急性肺血栓栓塞症患者螺旋 CT 肺动脉造影影像学特点分析

摘要

目的：探讨急性肺血栓栓塞症（PTE）的螺旋 CT 肺动脉造影（CTPA）的影像学特点。方法收集急性 PTE患者的螺旋 CTPA 影像学资料，并对相关文献进行复习。结果本组病例65例，男37例，女28例，年龄26～63岁。CTPA 发现直接或间接征象者50例，直接征象表现为肺动脉内充盈缺损，而间接征象表现为右室和体循环、肺循环的继发性改变。结论急性 PTE 进行 CTPA 检查可表现为直接征象或是间接征象，影像科医师应掌握其影像学特点，做到早期诊断，以减少临床误诊率和病死率。%Objective To investigate the characteristics of spiral CT pulmonary angiography (CTPA) on patients with a‐cute pulmonary thromboembolism (PTE) .Methods The data of CTPA imaging on patients with acute PTE were collect‐ed and the relevant literatures were reviewed .Results There were 65 cases in this group ,including 37 males ,28 females , aged 26 to 63 years old .CTPA found direct or indirect signs in 50 cases ,and the direct signs showed pulmonary artery fill‐ing defect ,while the indirect signs showed right ventricular and systemic circulation ,pulmonary circulation secondary change .Conclusion Acute PTE examined by CTPA can be expressed as the direct or indirect signs ,radiology physicians should master its characteristics ,in order to make early diagnosis and treatment ,and to reduce clinical misdiagnosis rate and death rate .
