右室切開を用いた大動脈基部再置換術

Incising the Anterior Wall of the Right Ventricular Outflow Tract for Reoperation of the Aortic Root

感染性の左室流出路に対する基部再置換術は成績不良である．その原因は支持組織の脆弱さ，不安定さに加え，周囲組織の癒着のため視野展開が困難で，解剖学的な修復の可否が問われる点があげられる．

A 32-year-old man underwent the 3rd aortic root reoperation with incising the anterior wall of the right ventricular outflow tract. He has been doing well. To this day，aortic root reoperation remains challenging. This difficulty may stem from issues securing a physical space and a clear visual field for surgery, in addition to adhesions around the aortic root. In such complex cases, we incise the anterior wall of the right ventricular outflow tract. We have successfully treated seven patients using this method, demonstrating that it can secure physical space and improve the visual field for surgery.
