Transesophageal echocardiography (TEE) was used for the serial observation of a postoperative perivalvular abscess of a prosthetic aortic valve in a 65-year-old man who underwent aortic valve replacement for aortic regurgitation. Five months later, TEE revealed an aortic ring abscess. Ascending aortic grafting (Bentall method) and translocation of the aortic prosthetic valve were conducted for progressive mechanical valve dysfunction. Postoperative TEE showed flow between the left ventricular outflow tract and the abscess, which was unrestricted 1 month later. Associated clinical improvement suggested that washout of the abscess was a critical factor. This case illustrates the usefulness of TEE for examining postoperative aortic ring abscess.
经食管超声心动图（TEE）用于对一名65岁男性人工主动脉瓣术后瓣周脓肿进行系列观察，该患者因主动脉瓣反流接受了主动脉瓣置换术。五个月后，TEE显示主动脉环脓肿。因进行性机械瓣膜功能障碍，实施了升主动脉移植术（Bentall法）和主动脉人工瓣膜移位术。术后TEE显示左心室流出道与脓肿之间存在血流，1个月后血流不受限。相关的临床改善表明脓肿的清除是一个关键因素。该病例说明了TEE在检查术后主动脉环脓肿方面的实用性。
