BACKGROUND Proximal or "downhill" esophageal varices are a rare complication of superior vena caval (SVC) obstruction. Few reports describe downhill varices in dialysis patients with catheter-related SVC occlusion. METHODS We studied a case of downhill esophageal varices in a dialysis patient from our center and reviewed the published literature on presentation, evaluation and treatment in other dialysis patients (MEDLINE database search). RESULTS Including our current case, we identified eight reports of dialysis patients with downhill varices. All cases were recognized after presentation with gastrointestinal bleeding, in contrast to low reported bleeding rates of downhill varices in non-dialysis patients. Localized edema and superficial venous engorgement (signs of SVC occlusion) were each observed in four of eight patients. The duration of hemodialysis dependence ranged from 2.5 to 23 years, and dialysis access history included multiple central venous catheters when described (seven cases). Central venous imaging by direct, magnetic resonance or computerized tomographic venography documented SVC stenosis in all cases. Management included percutaneous transluminal angioplasty of the SVC with or without stenting in five of eight patients, three of whom developed restenosis during observation. Successful surgical venous bypass was performed in one patient after failed percutaneous venoplasty. Varices were treated with band ligation in four of eight cases without reported complications. CONCLUSIONS Although rare, downhill esophageal varices should be considered in the differential diagnosis of upper gastrointestinal hemorrhage in dialysis patients exposed to central venous catheters. Diagnosis should prompt radiographic evaluation of SVC patency. Treatment requires timely and coordinated care by specialists in endovascular interventions and gastrointestinal endoscopy.
