Quality of life and brain damage after microsurgical clip occlusion or endovascular coil embolization for ruptured anterior communicating artery aneurysms: neuropsychological assessment
Bibliographic record
Abstract
OBJECT: For anterior communicating artery (ACoA) aneurysms, endovascular coil embolization constitutes a safe alternative therapeutic procedure to microsurgical clip occlusion. The authors' aim in this study was to evaluate the quality of life (QOL), cognitive function, and brain structure damage after the treatment of ruptured ACoA aneurysms in a group of patients who underwent microsurgical clipping (36 patients) compared with a reference group who underwent endovascular coiling (14 patients). METHODS: At 14 months posttreatment all patients underwent evaluations by independent observers. These observers evaluated global efficacy, executive functions using a frontal assessment battery of tests (Trail making test, Stroop tasks, dual task of Baddeley, verbal fluency, and Wisconsin Card Sorting test), behavior dysexecutive syndrome (the Inventaire du Syndrome Dysexécutif Comportemental questionnaire [ISDC]), and QOL by using the Reintegration To Normal Living Index. Brain damage was analyzed using MR imaging. RESULTS: In the microsurgical clipping and endovascular coiling groups, the distribution on the modified Rankin Scale (p = 0.19) and mean QOL score (85.4 vs 83.4, respectively) were similar. Moreover, the proportion of executive dysfunctions (19.4 vs 28.6%, respectively) and the mean score on the ISDC questionnaire (8.9 vs 8.5, respectively) were not significant, but verbal memory was more altered in the microsurgical clipping group (p = 0.055). Magnetic resonance imaging revealed that the incidence of local encephalomalacia and the median number of lesions per patient increased significantly in the microsurgical clipping group (p = 0.003). CONCLUSIONS: In the 2 groups, no significant difference was observed regarding QOL, executive functions, and behavior. Despite the significant decrease in verbal memory after microsurgical clipping, the interdisciplinary approach remains a safe and useful strategy.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
