Recurrent renal cell carcinoma post cryoablation secondary to splenorenal shunt thermal sink treated with venous obliteration and subsequent cryoablation.
Article in Radiology case reports, 2026. 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
Cryoablation is an effective treatment for T1a renal cell carcinoma but is subject to dissipation of ablative energy via adjacent blood vessel perfusion, known as thermal sink, which may reduce efficacy. Reduction of blood flow in structures responsible for thermal sink during ablations can limit this effect. We report a 55-year-old patient with cirrhosis complicated by portal hypertension and a recurrent left renal cell carcinoma after 2 cryoablations secondary to thermal sink from an abutting splenorenal shunt (SRS). He subsequently underwent transjugular intrahepatic portosystemic shunt creation done with SRS obliteration followed by cryoablation without recurrence. This case highlights a rare instance of thermal sink from an external vessel and demonstrates how addressing sources of thermal sink can improve ablation outcomes in select cases.
