CT肺动脉造影在肺栓塞诊断中的应用价值

Application of spiral CT pulmonary arteriography in diagnosis of pulmonary embolism

目的分析研究CT肺动脉造影在肺栓塞诊断中的应用价值。方法回顾性分析我院自2010年3月至2011年3月我院收治的25例肺栓塞患者的临床资料,总结CT检查特征。结果 25例患者均确诊为肺动脉栓塞,25例患者均见肺动脉腔内充盈缺损改变。6例出现中央性充盈缺损,呈双轨征和靶征;10例出现偏侧性充盈缺损;4例出现附壁性充盈缺损;5例出现完全性阻塞;部分患者可见肺梗死、支气管动脉扩张、胸腔积液和右室功能不全等肺动脉栓塞的间接征象。结论 CT检查对肺栓塞患者的临床诊断可提供较为客观的资料,可作为重要的辅助诊断方法使用。

Objective To discuss the value of spiral CT in the diagnosis of pulmonary embolism and its clinical used. Methods A retrospective analysis of clinical data was conducted in 25 patients with pulmonary embolism who were admitted in our hospital from March 2010 to March 2011 and the CT date were analyzed. Resuits The 25 suspected cases were diagnosed as pulmonary embolism. Diagnostic direct manifestations showed central in 6 cases, periphery in 10 cases, mural filling defects in 4 cases, and complete occlusion in 5 cases. Indirect signs showed pulmonary infarction, bronchial artery dilation, pleural effusion and right ventricular dysfunction. Conclusion Spiral CT is a uninjured diagnosis method for pulmonary embolism,and it is safe, quick and sensitive,it can help estimated the treatmentand effect.
