升主动脉

The present study demonstrated that the distensibility of the ascending aorta was reduced in patients with aortic dissection as compared with that of both hypertensive patients and normal subjects.

本研究试图通过与年龄和性别匹配的正常人和高血压患者进行对比，用无创的超声技术，对主动脉夹层的升主动脉弹性特征进行实时研究。

In the current study it is difficult to be certain that the decreased aortic distensibility in aortic dissection were due to structural changes of the aortic wall, or simply reflected dilated aortic dimension and aortic valve regurgitation. Further study is necessary to elucidate the underlying mechanisms for this abnormalities.

本研究用无创的超声技术证明主动脉夹层之升主动脉扩张性明显降低，这对主动脉夹层病因学的进一步深入研究无疑具有重要意义；但其降低是由于血管本身结构异常所致还是继发于血管内径的扩张尚有待进一步深入研究。

It is limited, however, in visualising the distal ascending, transverse, and descending aortas in a substantial number of patients.

但是，对相当一部分患者而言，它对诊断升主动脉远端、主动脉弓、降主动脉处的病灶作用十分有限。

Isthmal narrowing and enlargement of the ascending and descending aorta are demonstrated.

一晚期妊娠胎儿的主动脉缩窄合并充血性心力衰竭，可见环形狭窄和升主动脉和降主动脉增宽。

METHODS: The ascending aorta, abdominal aorta, and renal artery were harvested within 1 hour of death.

死后1 h之内解剖取死者出升主动脉、腹主动脉、肾动脉，将标本沿纵向切成长25 mm的试样共26个。

Computed tomography showed a type A aortic IMH from the ascending aorta to the descending aorta.

电脑断层扫描显示由升主动脉至降主动脉皆有主动脉壁內血肿。

Its incidence of atheroscerosis was 100% in some liable positions such as aortic sac and ascending aorta at 8~10 months.Most of the pathological changes were in fatty streaks.

该品系8-10月龄动脉硬化在好发部位，如主动脉窦、升主动脉的阳性检出率为100%，主要是处于脂斑和脂纹期的病变。

Pulsed Doppler echocardiograph was used to test separately blood flow velocity wave of ascending aorta arcus, aorta and abdominal aorta in of 17 patients with aortic insufficiency with nonliner factor and results compared with those of 15 normal subjects of the same ages. The purpose was to disclose the regulation of blood flow waveform distortion in arterial system and the existance of shock wave.

应用超声多普勒对存在非线性因素的17名主动脉瓣关闭不全患者的升主动脉、主动脉弓以及腹主动脉进行分段逐点测试血流速度波，并和年龄相匹配的15名健康受试者为对照进行前瞻性探究，以探索人体动脉系统中血流波形畸变的规律及激波的存在。

These include: the pre-VAD insertion examination of the heart and largevessels to exclude significant aortic regurgitation, tricuspidregurgitation, mitral stenosis, patent foramen ovale, or othercardiac abnormality that could lead to right-to-left shunt afterleft VAD placement, intracardiac thrombi, ventricular scars,pulmonic regurgitation, pulmonary hypertension, pulmonary embolism,and atherosclerotic disease in the ascending aorta; and to assessright ventricular function; and the post-VAD insertion examinationof the device and reassessment of the heart and large vessels.

这些包括：（1） VAD 植入前心脏和大血管的检查以排除明显的主动脉反流、三尖瓣反流、二尖瓣狭窄、卵圆孔未闭或者可能引起左 VAD 植入后右向左分流的其他心脏异常，心内血栓、心室疤痕、肺动脉反流、肺动脉高压、肺栓塞和升主动脉粥样硬化疾病；并且评估右室功能；（2） VAD 植入后检查设备及再评估心脏和大血管。
