Difficult Removal of Subdermal Contraceptive Implants: a Multidisciplinary Approach Involving a Peripheral Nerve Expert

Objectives: We aim to describe our experiences and identify patients who may benefit from referral to a peripheral nerve surgeon for removal of contraceptive subdermal implants in which neurovascular injury may occur, and describe a treatment pathway for optimal care.

Study Design: We reviewed the charts of 22 patients who were referred to the Division of Family Planning for difficult removal of etonogestrel contraceptive implants between January 1, 2014, and April, 1 2016. Of these, five were referred to a peripheral nerve surgeon due to pain or location of the implant. We evaluated and described these cases and, from our findings, developed recommendations for care in a multidisciplinary team approach.

Results: Two patients reported pain, including one with four previous failed removal attempts. In the two patients with pain, the implants were adherent to a sensory nerve. In another, the implant was within the biceps muscle and difficult to locate. In all cases, ultrasound imaging, general anesthesia and a wide exposure allowed for safe removal and good outcomes. Our multidisciplinary care approach has elucidated important referral and technical considerations that improve patient care and safety.

Conclusion: When necessary, multidisciplinary care with a Family Planning expert and possibly a peripheral nerve surgeon may be beneficial in safely removing etonogestrel contraceptive implants that would be difficult or risky to remove in an ambulatory setting.
