常规超声联合无创心血管超声鉴别诊断肺动脉栓塞与深静脉血栓的价值研究

Study on the value of conventional ultrasound combined with non-invasive cardiovascular ultrasound in the differential diagnosis of pulmonary artery embolism and deep vein thrombosis

目的分析肺动脉栓塞与深静脉血栓应用常规超声联合无创心血管超声鉴别诊断的意义。方法60例肺栓塞患者,均接受常规超声与无创心血管超声诊断,记录常规超声及常规超声联合无创心血管超声对肺动脉栓塞和深静脉栓塞的检出情况,并以肺动脉造影检查结果为金标准,对比两种诊断方式的敏感性、特异性、准确性。结果经常规超声联合无创心血管超声诊断,共发现肺动脉栓塞患者31例,深静脉栓塞患者23例,诊断敏感性、特异性、准确性分别为93.94%(31/33)、85.19%(23/27)、90.00%(54/60);经单纯常规超声诊断,共发现肺动脉栓塞患者24例,深静脉栓塞患者15例,诊断敏感性、特异性、准确性分别为72.73%(24/33)、55.56%(15/27)、65.00%(39/60)。常规超声联合无创心血管超声诊断的敏感性、特异性、准确性均高于常规超声诊断,差异有统计学意义(P<0.05)。结论常规超声联合无创心血管超声检查在鉴别诊断肺动脉栓塞和深静脉栓塞中的价值颇高,值得临床深入推广。

Objective To analyze the differential significance of conventional ultrasound in combination with non-invasive non-invasive cardiovascular ultrasound in differential diagnosis of pulmonary embolism and deep vein thrombosis.Methods All 60 patients with pulmonary embolism were diagnosed by conventional ultrasound and non-invasive cardiovascular ultrasound,and the detection of pulmonary artery embolism and deep vein embolism by conventional ultrasound and conventional ultrasound combined with non-invasive cardiovascular ultrasound was recorded.The sensitivity,specificity and accuracy of the two diagnostic modalities were compared using pulmonary arteriography findings as the gold standard.Results Conventional ultrasound combined with non-invasive cardiovascular ultrasound diagnosis found 31 cases of pulmonary embolism and 23 cases of deep vein embolism.The sensitivity,specificity and accuracy of diagnosis were 93.94%(31/33),85.19%(23/27)and 90.00%(54/60),respectively.Conventional ultrasound diagnosis found 24 cases of pulmonary embolism and 15 cases of deep vein embolism.The sensitivity,specificity and accuracy of diagnosis were 72.73%(24/33),55.56%(15/27)and 65.00%(39/60)respectively.The sensitivity,specificity and accuracy of conventional ultrasound combined with noninvasive cardiovascular ultrasound were higher than those of conventional ultrasound,and the differences were statistically significant(P<0.05).Conclusion Conventional ultrasound in combination with non-invasive cardiovascular ultrasound is of great value in the differential diagnosis of pulmonary embolism and deep vein thrombosis,and it is worthy of further promotion in clinical practice.
