Nexplanon (etonogestrel) contraceptive implants: reports of device in vasculature and lung

There have been rare reports of Nexplanon implants having reached the lung via the pulmonary artery. An implant that cannot be palpated at its insertion site in the arm should be located as soon as possible and removed at the earliest opportunity. If an implant cannot be located within the arm, perform chest imaging. Correct subdermal insertion reduces the risk of these events.
