ABSTRACT

Background: The subdermal single-rod contraceptive implant is used by more than one million women worldwide. In México there are ~600,000 colocated implants. Cases of complex implant localization caused by a deep insertion procedure have been reported.
Clinical cases: Two clinical cases of implant with complex localization are presented. Case 1we present a 21-year-old female. After the insertion procedure during the 12-, 24-, and 36-month revisions, the implant could not be located. Case 2we present a 28-year-old female with subdermal single-rod contraceptive implant co-located in the external side of the left arm, partially palpable on the extreme distal area. Transverse cut of ultrasound showed the extreme distal area of the implant at 6 and 7 cm, respectively, t the site of insertion (scar).
Conclusions: Due to simplicity and accessibility, ultrasound is the selected method for identifying deep nonpalpable implants.
