、98.8%、93.4%。CTA診斷股腘動脈狹窄的敏感度、特異度、符閤率、陰性預測值和暘性預測值分彆為96.8%、90.9%、95.2%、90.9%、96.8%。小腿動脈的CTA與DSA具有較高的一緻性，一緻性低于主髂動脈及股腘動脈，其敏感度、特異度、符閤率、陰性預測值和暘性預測值分彆為97.0%、87.2%、93.7%、93.8%、93.6%。結論 CTA是一種安全、可靠、無創的檢查手段，能夠準確地顯示下肢動脈硬化狹窄的程度，併且與DSA檢查具有較高的一緻性，對下肢動脈硬化閉塞癥具有較高的診斷價值。

Objective To investigate the effectiveness of application of CTA (Computerized Tomography Angiography) in diagnosis of lower extremity arteriosclerosis obliterans.Methods CTA imaging data of iffty-seven lower extremity arteriosclerosis obliterans patients who had been conifrmed by DSA (Digital Subtraction Angiography) were analyzed retrospectively. Taking DSA as the standard, the degree of stenosis was observed and the sensitivity, specificity, coincidence rate, negative predictive value and positive predictive value detected by CTA were calculated.Results As for the degree of stenosis, the consistency of CTA and DSA in the aorto-iliac artery and femoropopliteal artery was almost perfect. The sensitivity, speciifcity, coincidence rate, negative predictive value and positive predictive value of CTA in diagnosis of aorto-iliac artery were 98.2%, 95.3%, 96.5%, 98.8% and 93.4% respectively, and which of femoropopliteal artery were 96.8%, 90.9%, 95.2%, 90.9% and 96.8% respectively. The consistency of CTA and DSA in diagnosis of crual artery was substantial, which was lower than aorto-iliac and femoropopliteal artery. The sensitivity, specificity, coincidence rate, negative predictive value and positive predictive value were 97.0%, 87.2%, 93.7%, 93.8% and 93.6% respectively.Conclusion CTA was a safe, reliable and noninvasive means. It could display the degree of stenosis of lower extremity arterial occlusive diseases accurately. And it had very high consistency with DSA in the diagnosis of lower extremity arterial occlusive diseases.
