Aortoesophageal Fistula Secondary to Placement of an Esophageal Stent: Emergent Treatment with Cyanoacrylate and Endovascular Stent Graft

We report on N-butyl 2-cyanoacrylate embolization and subsequent endovascular stent graft placement for the treatment of an aortoesophageal fistula secondary to placement of an esophageal stent. A 53-year-old man with lung cancer was admitted with massive hematemesis due to the formation of an aortoesophageal fistula 20 days after esophageal stent placement. Injection of N-butyl 2-cyanoacrylate into the aortoesophageal fistula was performed as emergent treatment for this hemodynamically unstable condition, and an endovascular stent graft was subsequently placed via the right femoral artery. The patient was well without hematemesis until he died of pneumonia 45 days later. Cyanoacrylate embolization and subsequent endovascular stent graft placement for the treatment of massive hemorrhage caused by an aortoesophageal fistula is a prompt, effective method and can be an alternative to surgical repair.
