A 54-year-old man with AR due to AAE underwent the replacement of ascending aorta by sparing an aortic valve (David operation). Under cardiopulmonary bypass, the aneurysmal aorta and the all three sinuses of valsalva were excised, leaving 5 mm of arterial wall attached to the aortic valve. The aortic valve was reimplanted inside a Dacron graft (28 mm Hemashield) which was calculated by aortic valve leaflet height as well as from the size of LVOT. The patient has survived the operative procedure and showed uneventful recovery. We believe this new procedure preserving the native aortic valve is useful for preventing from some complications associated with an artificial heart valve and improvement of QOL of patient.
一名因自身免疫性主动脉炎导致主动脉根部扩张的54岁男性接受了保留主动脉瓣的升主动脉置换术（David手术）。在体外循环下，切除了动脉瘤样主动脉及所有三个主动脉窦，在主动脉瓣上保留5毫米的动脉壁。将主动脉瓣重新植入一个涤纶人工血管（28毫米Hemashield）内，该人工血管根据主动脉瓣叶高度以及左心室流出道尺寸计算得出。患者手术成功，恢复顺利。我们认为这种保留自体主动脉瓣的新手术有助于预防一些与人工心脏瓣膜相关的并发症，并改善患者的生活质量。
