实时超声图象是一种有用的、无创伤性的诊断胸—腹部夹层主动脉瘤的方法,用以下图象可彻底地研究整个主动脉:1.近端升主动脉段和降主动脉的胸骨左旁长轴和短轴图象;2.升主动脉的右胸第二肋间隙的长轴和短轴图象;3.主动脉弓的胸骨上凹的长轴和短轴图象。4.远端降主动脉和腹主动脉的肋下长轴和短轴图象。5.其它的辅助图象:双锁骨上凹图象和降主动脉靠近背部(脊柱的左侧)图象。马凡氏综合征是一种全身性结缔组织病,是以常染色体异常为特征的遗传性疾病。成人患者中有30—60％的病人出现心血管系统的改变。临床主要病变有主动脉环、华氏窦和升主动脉的扩
Real-time ultrasound imaging is a useful and noninvasive method of diagnosing thoracic-abdominal dissection of the aortic aneurysm. The entire aorta can be thoroughly investigated using the following images: 1. The proximal ascending aorta segment and the descending aorta Long axis and short axis images of the left side of the sternum; 2. Long and short axis images of the second intercostal space of the right thorax of the ascending aorta; 3. Long and short axis images of the concave upper sternum of the aortic arch. 4. Long-axis and short-axis images of the distal inferior aorta and abdominal aorta. 5. Other ancillary images: double supraclavicular sulcus and descending aorta near the back (left side of the spine). Marfan syndrome is a systemic connective tissue disease, is characterized by autosomal abnormalities genetic disease. 30-60% of adult patients have cardiovascular changes.
