摘　　要：目的分析256排螺旋CT肺动脉造影诊断肺动脉栓塞的临床价值及其可行性。方法将2018年6月至2019年6月期间因肺动脉栓塞于我院进行治疗的55例患者作为研究对象,所有患者在入院后均采用256排螺旋CT肺动脉造影以及肺通气/灌注显像检查,对比两种检查方式对患者疾病的检出情况、灵敏度、特异性等指标的差异,并对螺旋CT肺动脉造影结果进行细致分析。结果观察组对肺动脉栓塞的检出率明显高于对照组(P<0.05);观察组检查方案实施后诊断灵敏度与特异性均明显高于对照组(P<0.05);本研究收治的55例患者共累及205处肺动脉及其分支,主要累及分支部位包括右侧(69.76%)、下肺动脉及其分支(63.41%)、叶及段动脉(66.83%)。结论针对肺动脉栓塞进行临床诊断时,256排螺旋CT肺动脉造影的应用可明显提高患者疾病检出率,在有效掌握患者栓塞形态与部位的同时还能明确其诊断征象,为后续治疗方案的制定及改善提供数据支持,值得推广应用。Objective To analyze the clinical value and feasibility of 256-slice spiral CT pulmonary angiography in the diagnosis of pulmonary embolism.Methods A total of 55 patients who underwent pulmonary embolization in our hospital from June 2018 to June 2019 were enrolled.All patients underwent256-slice spiral CT pulmonary angiography and pulmonary ventilation/perfusion imaging after admission.Compare the differences in the detection,sensitivity,and specificity of the two types of examination methods,and analyze the results of spiral CT pulmonary angiography.Results The detection rate of pulmonary embolism in the observation group was significantly higher than that in the control group(P<0.05).The sensitivity and specificity of the observation group were significantly higher than those in the control group(P<0.05).A total of 205 pulmonary a rteries and their branches were involved in 55 patients,including the right side(69.76%),the lower pulmonary artery and its branches(63.41%),and the leaf and segmental a rteries(66.83%).Conclusion The clinical application of 256-slice spiral CT pulmonary angiography can significantly improve the disease detection rate of patients with pulmonary embolism.It can also clearly understand the diagnostic signs of patients with embolization morphology and location,which helps develop the follow-up treatment plan.And improve the provision of data support;it is worth promoting.
