Intrapulmonary Migration of Implanon Requiring Thoracotomy and Pneumonotomy
This paper reports a rare case of a 27-year-old woman who underwent a successful thoracotomy and pneumonotomy to remove an Implanon contraceptive implant that had migrated from her arm into her left lower lung lobe, underscoring the critical need for early imaging and surgical intervention when such devices become non-palpable.

Most people know that birth control pills or injections require daily or monthly attention, but there is a different kind of contraception that works quietly for years without any daily effort from the user. This method involves a tiny, flexible rod, about the size of a matchstick, that a doctor inserts just under the skin of the upper arm. Once in place, it slowly releases a hormone that prevents pregnancy for three to five years. It is designed to be a safe, long-term solution, and for the vast majority of women, it stays exactly where it was put. However, in extremely rare instances, this small device can slip out of its intended spot. Instead of staying in the arm, it can enter a blood vessel, travel through the heart, and get lodged in the lungs. While this sounds like a scene from a science fiction movie, it is a documented medical reality that requires careful attention from doctors to ensure the device is found and removed safely.
A team of surgeons in Ethiopia recently shared the story of a young woman who experienced this rare complication. The patient, a twenty-seven-year-old woman, had the rod inserted into her left arm three years earlier. When she returned to her local clinic to have it removed, the doctors could not feel it under her skin. They tried to find it with their hands and even made a small cut to look, but the device was gone from the arm. This failure to locate the object was the first sign that something unusual had happened. The woman was referred to a larger hospital where doctors suspected the rod might have traveled far from its original home. They performed a detailed scan of her chest, which revealed the truth: the four-centimeter rod had migrated through her bloodstream and was now stuck deep inside the tissue of her left lung.
The medical team faced a difficult decision about how to retrieve the object. They considered waiting to see if it would cause problems, but they worried that leaving it there could damage the delicate blood vessels or lung tissue over time. They also considered a less invasive method where a doctor would try to pull the rod out through a vein in the leg, but the surgeons determined this was not possible in their specific situation because the rod had been there for too long and had likely become stuck firmly in the lung tissue. The only safe option was to perform open surgery. The patient was put to sleep, and the surgeons made an incision along her left side to access her chest cavity. They carefully opened the lung itself, located the rod by feeling for it with their fingers, and gently cut the tissue just enough to pull the device out without removing any part of the lung.
The surgery was successful, and the rod was removed completely intact. The patient recovered quickly, with her lung healing well and no further complications arising. This case serves as a clear reminder of what happens when a medical device moves to an unexpected place. It highlights the importance of knowing exactly where the device is before trying to remove it. If a doctor cannot feel the rod in the arm, they must use imaging tools like scans to find it rather than making blind cuts that could cause injury. The story also shows that even when a foreign object ends up deep inside a vital organ like the lung, skilled surgeons can remove it safely and allow the patient to return to a normal, healthy life.
