Esophageal stent dysfunction: unclogging the Red Sea

Self-expandable metal stents (SEMS) have been widely used for the palliation of esophageal malignant dysphagia. Stent-related dysphagia is frequent and should raise the suspicion of stent migration, tumor ingrowth or overgrowth. In addition, bleeding has been reported in nearly 7% of patients. Nonetheless, this is the first case report of a complete stent obstruction by abundant blood clot formation. The authors present a 76-year-old male with severe ischemic heart disease and atrial fibrillation, requiring cardiac resynchronization therapy defibrillator and anticoagulation. After being diagnosed with metastasized squamous cell mid-esophageal cancer, he was proposed for chemotherapy and palliative esophageal stenting.
