CTICasesRetained Surgisil Mimicking Gossypiboma Post Median Sternotomy
▶ Watch on YouTube — age-restricted, cannot embed here
Imaging findings
A post median sternotomy CT scan revealed significant mediastinal hemorrhage and air, along with a large, ill-defined soft tissue density around the aortic root, initially suspected to be a retained surgical sponge (gossypiboma).
Key takeaways
Surgisil (oxidized regenerated cellulose hemostat), used to control bleeding and air leaks during cardiac surgery, can appear as a large mediastinal soft tissue mass, mimicking a retained surgical sponge. Unlike gossypibomas, Surgisil does not contain radiopaque markers, necessitating consultation with the surgeon or review of the operative note for confirmation.
