Doppler velocities in patent transjugular intrahepatic portosystemic shunts: an analysis of 10 mm vs. 8 mm shunts.
Review in Abdominal radiology (New York), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeTo determine if ultrasound Doppler velocities within transjugular portosystemic shunts/direct intrahepatic portosystemic shunts (TIPS/DIPS) differ based on the stent diameter (8 mm vs. 10 mm) and report typical flow velocities at defined locations along the stent in patients with a patent TIPS/DIPS on venography.
methodsThis study retrospectively analyzed a cohort of TIPS/DIPS recipients at a large tertiary care hospital from 2017 to 2022. Sixty-nine patient-entries with patent TIPS/DIPS venograms and available intervening Doppler US were identified (8 mm n = 41; men: 70.7%, mean age: 57.5 years [range: 36-75 years]; 10-mm n = 28; men: 50%, mean age: 50.2 years [range: 24-74 years]).
resultsThe mean Doppler velocities were significantly different at the mid-stent (184.7 cm/s in 8 mm stents and 148.9 cm/s in 10 mm stents; p = 0.03, 95% CI 4.1-67.5) and hepatic-venous-end of the TIPS/DIPS (172.4 cm/s in 8 mm stents and 141.3 cm/s in 10 mm stents; p = 0.02, 95% CI 5.2-57.0). The mean Doppler velocities were not significantly different at the portal vein end of the TIPS (140.7 cm/s in 8 mm stents and 146.8 cm/s in 10 mm stents; p = 0.77, 95% CI - 34.6-46.8) or in the main portal vein (46.8 cm/s in 8 mm stents and 53.0 cm/s in 10 mm stents; p = 0.29, 95% CI - 5.4-17.9). Peak velocities occurred at the mid-TIPS location for the majority of patent 8 mm TIPS (n = 22) and at the portal-end of TIPS for the majority of 10 mm TIPS (n = 12).
conclusionNormal Doppler velocities within TIPS/DIPS differ depending on the shunt diameter. These findings demonstrate a need for specific Doppler screening thresholds in assessing TIPS/DIPS stents of differing calibers.
