无创心血管超声检查在诊断肺动脉栓塞中的应用效果

Application Effect of Non-Invasive Cardiovascular Ultrasonography in the Diagnosis of Pulmonary Embolism

目的评估肺动脉栓塞中采用无创心血管超声检查的应用效果。方法回顾性选取在2019年6月—2021年6月期间济宁市兖州区中医医院超声医学科接诊的肺动脉栓塞患者200例,患者均接受常规超声检查、无创心血管超声检查,评估无创心血管超声检查在肺动脉栓塞中的应用价值。结果无创心血管超声检查的诊断准确率(95.50%)高于常规超声检查准确率(77.50%),差异有统计学意义(χ^(2)=27.746,P<0.001)。重度的肺动脉栓塞患者的肺动脉收缩压(80.65±8.46)mmHg及三尖瓣反流速度(4.04±0.42)m/s均显著高于反流程度为轻中度的肺动脉栓塞患者(51.56±8.52)mmHg、(3.01±0.33)m/s,差异有统计学意义(t=14.812、13.126,P<0.001)。异常情况分布:肺动脉栓塞直接征象占比32.50%、肺动脉收缩压升高占比80.50%、右心系统形态发生改变占比75.50%。临床特征表象:腔内血流缺损、充盈患者占比19.50%、附壁血栓现象占比13.00%、右心室扩大占比58.00%、右心房扩大占比71.50%。结论肺动脉栓塞中采用无创心血管超声检查的准确度高,可以为肺动脉栓塞患者临床治疗提供确切依据。

Objective To evaluate the application effect of non-invasive cardiovascular ultrasonography in pulmonary embolism.Methods A total of 200 patients with pulmonary embolism admitted to the Department of Ultrasound Medicine,Yanzhou District Traditional Chinese Medicine Hospital,Jining City from June 2019 to June 2021 were retrospective selected.All patients received conventional ultrasonography and non-invasive cardiovascular ultrasonography.Evaluated the application value of non-invasive cardiovascular ultrasonography in pulmonary embolism.Results The diagnostic accuracy of non-invasive cardiovascular ultrasonography(95.50%)was higher than that of conventional ultrasonography(77.50%),the difference was statistically significant(χ^(2)=27.746,P<0.001).The pulmonary artery systolic blood pressure(80.65±8.46)mmHg and tricuspid regurgitation velocity(4.04±0.42)m/s in patients with severe pulmonary embolism were significantly higher than those in patients with mild to moderate pulmonary embolism(51.56±8.52)mmHg,(3.01±0.33)m/s,the difference was statistically significant(t=14.812,13.126,P<0.001).The distribution of abnormal conditions:direct signs of pulmonary embolism accounted for 32.50%,increased pulmonary systolic blood pressure accounted for 80.50%,and morphological changes of the right heart system accounted for 75.50%.Appearance of clinical features:19.50%of patients with intraluminal blood flow defect and filling,13.00%with mural thrombosis,58.00%with right ventricular enlargement,and 71.50%with right atrial enlargement.Conclusion The accuracy of non-invasive cardiovascular ultrasonography in pulmonary embolism is high,which can provide an exact basis for the clinical treatment of patients with pulmonary embolism.
