CTICasesRetained 7-0 Prolene Surgical Suture Needle
Imaging findings
Post-operative chest radiograph following aortic valve replacement reveals a tiny, subtle metallic foreign body in the mediastinum, corresponding to a 7-0 Prolene suture needle. The surgical team successfully identified the needle's presence and exact location on the chest radiograph with the assistance of a reference specimen image provided by the radiology department.
Key takeaways
Radiographic detection of tiny surgical needles (such as 7-0 Prolene needles) can be exceptionally challenging. Providing an intraoperative reference radiograph of the exact needle type being searched for is an effective clinical workflow that aids radiologists in spotting extremely small retained foreign bodies before chest closure or during immediate re-exploration.
