This case involves a male patient in South Dakota with a medical history of high blood pressure, obesity, coronary artery disease and previous stents who presented to the emergency department with complaints of chest pain for which he was evaluated and scheduled for surgery to open up blocked arteries and have a stent placement. As the procedure concluded and the guidewire was retracted, the end of it became detached and remained lodged between the surgical opening and the fat underneath the skin. The treating physician referred the patient to vascular surgery to assess the risk-benefits of leaving this foreign body. After evaluation of the site it was determined that the foreign body posed no risk if left since it was not intravascular. An ultrasound was ordered the following week localizing the retained portion of the catheter to the femoral artery, and was removed the subsequent week, as the patient began to present signs of inflammation and pain. After 5 days, the patient began to suffer from increased pain in his leg.
