血管超声与常规造影诊断下肢静脉血栓的价值比较

Comparison of value between vascular ultrasound and conventional radiography in diagnosing patients with venous thrombosis of lower extremities

目的比较血管超声检查与常规造影检查在下肢静脉血栓(LEVT)患者中的诊断价值。方法分析174例LVET患者的临床资料。随机分成观察组(血管超声检查)和对照组(常规造影检查),每组87例。比较2组患者的一般资料、诊断准确率、漏诊与误诊率、疾病形成因素及诊断结果。结果 2组患者的一般资料无显著差异(P>0.05)。观察组患者的总准确率显著高于对照组,总误诊漏诊率显著低于对照组(P<0.01)。2组患者疾病形成因素及诊断结果无显著差异(P>0.05)。结论LEVT患者采用血管超声检查进行诊断安全、无创、检出准确率高。

Objective To compare the value of vascular ultrasound and conventional radiography in diagnosing patients with venous thrombosis of lower extremities(LEVT).Methods Clinical data of 174 patients with LEVT was retrospectively analyzed.They were divided into observation group(vascular ultrasound)and control group(conventional radiography),87 cases in each group.The general information,the diagnostic accuracy,the missed diagnosis rate and misdiagnosis rate,the factors of disease formation and diagnostic results were compared between two groups.Results The general information showed no significant difference between two groups(P>0.05).The total diagnostic accuracy in observation group was significantly higher than that in control group,and the rates of missed diagnosis and misdiagnosis were significantly lower than control group(P<0.01).The factors of disease formation and diagnostic results showed no significant difference between two groups(P>0.05).Conclusion The vascular ultrasound for LEVT patients is safety and non-invasive,which has a higher diagnostic accuracy.
