Direct trans-cervical endolymphatic thoracic duct stent-graft for plastic bronchitis.

Plastic bronchitis is a poorly understood and uncommon diagnosis, arising from multiple etiologies. Traditional treatment consists of steroids and vasodilators, with thoracic duct embolization emerging as a new procedural therapy. Herein, abnormal lymphatic vessels were noted on lymphangiography in an adult patient with debilitating plastic bronchitis, but anterograde lymphatic access was not feasible due to the patient's morbid obesity and non-visualization of retroperitoneal lymphatics. After trans-venous thoracic duct access could not be established, direct trans-cervical thoracic duct access was performed. A thoracic duct stent-graft was placed, excluding the abnormal bronchial lymphatics and maintaining physiologic anterograde flow through the central lymphatics. At three-month follow-up, the patient's condition had resolved. Copyright by International Society of Lymphology.
