An unexpected adverse event of endoscopic ultrasonography: acute aortic dissection

Abstract

An 81-year-old man was referred to our department for a thoracic spine tumor. After examination for chronic lower back pain and contrast-enhanced computer tomography (CECT), we suspected thoracic spine invasion of esophageal cancer or a posterior mediastinal tumor. With the patient under conscious sedation, we performed EGD and observed extrinsic compression in the middle part of the esophagus (A). Thereafter, we performed EUS. During observation, after subtle resistance, the patient began to describe pain.
