Intravascular placement and migration of a colonic stent into the inferior mesenteric vein.

Colonic self-expanding metal stents (SEMSs) are commonly used to treat large bowel obstruction due to gastrointestinal malignancy with great success. While mortality is negligible, morbidity from both early and late complications can be significant. Stent perforation, erosion and migration are the most feared complications. We present the first reported case of wire-associated colon perforation with placement and migration of an SEMS into the inferior mesenteric vein (IMV). A man in his early 60s presented with a large bowel obstruction due to a colorectal mass. He underwent endoscopic colonic SEMS placement for colonic decompression. The stent was later found to be within the IMV, requiring a colon resection and retrieval of the stent.
