Clinical utility of vascular proximity metrics on preoperative CT imaging in pediatric retroperitoneal teratoma.
Article in Pediatric surgery international, 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
purposeWe identified quantitative cutoff values for CT-based vascular proximity metrics and evaluated their associations with intraoperative complications and extent of resection.
methodsWe reviewed the records of 20 children who underwent retroperitoneal teratoma resection between 2005 and 2025. Using contrast-enhanced CT, we measured tumor-vessel contact length, counted the number of contacted major vessels, and assigned a vascular deformation score from 0 to 2.
resultsIntraoperative complications occurred in seven patients (35%). The contacted vessel count was significantly higher in patients with complications (p = 0.015), and contact length showed a similar trend (p = 0.056). Receiver operating characteristic analysis demonstrated good discrimination for contacted vessel count (AUC 0.838; cutoff 3) and contact length (AUC 0.769; cutoff 58.8 mm). Complication rates were highest when the contacted vessel count was ≥ 3 and contact length was ≥ 60 mm. Complete resection was achieved in 15 patients (75%), and subtotal resection was associated with a higher vascular deformation score (p = 0.029).
conclusionPreoperative CT-based vascular proximity assessment helped estimate surgical difficulty in pediatric retroperitoneal teratoma. A contacted vessel count ≥ 3 and contact length ≥ 60 mm indicated higher complication risk, whereas a higher vascular deformation score was associated with subtotal resection.
