The health care system in Peru treats 15,000 dialysis patients annually. Approximately 45% of patients receive therapy using catheters. The incidence of catheter-induced superior vena cava (SVC) occlusion is increasing along with its associated significant morbidity and vascular access dysfunction. One of the unusual manifestations of this complication is bleeding "downhill" esophageal varices caused by reversal of blood flow through esophageal veins around the obstruction to the right atrium. Herein is presented the case of an 18-year-old woman on hemodialysis complicated by SVC occlusion and bleeding esophageal varices who underwent successful endovascular recanalization of the SVC. Bleeding from "downhill" esophageal varices should be considered in the differential diagnosis of dialysis patients exposed to central venous catheters. Aggressive endovascular treatment of SVC occlusion is recommended to preserve upper extremity access function and prevent bleeding from this complication.
秘鲁的医疗体系每年治疗 15000 名透析患者。大约 45%的患者接受导管治疗。随着导管引起的上腔静脉(SVC)阻塞的发病率增加,其相关的显著发病率和血管通路功能障碍也在增加。这种并发症的一种不常见表现是由于阻塞处右侧心房血流逆转,导致食管静脉“下坡”出血性食管静脉曲张。本文介绍了一例 18 岁女性血液透析患者 SVC 阻塞和出血性食管静脉曲张的病例,该患者成功进行了 SVC 的血管内再通。对于暴露于中心静脉导管的透析患者,应考虑将“下坡”食管静脉曲张出血作为鉴别诊断的一部分。建议积极进行 SVC 阻塞的血管内治疗,以维持上肢通路功能并防止该并发症出血。
