A 53-year-old man with osteogenesis imperfecta underwent valve replacement and coronary artery bypass surgery. Unexplained symptoms of dyspnea and fatigue in the late postoperative period prompted further evaluation. Transthoracic echocardiography demonstrated obstruction of the right ventricular outflow tract and pulmonary artery by a mass, with a maximum gradient of 50 mm Hg. Multiplane transesophageal echocardiography revealed that the mediastinal hematoma was more extensive than was suggested by the transthoracic echocardiogram. This finding prompted the decision to resort to a more extensive surgical procedure. Surgical drainage continued until no residual hematoma could be visualized by multiplane transesophageal echocardiography. This case report demonstrates the value of multiplane transesophageal echocardiography in the assessment of mediastinal masses.
一名患有成骨不全症的53岁男性接受了瓣膜置换术和冠状动脉搭桥手术。术后晚期出现不明原因的呼吸困难和疲劳症状，促使进一步评估。经胸超声心动图显示右心室流出道和肺动脉被一个肿块阻塞，最大压差为50毫米汞柱。多平面经食管超声心动图显示纵隔血肿比经胸超声心动图提示的范围更广。这一发现促使决定采用更广泛的手术方法。持续进行手术引流，直到多平面经食管超声心动图无法再看到残留血肿。本病例报告证明了多平面经食管超声心动图在评估纵隔肿块中的价值。
