主动脉夹层的超声表现

Ultrasonographic features of aortic dissection

目的回顾以往病例，加深对主动脉夹层的认识，提高超声工作者对主动脉夹层的诊断水平。方法使用Vivid-7超声诊断仪及LOGIQE便携式超声仪经胸、经腹、经胸骨上窝探查。结果4例拟诊患者中确诊3例，均有主动脉增宽，可见内膜片样回声；2例可见真腔明亮与假腔暗淡的血流，1例可见撕裂的内膜1：7，2例伴有冠状动脉损伤造成的心肌梗死，1例伴有肠系膜动脉损伤。结论超声对主动脉夹层有很高的诊断价值，关键是工作人员对主动脉夹层要有认识、有警惕，特别是对怀疑心肌梗死的年轻患者，要考虑本病的可能性。

Objective To deepen the understanding of aortic dissection and improve the diagno- sis level of ultrasonic doctors of aortic dissection, with a review of the previous cases. Methods Use the Vivid-7 ultrasonic diagnostic apparatus and LOGIQ E portable ultrasound system on the chest, abdomen and the suprasternal fossa to probe. Results Four cases of diagnosed clinical patients, 3 cases confirmed, all had aortic broadening, intimal flap sample echo inside visible; Two eases of true lumen bright visible in blood flow to the false lumen dim, 1 case of visible tear lining of the mouth, 2 eases of coronary myocardial infarction caused by injury, 1 case of mesenteric artery damage. Conclusions Ultrasound has a high value in the diagnosis of aortic dissection, and the personnel＇ s awareness and vigilance is the key. When facing young patients with suspected myocardial infarction, the possibility of this disease should be taken into consideration.
