Grading scale based on arcuate fasciculus segmentation to predict postoperative language outcomes of brain arteriovenous malformations.

The involvement of the trunk of the AF between Broca's area and the inferior parietal lobule, a nidus supplied by the AChA, older patient age and history of LD were associated with long-term postoperative LD. The grading system combining these factors demonstrated favourable predictive accuracy for long-term language outcomes.
