Carotid stenting is a widely employed procedure for carotid artery stenosis therapy, a condition that can lead to stroke. Embolic protection devices (EPDs) usage during carotid stenting has been shown to decrease periprocedural stroke and neurocognitive deficits risk. However, the use of EPDs can also lead to technical complications, such as device-related issues, access site complications, and vascular injury. Furthermore, the cognitive outcomes following carotid stenting with and without EPDs are still not well understood. The purpose of this work was to analyze protection device usage impact on procedural related complication rate and cognitive function. Results: Cognitive assessment was done on 13 patients only before and after an intervention. (2 patients did not come for follow up). A substantial post-intervention development was observed in PALT score (p value=0.01), Trail A (p value=0.01), Trail B (p value˂0.001) and BVRT (p value=0.03). Cognitive assessment was done on 12 patients only before and after the intervention. (3 patients did not come for follow up). A substantial post-intervention development in scores of PALT (p value=0.01), Trail A (p value=0.01), Trail B (p value=0.01) and BVRT (p value=0.02). No statistically substantial change was seen among both groups regarding the post-intervention improvement in PALT scores (p value=0.37), Trail A (p value=0.94), Trail B (p value=0.11) and BVRT (p value= 0.95). Conclusions: Using protection device in carotid stenting doesn’t have a statistically significant impact in improving cognitive function or reducing the possibility of development of new ischemic lesions.
