Lumen-Apposing Metal Stent Bleeding Risk: Management of Splenic Artery Erosion

Lumen-apposing metal stents (LAMS) have been used for drainage of peripancreatic collections, although they may be associated with complications, including bleeding. We report a case of a 49-year-old male patient who developed hematemesis and syncope three and a half weeks after LAMS placement for peripancreatic collection drainage. A computed tomography scan revealed splenic artery erosion by the distal flange of the stent. Splenic artery embolization was performed before LAMS removal, and splenectomy was required 3 days later. The patient remains asymptomatic after two years of follow-up. This case demonstrates an approach to a rare but potentially fatal complication of LAMS.
