Nickel hypersensitivity associated with an intratubal microinsert system.

BACKGROUND: Although known nickel hypersensitivity is a contraindication to intratubal microinsert placement in the United States, this case demonstrates that nickel hypersensitivity to intratubal microinserts can occur. CASE: A young woman developed an allergic reaction after placement of intratubal microinserts. Nickel hypersensitivity was confirmed with skin patch testing. The microinserts were removed hysteroscopically, and the patient improved. CONCLUSION: If a patient experiences symptoms of an allergic reaction after hysteroscopic sterilization, referral to an allergy specialist is recommended. If nickel hypersensitivity is confirmed, the microinserts should be removed; this may be performed under hysteroscopic guidance.
