Migration of a cutter knife blade into the abdominal aorta following penetrating chest trauma: A case report.

We report a rare case of intravascular migration of a cutter knife blade after penetrating chest trauma. A 40-year-old man presented with lower abdominal pain 3 months after an unreported occupational injury to the left anterior chest wall. Computed tomography scan revealed a plate-like foreign body embedded in the distal abdominal aorta and a localized hematoma adjacent to the cardiac apex. The blade was successfully removed during semi-emergent abdominal aortic replacement. This case highlights the potential for delayed migration of sharp intravascular foreign bodies and the importance of whole body imaging in patients with atypical symptoms after penetrating trauma.
