Imaging findings
Follow-up contrast-enhanced CT shows a fibrin sheath surrounding a Denver shunt catheter in the brachiocephalic vein and superior vena cava, with large, lobulated thrombi extending into the right atrium and right atrial appendage.
Key takeaways
Indwelling venous catheters, such as Denver shunts, are prone to catheter-associated thrombosis and fibrin sheath formation. This host vascular response can act as a nidus for large thrombi in the right atrium and its appendage, carrying a risk of pulmonary embolism.
