Analysis of anatomical characteristics of congenital pulmonary airway malformation lesions based on CT images.

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
Objective: The surgical treatment of congenital pulmonary airway malformations (CPAM) remains a subject of debate. This study aimed to deeply analyze the preoperative CT imaging data to explore the anatomical characteristics of CPAM lesions, providing additional information to guide surgical treatment for such conditions. Methods: A retrospective analysis was conducted on the medical records of children with congenital pulmonary airway malformations who underwent surgery between 2020 and 2024 at our hospital. Preoperative CT images were processed using 3D Slicer software to analyze the volume, external boundaries, vascular and airway branching, and resection planes (lung venous branch planes) of the lesions. The primary analysis indicators included lesion volume, the volume ratio of the lesion to the affected lung lobe, and the real airway, artery, and venous branches supplying the lesion, as well as the airway, artery, and venous branches that might be severed during resection. Results: A total of 17 cases and 18 corresponding preoperative CT images were included, with 7 cases using enhanced CT scans. The mean age of the patients was 68.9 ± 38.9 months. Most lesions (72.2%) were located in the lower lung. The average volume of the lesions was 47.5 cm Conclusion: The use of preoperative CT imaging and corresponding image processing software allows for a comprehensive analysis of the anatomical characteristics of congenital pulmonary airway malformation lesions. This may help improve the understanding of CPAM and the effectiveness of lesion resection surgeries.
