Material and methods From Jun,1998 to Dec,2004,178 aortic dissections were treated by stent-grafts, including acute 76 cases and chronic 102 cases,19 cases with Stanford A and 159 cases with Stanford B.

1998年6月至2004年12月，共178例主动脉夹层患者接受腔内修复术治疗。其中急性期76例，慢性期102例。Stanford A型19例，Satnford B型159例。

But there are still some uncertainties about this therapy. There is a close relation between aortic dissections and the pulsatile arterial flow within the aorta.

虽然腔内隔绝术的出现给主动脉夹层的外科治疗带来了革命性的变化，但依然存在诸多未定因素。

Methods: The clinical data of 25 patients with complicated aortic dissections were analysed retrospectively. Results: The patients′ ages ranged from 31-72 years with a mean of 50.2 years.

对25例复杂型主动脉夹层行腔内血管外科治疗患者的临床资料进行回顾性研究。

Objective To evaluate the value of transthoracic echocardiography and transesophageal echocardiography in diagnosing aortic dissections and compare them with ultrafast computed tomography and magnetic resonance imaging.

目的 探讨经胸超声心动图、经食管超声心动图对主动脉夹层的诊断价值，并与磁共振影像、超高速CT等影像诊断进行比较。

These medications reduce the strength and frequency of heartbeats, reducing stress on the wall of the aorta.

这些药物降低强度和频率的心跳，减轻压力上墙的主动脉。

There were 6 simple aortic valve replacements and 14 mitral valve replacements in this group.

20例心脏瓣膜置换，其中单纯主动脉瓣膜置换6例，单纯二尖瓣置换14例。

The presence or absence of mitral annular calcification and aortic stenosis was determined by transthoracic echocardiography.

有无二尖瓣环钙化及主动脉瓣狭窄靠经胸壁超声心动图来确诊。

Valvular heart disease, usually aortic and mitral insufficiency, can complicate a variety of systemic diseases.

瓣膜性心脏病，以主动脉瓣及二尖瓣闭锁不全为最常见，可使各种全身性疾病变得复杂。

Valvular heart disease , usually aortic and mitral insufficiency, can complicate a variety of systemic disease s

瓣膜性心脏病，以主动脉瓣及二尖瓣闭锁不全为最常见，可使各种全身性疾病变得复杂。

Methods ECG findings from 75 cases of excessive volume load of left ventricle were discriminated.QRS amplitude variability was studied from 3 diseases such as mitral and aortic insufficiency and patent ducts arteriosus.

采用75例左室容量负荷过重病因的心电图鉴别，研究二尖瓣关闭不全、主动脉瓣关闭不全及动脉导管未闭等3种疾病的QRS振幅变化特征。
