Abstract

A single-rod subdermal contraceptive implant is usually located around the insertion site, has been usually known to migrate within less than 2 cm of the insertion site and the true migration over 2 cm has been rarely reported. We report a case of migrated radiopaque subdermal contraceptive implant into lung in a 37-year-old woman. On conducted chest computed tomography, subdermal contraceptive implant was in subsegmental branch in left posterior basal segment of lung. Removal of subdermal contraceptive implant in left posterior basal segment of lung by mini-thoracotomy was performed by a chest surgeon. Complications with insertion and removal of subdermal contraceptive implant are rare in the hands of medical professionals familiar with the techniques and these procedures should only be undertaken by those with relevant training. The migration over 2 cm should not occur if the correct subdermal insertion procedure is followed and carried out by a properly trained individual.

  • Fig. 1 (A) Long bone upper extremity standing anterior posterior lateral X-ray showing a linear opaque structure (arrow) in pulmonary hemi-right field. (B) Non-contrast chest computed tomography showing that the foreign body (arrow) was in left lower lobe (probably in subsegmental pulmonary artery branch in left posterior basal segment).

  • Fig. 2 (A) Mini-thoracotomy was performed by a chest surgeon. Left lower lobe was retracted by lung clamp, then subdermal contraceptive implant (arrow) was exposure. (B) The 4-cm-sized subdermal contraceptive implant was removed.
