U.S. referral center experience removing nonpalpable and difficult contraceptive implants with in-office ultrasonography: a case series.

OBJECTIVE: To assess referral center outcomes with removal of difficult or nonpalpable contraceptive implants using high-frequency point-of-care ultrasonography.

STUDY DESIGN: We present a case series examining patients referred to our specialty center from January 2019 through September 2020 for difficult or nonpalpable implant removal.

RESULTS: Of the 54 referrals, six had palpable implants and 48 required ultrasonography. We localized 46 (96%) implants in-office, including 13 located subfascially; two Implanon® implants could not be localized. We successfully completed 50 (96%) of 52 attempted in-office removals, including 12 (92%) subfascial implants.

CONCLUSION: High-frequency point-of-care ultrasonography can effectively localize nonpalpable contraceptive implants leading to successful in-office removal.
