The current technique to correct aneurysms of the ascending aorta with incompetence of the aortic valve or dilatation of the aortic root is the implantation of a valved conduit. In many cases however structurally normal aortic leaflets are resected by this technique and patients are at the risk of complications due to mechanical heart valve prostheses and the necessary anticoagulation respectively. By resuspension of the aortic valve into the aortic prostheses similar to the technique used at implantation of homograft valves, competence of the valve can be restored and the dilatation of the aortic annulus can be prevented or even reduced. Our article describes the successful, valve sparing correction of an acute aortic dissection type A with dilatation of the aortic annulus in a 43 year old patient and in another patient with ascending aortic aneurysm with aortic insufficiency.
目前，对于升主动脉瘤合并主动脉瓣关闭不全或主动脉根部扩张的治疗技术是植入带瓣管道。然而，在许多情况下，采用这种技术会切除结构正常的主动脉瓣叶，患者分别面临机械心脏瓣膜假体和必要抗凝治疗相关并发症的风险。通过将主动脉瓣重新悬吊至主动脉假体中，类似于同种异体瓣膜植入时所采用的技术，可以恢复瓣膜的功能，并预防甚至减轻主动脉瓣环的扩张。我们的文章描述了对一名43岁急性A型主动脉夹层合并主动脉瓣环扩张患者以及另一名升主动脉瘤合并主动脉瓣关闭不全患者成功实施保留瓣膜的矫正手术。
