Case Series: Pericardial gossypibomas detected after cardiovascular surgery: Imaging findings
A 68-year-old male patient who had undergone coronary artery bypass graft surgery 1 month earlier was admitted to our hospital for routine control. Chest radiograph showed folded linear radiopaque sponge markers superposed on the left side of the heart that was not there on the preoperative radiograph []. The patient underwent a second operation, and a retained surgical sponge was removed from the left atrioventricular groove on the site of left circumflex artery anastomosis.
