Innovative Application of Point of Care Ultrasound in Assessing Ventriculo-Peritoneal Shunt Patency.
Article in Neurosurgery practice, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
BACKGROUND AND
objectivesCurrent techniques to detect obstruction of ventriculo-peritoneal (VP) shunts are costly, invasive, and time-consuming. This study examines the efficacy of using point-of-care ultrasound (POCUS) to identify shunt nonpatency.
methodsWe conducted a single-center observational cohort study on patients with medium-pressure VP shunts for hydrocephalus. POCUS was used to evaluate shunt patency, and the results were compared with computed tomography/MRI/trans-fontanelle ultrasound evaluations for hydrocephalus.
resultsAmong the 39 patients studied, 17.9% had shunt obstructions. Patients with obstructed shunts, on comparison with patent shunts, had higher optic nerve sheath diameter (ONSD): 4.3 ± 0.2 mm vs 4.1 ± 0.2 mm (
conclusionOur study supports the novel use of POCUS for detecting sonological signs of VP shunt nonfunction with very high sensitivity and NPV. This technique is quick, safe, and cost-effective, making it an excellent option for outpatient surveillance of VP shunt obstruction.
