관상동맥우회술 중의 경식도 초음파에 의해 발생한, 심부감염을 동반한 Pyriform Sinus 천공

Transesophageal echocardiography (TEE) is widely used to evaluate the heart function and the result of surgery during a cardiac operation. The incidence of complications associated with TEE is low, yet critical complications such as lower pharyngeal injury and esophageal perforation may happen. We report here on a case of 77-year old male patient who suffered from injury to the pyriform sinus and concurrent deep neck infection after off pump coronary artery bypass surgery and intraoperative TEE.
