升主动脉

Methods Arterial bypass with prosthesis - graft was carried out in 15 cases: ascending aorta- bilateral axillar arteries and unilateral ICA bypass in 6 cases, ascending aorta - bilateral axillar arteries bypass in 3 cases, ascending aorta - unilateral axillar arteries and unilateral ICA bypass in 5 cases, and in one case of complicated TA combined with abdominal aorta, ascending aorta- bilateral axillar arteries and unilateral ICA bypass were performed, followed by unilateral axilla - femeral bypass.

方法15例重症头臂型大动脉炎患者经胸行人工血管旁路术，升主动脉-双腋动脉、单颈内动脉架桥6例，升主动脉-双腋动脉架桥3例，升主动脉一单腋动脉、单ICA架桥5例，1例合并腹主动脉闭塞的复合型，一期行升主动脉-双腋动脉、单ICA架桥，二期行单侧腋股搭桥术。

The preoperation diameter of ascending aorta was taken as baseline. Patients were divided according to its baseline aortic diameter into diameter0 mm group and diameter≥40 mm group, furthermore, the patients were also divided according to echocardiographic findings into bicuspid aortic valve group and tricuspid aortic valve group.

以术前升主动脉直径为基础值，按基础值的大小分为直径﹤40mm组和直径≥40mm组，并按主动脉瓣形态分为二叶主动脉瓣组和三叶主动脉瓣组。

Considering the underlying wall deficiency and the homodynamic stress, the Robiesek operation should be an optimal choice to those patients with a mild to moderate dilated ascending aorta caused by aortic valve lesion.

由于主动脉壁本身存在病理改变和血液动力学冲击，为防止远期升主动脉进一步瘤变或夹层形成，对以主动脉瓣病变为主的轻、中度主动脉根部扩张采用Robicsek术更为合理。

Ascending aortic diameters were compared between diameter0 mm group and diameter≥40 mm group, BAV group and TAV group, respectively, to clarify ascending aortic diameter change tendency following AVR alone.

按不同的分组对升主动脉直径的大小进行比较，研究主动脉瓣置换术后升主动脉直径的变化趋势。

The aortic diameter change rates were (-0.2±1.4) mm/year and (-0.18±0.98) mm/year in aortic diameter0 mm group and≥40 mm group, respectively. There was no significant difference between the two groups. The ascending aortic diameter change rates were (0.8±1.6) mm/year in BAV group, and (-0.3±1.5) mm/year in TAV group. The ascending aortic diameter of patients in BAV group enlarged continuously following AVR.

在升主动脉直径0mm组和≥40mm组中，升主动脉直径的变化率分别为(-0.2±1.4)mm/年和(-0.18±0.98)mm/年，两组之间无显著性差异；二叶主动脉瓣组和三叶主动脉瓣组升主动脉直径的变化率分别为(0.8±1.6)mm/年和(-0.3±1.5)mm/年，二叶主动脉瓣组病人的升主动脉直径在主动脉瓣置换术后仍继续扩大。

To study the changes in diameter of dilated ascending aorta following aortic valve replacement.

研究主动脉瓣病变合并升主动脉扩张的病人在瓣膜置换术后其升主动脉大小的变化。

OBJECTIVE: To compare the rheological properties of stress relaxation in normal and atherosclerotic animal model of ascending aorta, and to identify the effects of atherosclerosis on the stress relaxation properties of ascending aorta.

目的：比较正常和动脉粥样硬化动物模型升主动脉的应力松弛流变特性，确定动脉粥样硬化对升主动脉应力松弛特性的影响。

To compare ascending aorta creep characteristics of the normal and atherosclerotic animal model to identify the effect of atherosclerosis on ascending aorta creep characteristics.

比较正常和动脉粥样硬化动物模型升主动脉的蠕变特性，确定动脉粥样硬化对升主动脉蠕变特性的影响。

Methods: From December 2002 to June 2006, 30 patients with a moderately dilated ascending aorta [mean diameter,(46.7±3.1)mm] underwent concomitant aortic valve replacement or repairing and reinforced aortoplasty with a well-tailored Dacron vascular graft. Follow-up was obtained on all patients with ultrasonic cardiography or computed tomography scan and was (18.0±10.5) months.

对2002年10月至2006年6月间采用主动脉置换或成形、升主动脉缩小成形、升主和根部背心式人工血管包裹术治疗的30例主动脉瓣病变和升主动脉扩张的临床病例进行回顾性分析和随访，平均随访时间(18±10.5)个月。

At the time of aorta opening in routine cardiac surgeries with ECC,the oxygen flux was changed respectively. Two millilitres blood was taken at the time of pre-operation（T0）,30 min after aorta opening（T1）,6 h (T2),24 h (T3) and 48 h after operation (T4) to measure the levels of serum cTnI were measured through ELISA method.

常规体外循环下进行手术，升主动脉开放时改变各组复灌氧流量，分别于术前（T0）、开放升主动脉后30 min（T1）、术后6 h（T2）、24 h（T3）、48 h（T4）各时间点抽取患者锁骨下静脉血2 ml，采用ELISA酶联免疫法测定血浆cTnI含量。
