Antecubital vein approach of retrograde transvenous obliteration using a steerable triaxial system for portosystemic encephalopathy.

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
We report a case of portosystemic encephalopathy treated by retrograde transvenous obliteration (RTO) with an antecubital vein approach using a steerable triaxial system. A 77-year-old female was referred to our department complaining of dizziness and tremor. Laboratory data showed hyperammonemia. Contrast-enhanced CT and 3D-CT reconstruction images demonstrated an inferior mesenteric vein (IMV)-left common iliac vein shunt and a splenorenal shunt. The former was treated as a responsible shunt. The spleen volume was 212 mL, and the liver volume was 757 mL; giving a spleen/liver volume ratio of 0.3. Partial splenic artery embolization (PSE) was employed to control portal venous pressure. The hepatic venous pressure gradient (HVPG) changed from 13.2 to 9.6 mm Hg and the spleen/liver volume ratio improved from 0.3 to 0.2 by PSE. Two months after PSE, RTO with an antecubital vein approach using a steerable triaxial system was performed. HVPG changed to 12.5 mm Hg after RTO. Contrast-enhanced CT and 3D-CT reconstruction images 3 days after the procedure demonstrated the thrombus in the IMV-left common iliac vein shunt. We conclude that the antecubital vein approach using a steerable triaxial system is a feasible and minimally invasive technique in RTO for portosystemic shunts.
