3) annuloplasty
瓣环成形术
1.
Percutaneous mitral valve repair for regurgitation, as a new microinvasive technology, has developed rapidly, and includes two basic methods: edge-to-edge repair and annuloplasty.
为了减轻二尖瓣关闭不全外科手术和体外循环所带来的创伤和风险,基于外科边对边缝合和瓣环成形的手术方式,近年来二尖瓣关闭不全的介入治疗得到了快速发展,包括经二尖瓣边对边修补术和瓣环成形术,前者经穿房间隔途径送入钳夹装置或负压抽吸缝合装置,钳夹或缝合前后瓣边缘,形成双孔二尖瓣,后者经右颈内静脉途径把缩环装置植入冠状静脉窦内,缩短瓣环前后径,以减轻二尖瓣反流。
4) valve constriction
瓣膜环缩术
1.
Objective: To observe and compare short-time and long-time outcome in patients of primary deep venous insufficiency of lower limbs with internal valvuloplasty and valve constriction, to investigate which is the better method of the treatment between internal valvuloplasty and valve constriction.
目的：观察比较应用血管内瓣膜成形术和瓣膜环缩术治疗原发性下肢深静脉瓣膜功能不全病人的近、远期疗效；对血管内瓣膜成形术和瓣膜环缩术的优劣之处进行比较研究，探讨简便、有效的手术方法。
5) Expansive surgical flaps
扩大外科皮瓣
6) widening of the ring
环的扩大
补充资料：主动脉
主动脉
aorta
体循环动脉的主干。由左心室发出，起始部有主动脉瓣，可依次分为升主动脉，主动脉弓和降主动脉。降主动脉又分为胸主动脉和腹主动脉。接受左心室搏出的血液，并发出各级分支将血液运输到全身各组织、器官。当主动脉病变(如主动脉瘤、主动脉瓣狭窄、主动脉破裂等）时可影响全身血液的供应。表现出相应的症状和体征，乃至猝死。
