Abstract

Background

Percutaneous thoracic duct embolization (TDE) is a safe, effective, and minimally invasive option for treating chylothorax. A recent report demonstrated the feasibility of ultrasound-guided intranodal lymphangiography as an alternative to pedal lymphangiography for visualization of the thoracic duct, promising relative technical ease and decreased procedure time for TDE.

Methods

We report a case of postoperative bilateral chylothorax treated with ultrasound-guided intranodal lymphangiography followed by TDE.

Results

Intranodal lymphangiography resulted in rapid opacification of the abdominal lymphatics, permitting technically successful primary and secondary embolization procedures. Deployment of metallic coils and liquid embolic agents within the thoracic duct produced rapid clinical and radiographic improvement.

Conclusion

Intranodal lymphangiography is a reliable, reproducible, and less technically challenging alternative to pedal lymphangiography. © 2013 Wiley Periodicals, Inc. Head Neck 36: E21–E24, 2014
