Abstract: | We report a case of life-threatening esophageal hemorrhage after metal stent implantation successfully treated by arterial
embolization. An 85-year-old woman was admitted in shock secondary to massive hematemesis and melena. Recent medical history
revealed esophageal cancer treated 8 weeks previously by endoesophageal radiotherapy (40 Gy) and endoscopic placement of a
covered Wallstent prosthesis. Selective arteriography of the fifth posterior right intercostal artery showed massive contrast
extravasation in the esophagus. Embolization was performed with 150–250-μm polyvinyl alcohol particles. Follow-up at 5 months
was uneventful. Arteriography and embolization are advised when severe hemorrhage occurs after esophageal implantation of
metal stents. |
