Pregnancy After Microinsert Sterilization With Tubal Occlusion Confirmed by Hysterosalpingogram

BACKGROUND: Introduced to the U.S. market in late 2002 as a permanent method of contraception, a microinsert device is placed hysteroscopically into the fallopian tubes, not requiring incisions or general anesthesia. This report describes a case of pregnancy more than 6 months after a hysterosalpingogram (HSG) confirming bilateral occlusion after microinsert sterilization. CASE: A 30-year-old gravida 1 para 1 woman desired permanent sterilization. The patient underwent microinsert device placement and 6 months later had an HSG that confirmed bilateral tubal occlusion. More than 6 months after the confirmatory HSG, the patient became pregnant and delivered a term infant by cesarean birth. Cornual perforation was noted at surgery. CONCLUSION: This case illustrates pregnancy after microinsertion sterilization and an HSG confirming bilateral tubal occlusion, despite perforation. A microinsert device continues to be a viable option for sterilization.
