摘要

一名56岁的男性,有慢性血液透析中肾母细胞瘤左肾切除术史,6年前接受了使用自体心包(Ozaki手术)的主动脉瓣新冠切除术,以治疗因双叶主动脉瓣引起的主动脉狭窄(AS)。AS逐渐发展,观察到左心室射血分数下降。因此,我们决定使用机械瓣膜进行再次手术主动脉瓣置换术。术中发现自体心包与瓣环缝合处有严重钙化。然而,瓣膜小叶本身的退化是轻微的。虽然Ozaki手术的中期结果很好,但长期结果仍不清楚。在这种情况下,瓣环严重钙化,降低了小叶的活动性。我们报告了第一例AS进展需要在Ozaki手术后长期再次手术的病例。

A Case of Severe Aortic Stenosis after Aortic Valve Neocuspidization Using Autologous Pericardium (Ozaki Procedure).
A 56-year-old man with a history of left nephrectomy for Wilms’ tumor on chronic hemodialysis underwent aortic valve neocuspidization using autologous pericardium (Ozaki procedure) for aortic stenosis (AS) due to a bicuspid aortic valve 6 years ago. The AS gradually progressed and a decrease in the left ventricular ejection fraction was observed. Because of this, we decided to perform reoperative aortic valve replacement using a mechanical valve. Intraoperative findings showed severe calcification at the site where the autologous pericardium was sutured to the annulus. However, the degeneration of the valve leaflets themselves was mild. While excellent mid-term results have been reported for the Ozaki procedure, the long-term results are still unclear. In this case, the annulus was severely calcified, which reduced the mobility of the leaflet. We report the first case of AS progression requiring reoperation in the long-term period after the Ozaki procedure.
