Computed tomography of the chest following endoscopic injection sclerotherapy for esophageal varices was performed in 17 procedures in 13 patients. CT scans were obtained before and within 48 hours after the procedure. CT findings included: esophageal wall thickening; a low-attenuating lesion within the wall of the esophagus with varying appearances, either laminated, localized, or inhomogeneous; a mediastinal lesion; pleural effusion; and various types of pulmonary changes such as atelectasis, pleural-based lesions, dilatation of peripheral pulmonary vessels, and nodular lesions. However, on follow-up CT they had regressed or disappeared. The changes in the mediastinum and pleural space might be caused by direct extension of inflammation from the esophagus, but those in the lungs, especially dilatation of peripheral vessels, may be caused by the sclerosing agent passing to the pulmonary vessels.
对13例患者的17次内镜下食管静脉曲张硬化治疗术后进行了胸部计算机断层扫描。在治疗前及治疗后48小时内进行了CT扫描。CT表现包括：食管壁增厚；食管壁内出现低密度病变，形态各异，可为分层状、局限性或不均匀性；纵隔病变；胸腔积液；以及各种类型的肺部改变，如肺不张、胸膜下病变、外周肺血管扩张和结节状病变。然而，在随访CT检查时，这些病变已消退或消失。纵隔和胸腔的改变可能是由食管炎症直接蔓延所致，但肺部的改变，尤其是外周血管扩张，可能是硬化剂进入肺血管引起的。
