分析采取无创心血管超声诊断深静脉血栓与肺动脉栓塞的效果

Analyze the effect of noninvasive cardiovascular ultrasound in the diagnosis of deep vein thrombosis and pulmonary embolism

目的:对无创心血管超声在肺动脉栓塞患者中的诊断价值进行探讨。方法:选取2019年6月—2021年6月聊城市妇幼保健院收治的肺动脉栓塞患者80例,采用彩色多普勒超声诊断仪进行诊断,对患者肺动脉收缩压以及三尖瓣反流速度进行观察。结果:80例患者中,确诊为肺动脉栓塞的有75例,其余5例未发现异常现象,诊断准确率为93.75%。75例确诊患者中,右心系统形态改变的患者占比为40.00%,直接征象的患者占比为37.33%,并发下肢深静脉血栓的患者占比为22.66%;中轻度反流患者三尖瓣反流速度和肺动脉收缩压低于重度反流患者,差异具有统计学意义(P<0.05)。结论:无创心血管超声能够对患者栓塞情况进行有效诊断,不仅方式方便,而且方法快捷,可以在临床广泛应用。

Objective To analyze the role of non-invasive cardiovascular ultrasound in the diagnosis of deep vein thrombosis in patients with pulmonary embolism.Methods 80 patients with pulmonary embolism treated in Liaocheng Maternal and Child Health Hospital from June 2019 to June 2021 were diagnosed.Color Doppler ultrasonography was used for diagnosis,and pulmonary artery systolic blood pressure and tricuspid regurgitation velocity were observed.Results Of the 80 patients,75 patients were diagnosed with pulmonary embolism,and 5 cases were not abnormal.The diagnostic accuracy rate was 93.75%;among them,37.33%had direct signs,40.00%had right heart system morphological changes,22.66%Of patients were complicated by deep venous thrombosis of the lower extremities;tricuspid regurgitation velocity and pulmonary systolic pressure in patients with moderate and mild regurgitation were lower than those in patients with severe regurgitation,the difference was statistically significant(P<0.05).Conclusion Non-invasive cardiovascular ultrasound can effectively diagnose embolism in patients.It is not only convenient,but also quick,and can be widely used in clinical practice.
