多层螺旋CT血管成像对下肢闭塞性动脉硬化症的应用价值

Multislice helical CT angiography of arteriosclerotic occlusive disease of lower limb

目的探讨多层螺旋CT血管成像(MSCTA)在诊断下肢闭塞性动脉硬化症病变中的应用价值。方法对临床确诊为下肢动脉病变患者30例,分别行MSCTA下肢动脉增强扫描和旋转数字减影血管造影(DSA)检查,按国际关节血管学会标准分别对DSA和MSCTA的诊断结果进行统计学分级并分型,比较MSCTA诊断同DSA之间的接近程度。结果MSCTA诊断区别狭窄分级结果与DSA比较差异无统计学意义(P>0.05)。结论MSCTA是诊断下肢动脉闭塞疾病的有效检查方法,具有和DSA相当的效能。

Objective To evaluate the diagnostic value of MSCTA in arteriosclerotic occlusive disease of lower limb. Methods 30 cases clinically suspected as arteriosclerotic occlusive disease of lower limb were performed CT and DSA angiography. Distinguish the result of MSCTA and DSA into classes separately acorrding to FICA standard and compare the MSCTA with DSA. Results Compared with the DSA, the differeces of the narrow classification diagnosis results of MSCTA were not significant （ P 〉 0.05 ）. Conclusion MSCTA is valuable to demonstrate arteriosclerotic occlusive lesion in artery of lower limb and classify as an accurate and non-invasive angiograpbic technique.
