Revascularization Surgery

Background: Internal carotid artery stenosis (ICS) can lead to cognitive impairment as well as ischemic stroke. Although carotid revascularization surgery, such as carotid endarterectomy (CEA) and carotid artery stenting (CAS), can prevent future strokes, the effect of revascularization on cognitive function is controversial. In this study, we examined the resting-state functional connectivity (FC) in ICS patients undergoing revascularization surgery, with a special focus on the Default Mode Network (DMN). Methods: We prospectively enrolled 24 ICS patients, who were expecting the intervention of CEA (14 cases) or CAS (10 cases). Cognitive assessment, including the Mini-Mental State Examination (MMSE), the Frontal Assessement Battery (FAB), and the Japanese version of the Montreal Cognitive Assessment (MoCA-J) and rs-fMRI were administered ≤ 1 week preoperatively and postoperatively at 1 week. For the analysis of FC, a seed was placed in the region associated with DMN. Results: After revascularization surgery, significant improvement in the score of MMSE (27.4 vs 28.4, P = 0.03) and MoCA-J (23.1 vs 25.0, P = 0.0001) was found. As for the analysis of the CAS and CEA groups, the MoCA-J score of the CEA group (24.1 vs 26.1, P = 0.001) and the MMSE score of the CAS group (26.0 vs 28.4, P = 0.01) showed statistically significant improvements. In both CAS and CEA groups, Seed-to-Voxel focusing on DMN revealed increased connectivity between medial prefrontal cortex and precuneus. Conclusion: Both CEA and CAS are associated with an improvement in neurocognitive performance and reorganization of functional connectivity, including DMN.

Abstract Objective To validate the previously derived Canadian TIA Score to stratify subsequent stroke risk in a new cohort of emergency department patients with transient ischaemic attack. Design Prospective cohort study. Setting 13 Canadian emergency departments over five years. Participants 7607 consecutively enrolled adult patients attending the emergency department with transient ischaemic attack or minor stroke. Main outcome measures The primary outcome was subsequent stroke or carotid endarterectomy/carotid artery stenting within seven days. The secondary outcome was subsequent stroke within seven days (with or without carotid endarterectomy/carotid artery stenting). Telephone follow-up used the validated Questionnaire for Verifying Stroke Free Status at seven and 90 days. All outcomes were adjudicated by panels of three stroke experts, blinded to the index emergency department visit. Results Of the 7607 patients, 108 (1.4%) had a subsequent stroke within seven days, 83 (1.1%) had carotid endarterectomy/carotid artery stenting within seven days, and nine had both. The Canadian TIA Score stratified the risk of stroke, carotid endarterectomy/carotid artery stenting, or both within seven days as low (risk ≤0.5%; interval likelihood ratio 0.20, 95% confidence interval 0.09 to 0.44), medium (risk 2.3%; interval likelihood ratio 0.94, 0.85 to 1.04), and high (risk 5.9% interval likelihood ratio 2.56, 2.02 to 3.25) more accurately (area under the curve 0.70, 95% confidence interval 0.66 to 0.73) than did the ABCD2 (0.60, 0.55 to 0.64) or ABCD2i (0.64, 0.59 to 0.68). Results were similar for subsequent stroke regardless of carotid endarterectomy/carotid artery stenting within seven days. Conclusion The Canadian TIA Score stratifies patients’ seven day risk for stroke, with or without carotid endarterectomy/carotid artery stenting, and is now ready for clinical use. Incorporating this validated risk estimate into management plans should improve early decision making at the index emergency visit regarding benefits of hospital admission, timing of investigations, and prioritisation of specialist referral.
