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.

This study supports that (i) cognitive executive deficits depend mostly on lateral prefrontal lesions, (ii) with locations varying according to executive process, and (iii) behavioral executive deficits are mainly due to left ventral striatum lesion in post-aneurysmal damage.

Only seven cases of agnosia for mirror stimuli have been reported, always with an extensive lesion. We report a new case of an agnosia for mirror stimuli due to a circumscribed lesion. An extensive battery of neuropsychological tests and a new experimental procedure to assess visual object mirror and orientation discrimination were assessed 10 days after the onset of clinical symptoms, and 5 years later. The performances of our patient were compared with those of four healthy control subjects matched for age. This test revealed an agnosia for mirror stimuli. Brain imaging showed a small right occipitoparietal hematoma, encompassing the extrastriate cortex adjoining the inferior parietal lobe. This new case suggests that: (i) agnosia for mirror stimuli can persist for 5 years after onset and (ii) the posterior part of the right intraparietal sulcus could be critical in the cognitive process of mirror stimuli discrimination.
