Authors report a 61-year-old female with an aortic aneurysm at the distal end of the Hufnagel ball valve which was implanted surgically for the treatment of aortic insufficiency 23 years previously. The Hufnagel ball valve has been working well for the past 23 years, but the aneurysm was found enlarging in size, therefore the replacement of aneurysm with a 20 mm dacron graft was performed following removal of the well-working Hufnagel ball valve. There were 151 cases with Hufnagel ball valve implantation in the literature and at least 7 cases of them were reported in Japan. Among them, the majority survived only several years after surgery and the cases with long-term survival were very few in number. Our case is unique, because the valve in this case has worked well for 23 years.
作者报告了一名61岁女性，其在23年前为治疗主动脉瓣关闭不全而手术植入的胡夫纳格尔球瓣远端存在主动脉瘤。在过去的23年里，胡夫纳格尔球瓣一直运作良好，但发现动脉瘤尺寸在增大，因此在移除功能良好的胡夫纳格尔球瓣后，用20毫米的涤纶补片进行了动脉瘤置换。文献中有151例胡夫纳格尔球瓣植入病例，其中至少7例在日本有报道。在这些病例中，大多数在术后仅存活数年，长期存活的病例数量极少。我们的病例很独特，因为该病例中的瓣膜已经正常工作了23年。
