Unintended pregnancy after long-term Essure microinserts placement.

A case of uterine perforation by an Essure microinserts placed in proximity to the tubal ostia mimicking proper microinsert placement and bilateral tubal occlusion on imaging techniques is presented. The presence of Essure microinserts did not interfere with implantation and pregnancy, and in this case, no adjacent intraabdominal tissue damage was caused by the misplaced device, which was finally removed almost 3 years after insertion.
