Oesophageal varices usually develop in the setting of portal hypertension secondary to chronic liver disease. However, superior vena cava (SVC) obstruction can result in 'downhill' varices forming in the upper oesophagus. A case of torrential upper gastrointestinal bleeding from SVC obstruction due to chronic central venous access for home total parenteral nutrition is described. It is suggested that in patients presenting with gastrointestinal bleeding in the setting of SVC obstruction, 'downhill' varices should be suspected. The current literature is discussed regarding management of such varices. It is recommended that endoscopic variceal surveillance be carried out in patients with known SVC obstruction.
食管静脉曲张通常在慢性肝病继发门静脉高压的情况下出现。然而,上腔静脉(SVC)梗阻可导致上食管形成“下行性”静脉曲张。本文描述了一例因长期家庭肠外营养的中心静脉置管导致SVC梗阻而引起的上消化道大出血病例。建议对于出现SVC梗阻且伴有胃肠道出血的患者,应怀疑存在“下行性”静脉曲张。本文讨论了当前关于此类静脉曲张治疗的文献。建议对已知存在SVC梗阻的患者进行内镜下静脉曲张监测。
