Abstract：
A woman in her 20s was referred to a tertiary hospital emergency department for management of a migrating Implanon NXT. The Implanon was inserted 1 week prior by the patient\'s general practitioner who was unable to palpate the Implanon after insertion and hence, ordered an ultrasound scan which showed an actively migrating Implanon in the left basilic vein. She had mild chest pain, and her physical examination, ECG and blood tests were unremarkable. A CT chest showed a 31 mm foreign body within the right lower lobar artery. The foreign body was removed by interventional radiology by accessing the right internal jugular vein under ultrasound guidance and inserting a 6 FR pig catheter into the pulmonary trunk. The position was confirmed with angiogram and the foreign body was removed using a goose neck snare. The patient was discharged the same day with no complications, and fell pregnant a few months afterwards.
