Successful Transhepatic Lymphangiography and Embolization for Chylous Ascites following Right Nephrectomy and Inferior Vena Cava Tumor Thrombectomy.
Article in Interventional radiology (Higashimatsuyama-shi (Japan), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The case was a 71-year-old woman who had right renal cell carcinoma with inferior vena cava invasion. After the nephrectomy, chylous ascites appeared. Despite conservative treatment, chylous ascites persisted. No lymphatic leakage was identified on transpedal lymphoscintigraphy, and retrograde thoracic duct cannulation from the left subclavian vein failed. A chylous pseudoaneurysm was identified on computed tomography and embolized percutaneously; however, chylous ascites persisted. Therefore, we performed transhepatic lymphangiography and embolization before placement of a peritoneovenous shunt, and chylous ascites resolved. Transhepatic lymphatic embolization may represent a valuable treatment option for postoperative chylous ascites. This case suggests that hepatoduodenal lymphatic leakage may occur after nephrectomy involving extensive manipulation of the pancreas head or hepatoduodenal ligament, possibly related to cross-communication between hepatoduodenal and mesenteric lymphatics.
