CT scans of the lower chest were performed before and after elective uncomplicated endoscopic esophageal variceal sclerotherapy in nine patients. CT findings included (1) esophageal wall thickening, (2) low attenuation within the wall giving the esophagus a laminated appearance, (3) a predominantly low attenuation mediastinal effusion that was often masslike, (4) obliteration of mediastinal fat planes, (5) thickening of the diaphragmatic crura, (6) pleural effusions, and (7) subsegmental atelectasis. No mediastinal or pleural gas was seen. Changes were less severe in patients who had received sclerotherapy several times in the past and in those who were given the least amount of sclerosant. An understanding of the CT changes after clinically uncomplicated esophageal sclerotherapy will aid in the interpretation of scans performed on patients with suspected complications.
对9例患者在择期进行无并发症的内镜下食管静脉曲张硬化治疗前后进行了下胸部CT扫描。CT表现包括：（1）食管壁增厚；（2）壁内低密度，使食管呈分层状外观；（3）纵隔积液以低密度为主，常呈肿块样；（4）纵隔脂肪平面消失；（5）膈脚增厚；（6）胸腔积液；（7）亚段肺不张。未见纵隔或胸腔积气。既往接受过多次硬化治疗的患者以及硬化剂用量最少的患者，其变化较轻。了解临床无并发症的食管硬化治疗后的CT变化，将有助于对疑似并发症患者的扫描结果进行解读。
