Ultrasound-guided percutaneous ventriculoatrial shunt placement in pediatric hydrocephalus: Surgical outcomes and thrombotic complications.
Article in Northern clinics of Istanbul, 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
objectiveVentriculoatrial shunts (VAS) are increasingly used as a salvage option in pediatric hydrocephalus when ventriculoperitoneal shunts (VPS) fail. Although ultrasound-guided percutaneous techniques facilitate catheter placement and reduce surgical trauma, the incidence and management of thrombotic complications remain insufficiently defined.
methodsWe retrospectively analyzed eight pediatric patients who underwent ultrasound-guided percutaneous VAS placement between January 2019 and December 2024. Demographic characteristics, etiology of hydrocephalus, operative details, and post-operative complications were evaluated, with a particular focus on thrombotic events.
resultsPatients underwent a mean of 3.8±1.3 VPS revisions before VAS placement. Myelomeningocele was the most common etiology (50%). The mean operative time was 75.6±13.9 min, and the mean intraoperative blood loss was 86.25±43.07 mL. Post-operative complications occurred in 3 patients (37.5%), including thrombotic events in 2 patients (25%) and infection in 1 patient (12.5%). One patient required early shunt removal due to thrombus formation with vegetation, whereas another developed late asymptomatic thrombosis requiring intervention. The internal jugular vein was the most commonly used access site.
conclusionUltrasound-guided percutaneous VAS placement is a feasible and minimally invasive alternative in selected pediatric patients. However, thrombotic complications may be more frequent than previously reported and can occur both early and late in the post-operative period. These findings highlight the need for standardized surveillance protocols and further investigation into prophylactic strategies, including antiplatelet therapy.
