Objective:
The aim of the study was to assess cognitive performance of patients before to extra-intracranial (EC-IC) bypass surgery for cerebral ischemia and 6 months and 1year post-surgery
Participants and Methods:
Between November 2013 and April 2023 we neuropsychologically evaluated 38 patients demonstrating hemodynamic insufficiency following internal carotid artery (ICA) occlusion. Twentynine of them completed neuropsychological testing before and 6 months after EC-IC bypass and 22 after one year. We compared RBANS Index Scores and Verbal fluency scores before and after intervention. All patients underwent standard preoperative neurological and radiological evaluation.
Results:
We found improvement after EC-IC bypass in the following domains 6 months post-surgery: Total Scale (p = .017) and Verbal Fluency Test (p = .015). We detected improvement one-year after the surgery in the following domains: Language (p= .01), Delayed Memory (p= .002), Total Scale (p< .001), Verbal Fluency (p= .007).
Conclusions:
The majority of patients indicated for EC-IC bypass due to ICA occlusion and hemodynamic insufficiency suffer from significant cognitive decline. Consistent with other research studies we can conclude, that neuropsychological performance can significantly improve in specific domains after EC-IC bypass surgery.
