Direct Percutaneous Retrograde Thoracic Duct Access for Embolization Using a Modified Sheath Technique for the Treatment of Chyloptysis and Plastic Bronchitis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Thoracic duct embolization is an established minimally invasive treatment for thoracic lymphatic disorders refractory to conservative therapy. We report the case of a 58-year-old man with chyloptysis and plastic bronchitis who presented with persistent respiratory symptoms despite conservative management. Intranodal lymphangiography demonstrated opacification of the thoracic duct. However, antegrade access via the cisterna chyli was not feasible because of its challenging location, and retrograde transvenous access was unsuccessful because of ductal tortuosity. Ultrasound demonstrated a dilated upper thoracic duct in the left lower neck, which was accessed percutaneously using a micropuncture set adapted as a modified sheath, followed by successful navigation of the microcatheter into the cisterna chyli. Successful embolization was performed using a mixture of n-butyl cyanoacrylate and ethiodized oil, resulting in immediate symptomatic improvement and resolution of the patient's supplemental oxygen requirement. This case demonstrates that direct percutaneous retrograde thoracic duct access using a modified sheath technique is a feasible alternative when conventional approaches are technically challenging.
