摘　　要：本文探讨计算机体层扫描血管造影(CTA)检查在下肢血管闭塞病变中的应用价值及与血管腔内疗效的关系。选取经数字减影血管造影(DSA)确诊的93例下肢血管闭塞病变患者,采用CTA检查,分析CTA诊断病变部位结果、血管狭窄程度及与DSA诊断结果的一致性,并探讨CTA征象与患者血管腔内疗效的关系。结果显示,CTA诊断下肢血管闭塞病变部位、狭窄程度与DSA诊断结果均具有较高一致性(P<0.05);病变血管长度>1.41 cm、血管狭窄程度4级、病变血管远端CT值>62.65 Hu、钙化性斑块是下肢血管闭塞病变血管腔内治疗失败的危险因素(P<0.05)。CTA检查是诊断下肢血管闭塞病变的可靠方法,通过检查患者病变血管长度、血管狭窄程度、远端CT值及管腔内粥样斑块性质,有助于降低治疗盲目性,提高血管腔内治疗成功率。This study investigated the value of computed tomography angiography(CTA) in lower extremity vascular occlusion and its relationship with endovascular efficacy. A total of 93 patients with lower extremity vascular occlusion confirmed by digital subtraction angiography(DSA) were examined by computed tomography angiography(CTA). The results of CTA diagnosis, the degree of vascular stenosis and the consistency with DSA diagnosis were analyzed, and the relationship between CTA signs and endovascular curative effect was discussed. The results showed the location and degree of stenosis of lower extremity vascular occlusion diagnosed by CTA were highly consistent with those diagnosed by DSA(P<0.05). The length of diseased vessels >1.41 cm, the degree of vascular stenosis grade 4, the CT value of distal diseased vessels > 62.65 Hu and calcified plaque were the risk factors for the failure of endovascular treatment of lower extremity vascular occlusion(P<0.05). Conclusion CTA is a reliable method for the diagnosis of lower extremity vascular occlusion. By examining the length of diseased vessels, the degree of vascular stenosis, distal CT value and the nature of atherosclerotic plaque in the lumen, it can help to reduce the blindness of treatment and improve the success rate of endovascular treatment.
