This case shows that abdominal and pelvic x-ray examinations may not adequately show a misplaced IUD in a gravid woman, and further workup is necessary after delivery if the IUD is not clearly visible on the initial x-ray films. It also shows that chronic inflammation may develop in the area of a misplaced IUD, producing chronic abdominal pain and complications, even after several years have transpired. Finally, patients may still be at risk for complications after an IUD has been removed because of the dense adhesions that develop due to the chronic inflammatory response elicited by the IUD.
该病例表明，腹部和盆腔X线检查可能无法充分显示妊娠女性体内移位的宫内节育器（IUD），如果在最初的X线片上IUD显示不清晰，则在分娩后需要进一步检查。它还表明，即使几年后，移位的IUD所在区域也可能发生慢性炎症，导致慢性腹痛和并发症。最后，由于IUD引发的慢性炎症反应会形成致密粘连，所以取出IUD后患者仍可能有并发症风险。
