CTICasesCook-Swartz Doppler Flow Monitor
Imaging findings
Chest radiograph and CT show a small, ring-like metallic structure and associated thin wires wrapped around an artery in a vascularized chest wall reconstructive flap.
Key takeaways
The Cook-Swartz Doppler probe is an implantable monitoring device placed around a vascular anastomosis in reconstructive surgery. It allows for continuous monitoring of arterial or venous flow in free tissue flaps, and should not be mistaken for a foreign body or catheter fragment.
