It is not uncommon for aortic regurgitation to occur after ascending aortic replacement. There are various causes of the aortic valve insufficiency after ascending aorta replacement. Among them, most common is a reoperation after open repair of Stanford type A acute aortic dissection. Although it is becoming safer to perform reoperative cardiac surgery, the risks of operative mortality and morbidity is still higher than those of non-reoperative cardiac surgeries. In order to improve the mortality and morbidity rate, we should select the best strategies with a thorough preoperative evaluation. Moreover, a careful observation after the operation is required to find the complications, especially the patients who have the risk of aortic valve insufficiency.
升主动脉置换术后发生主动脉瓣反流并不罕见。升主动脉置换术后主动脉瓣关闭不全有多种原因。其中，最常见的是斯坦福A型急性主动脉夹层开放修复术后再次手术。尽管再次心脏手术正变得更加安全，但手术死亡率和发病率的风险仍高于非心脏手术。为了提高死亡率和发病率，我们应通过全面的术前评估选择最佳策略。此外，术后需要仔细观察以发现并发症，尤其是有主动脉瓣关闭不全风险的患者。
