[Two patients with a non-palpable, subcutaneously implanted contraceptive].
Two women, 33 and 31 years of age, were referred to a surgeon for the removal of a previously implanted hormonal contraceptive after the general practitioner had attempted this without success. However, no foreign body could be detected in either patient by surgery, echography and MRI and by X-ray, echography and MRI, respectively. They were then referred to a gynaecologist. In the first patient, a low level of etonogestrel confirmed that there was no contraceptive in her body. Subcutaneous contraceptives are sometimes implanted incorrectly. If the rod is not palpable at the site of insertion, then the etonogestrel level should be determined first of all. If the hormone level indicates that a rod is indeed present, then echography or MRI may be considered to localise it before resorting to surgical exploration. Many problems can be prevented by proper implantation.
