Squamous cell carcinoma-induced gastric conduit-thoracic aorta fistula presenting with massive hematemesis 4 years after radical esophagectomy: a CARE guidelines-compliant case report

In late post-esophagectomy patients presenting with massive upper gastrointestinal bleeding, high clinical suspicion for arterioenteric fistula is warranted. Computed tomography angiography and DSA should precede endoscopy in hemodynamically unstable patients. TEVAR offers a minimally invasive, rapid means of hemorrhage control, serving as a critical bridge to definitive cancer management.
