摘要
目的：探讨多层螺旋ＣＴ血管成像对下肢动脉闭塞性疾病的诊断价值。方法：对２１例下肢动脉疾病病人采用多层螺旋ＣＴ血管造影技术（ＭＳＣＴＡ）显示下肢动脉粥样硬化狭窄、血栓闭塞性脉管炎和多发性大动脉炎等下肢动脉疾病的形态学改变，并结合部分病例的血管造影或手术结果评价多层螺旋ＣＴ血管造影的准确性。结果：与ＤＳＡ相比，ＭＳＣＴＡ显示下肢动脉主干狭窄和闭塞的符合率达１００％，对２级以上股动脉分支血管病变显示的阳性预测值为１００％，阴性预测值５０％，灵敏度９０％。结论：ＭＳＣＴＡ方法具安全、方便、准确、无创等特点，是下肢动脉疾病较理想的影像学检查手段。
Objectives: To study the value of multislice CT angiography(MSCTA) in diagnosing arterial diseases of the lower extremities. Methods: Twenty-one patients with arterial disease(s) of the lower extremities were submitted to MSCTA. In 11 cases, the MSCTA findings were compared to that of conventional angiography and/or by surgical operation. Results: Compared with DSA, MSCTA had a higher sensitivity in diagnosing stenosis and occlusion, a positive predictive value of 100% and negative predictive value of 50% were found in Grade Ⅱ branches of the femoral artery. Conclusions: MSCTA gives a higher accuracy and safety than conventional angiography in diagnosing arterial diseases of the lower extremities.
