彩色多普勒超声诊断腹主动脉夹层动脉瘤

Diagnosis of abdominal aortic dissection aneurysm with color Doppler flow imaging

目的 应用彩色多普勒超声诊断腹主动脉夹层动脉瘤。方法 应用彩超测量腹主动脉内径 ,观察腹主动脉及其分支内膜分离的部位和范围 ,以及鉴别真假腔。结果 内膜分离是本病最可靠的诊断依据 ,血流分隔现象、动脉扩张和管腔内血栓等具有重要的辅助诊断价值。彩超能很好地鉴别真假腔和诊断夹层动脉瘤破裂。结论 彩超能正确地评价本病受累血管 ,是诊断腹主动脉夹层动脉瘤的一种较为可靠的影像检查方法。

Objective To diagnose abdominal aortic dissection aneurysm with color Doppler flow imaging (CDFI).Methods The diamenter of abdominal aorta was measured,the location and extent of separation of intimae in abdominal aorta and its branches were observed,and true lumen was indentified from false lumen by CDFI.Results Separation of intimae was the most reliable criteria for diagnosis.The phenomenon of blood flow separation,artery dilation,intra luminal thrombosis and so on were able to assist its diagnosis.CDFI can well identify true lumen from false lumen and diagnose the rupture of abdominal aortic dissection aneurysm.Conclusions CDFI can well evaluate the involved vessels,and is a reliable modality of imaging examinations.
