急性主动脉夹层是一种高致命性的心血管急症。诊断技术的发展使得在紧急情况下能够更早地识别和更准确地诊断。特别是心血管回声在可疑主动脉夹层患者的初步评估中起着重要作用，主动脉瓣的检测是诊断的关键。Blaivas等人报告了剑突下视图中升主动脉夹层的超声征象，其看起来像梅赛德斯奔驰标志[1]。虽然这是瓣和主动脉瓣的组合形式，但主动脉夹层患者的再夹层偶尔会在主动脉中出现三个管腔，这也可能类似于梅赛德斯奔驰标志（图1）。主动脉夹层带瓣的二维短轴视图可能看起来像Mazda符号（图2）。因此，我建议Mazda符号代表带瓣的主动脉夹层，Mercedes Benz符号代表带双假腔的再夹层主动脉。记住这些汽车公司的标志有助于使用心血管回波检测主动脉夹层。
Acute aortic dissection is a highly lethal cardiovascular emergency. Diagnostic developments have resulted in earlier recognition and more accurate diagnosis in emergency situations. Especially cardiovascular echo plays an important role in the primary evaluation of patients with suspicious aortic dissections, and the detection of a flap in the aorta can be a key to its diagnosis. Blaivas et al. reported on an ultrasonographic sign of dissection of the ascending aorta in the subxiphoid view that looked like a Mercedes Benz symbol [1]. Although this was the combinational form of a flap and aortic valve, the redissection in patients with aortic dissection can occasionally present three lumens in the aorta, which may also resemble the Mercedes Benz symbol (Fig. 1). The two-dimensional short axis view of the primary dissected aorta with a flap may look like the Mazda symbol (Fig. 2). Consequently, I would like to propose that the Mazda symbol represent the primary dissected aorta with a flap and that the Mercedes Benz symbol represent the redissected aorta with double false lumens. Remembering these car company symbols could facilitate detecting aortic dissections using cardiovascular echo.
