Ultrasound-guided guidewire maneuver to resolve peritoneal drainage catheter obstruction in an infant: A case report.
Article in Radiology case reports, 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
Peritoneal drainage failure is a rare but important complication in pediatric patients, and identifying its underlying cause is crucial for safe and timely management. We report a 7-month-old female infant with trisomy 13 and tetralogy of Fallot who developed respiratory failure secondary to ascites and underwent peritoneal drainage under ultrasound guidance. When drainage subsequently failed, ultrasound revealed a membranous soft-tissue structure-suspected omentum-protruding through a catheter side hole. Conventional maneuvers, including saline flushing and positional changes, were ineffective. Under real-time ultrasound visualization, a guidewire was gently advanced, restoring the membrane to its original position and re-establishing drainage. The catheter was safely removed later the same day without complications. This case illustrates the value of ultrasound for real-time diagnosis and management of catheter obstruction and suggests that a guidewire-based approach may serve as a practical and safe option when standard techniques fail.
