Nexplanon is a long-acting 4 cm radio-opaque rod shaped contraceptive device implanted in the subdermal layer of the inner, upper arm. Complications from implantation are uncommon and mostly local and minor, including infection at the implantation site with resulting cellulitis or abscess, hematoma, abnormal scar formation, or local damage to nerves and blood vessels. Intravascular insertion is estimated to be at 13 per million Nexplanon implants, and migration and embolization is a rare complication of this device. We present a case report of a 16 year old female who presented to the pediatric emergency department with subjective dyspnea and an embolized contraceptive device within a subsegmental branch of the left lower lobe pulmonary artery. After discussion with consultants, interventional radiology was able to successful retrieve the device without complication.
