A Computational Framework for Automated Puncture Trajectory Planning in Hemorrhagic Stroke Surgery.
Article in Brain and behavior, 2025. 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
backgroundThe treatment surgery for hemorrhagic stroke typically involves a puncture drainage procedure to remove the hematoma. However, the puncture targets for puncture and the puncture trajectory significantly influence the therapeutic outcome. This study proposes a computational framework integrating artificial intelligence (AI)-driven segmentation, principal component analysis (PCA), and empirical optimization to automate puncture path generation.
methodsA software platform named Puncture Trajectory ToolKits (PTK) was developed using C++/Python with ITK/VTK libraries. Key innovations include hybrid segmentation that combines ResNet-50 deep learning and adaptive thresholding for robust hematoma detection. PCA-based longest axis extraction was enhanced by Laplacian mesh smoothing. Skull quadrant theory and safety corridor modeling were used to avoid critical structures. Five complex clinical cases were used to validate the framework's performance.
resultsThe framework demonstrated high accuracy in puncture trajectory planning, with the optimized L2 path achieving a mean surgeon satisfaction score of 4.4/5 (Likert scale) compared to manual methods. The average angle difference between automatically generated and manually designed paths was 16.36°. These results highlight PTK's potential to enhance the efficiency and safety of robotic-assisted neurosurgery.
conclusionPTK establishes a systematic pipeline for trajectory planning assistance, demonstrating technical superiority over conventional methods. The high acceptance rate among surgeons and improved planning efficiency underscore its clinical applicability. Future integration with robotic systems and validation through clinical trials are warranted.
