CTICasesRetained Suction Catheter Tip (Intraoperative Foreign Body)
▶ Watch on YouTube — age-restricted, cannot embed here
Imaging findings
An intraoperative chest radiograph, performed to locate a missing suction catheter tip during an open-chest procedure, initially appeared negative due to overlying structures. Subsequent post-operative imaging, including cross-table lateral views and a CT scan, revealed the suction catheter tip lodged in the aortopulmonary window.
Key takeaways
Intraoperative radiographs, especially single-view studies with overlying equipment, can fail to detect retained foreign bodies. Multiple radiographic views and cross-sectional imaging may be necessary to confidently exclude retained surgical items.
