Background: and Purpose In patients with ischemic stroke and isolated cervical internal carotid artery occlusion (c-ICA-O), endovascular therapy (EVT) can improve cerebral perfusion. To maintain vessel patency, EVT is frequently combined with carotid artery stenting (CAS). We assessed the efficacy and safety of emergent CAS during EVT for isolated c-ICA-O. Methods: This retrospective multinational cohort study (42 centers) included consecutive patients who underwent EVT for isolated c-ICA-O within 24 hours from the time last seen well. Patients who underwent emergent CAS were compared with those who did not. Co-primary outcomes were c-ICA vessel patency and symptomatic intracerebral hemorrhage (sICH) 24 hours post-EVT. Secondary outcomes included any intracerebral hemorrhage (ICH) at 24 hours and disability at 3 months (modified Rankin Scale [mRS] shift). Outcomes were adjusted using inverse probability of treatment weighting. Results: Of 317 patients (mean age, 68.6 years [standard deviation, 12.9]; median National Institutes of Health Stroke Scale 11 [interquartile range, 6–17]; 26.8% female), 219 (69.1%) underwent CAS, whereas 98 (30.9%) did not. At 24 hours, vessel patency was more common after CAS (83.5% vs. 40.7%; adjusted odds ratio [aOR], 9.45; 95% confidence interval [CI], 4.91–18.17); sICH rates did not differ (2.3% vs. 3.1%; aOR, 0.92; 95% CI, 0.18–4.73). Any ICH was more common after CAS (19.3% vs. 9.3%; aOR, 2.50; 95% CI, 1.12–5.60). CAS was not associated with mRS at 3 months (adjusted common odds ratio, 0.98; 95% CI, 0.62–1.56). Conclusions In patients undergoing EVT for isolated c-ICA-O, emergent CAS was technically effective and reasonably safe. More frequent vessel patency in patients who underwent CAS did not translate into improved functional outcome at 3 months.

Background: and Purpose Prolonged electrocardiography (ECG)-monitoring in stroke patients improves the detection of paroxysmal atrial fibrillation (pAF). However, most randomized studies only had short follow-up. We aimed to provide 3-year follow-up data for AF detection and stroke recurrence risk. Methods:
We randomized 402 patients aged ≥60 years with acute ischemic strokes without AF to either enhanced and prolonged monitoring (EPM; 3×10-day Holter-ECG-monitoring) or standard-of-care (≥24 hours ECG-monitoring). The endpoint of the current analysis was AF within 36 months analyzed by intention to treat. Long-term follow-up was performed for 36 months. Results:
Two hundred and seventy-four patients (80%) participated in the extended follow-up (median duration of follow-up was 36 months [interquartile range, 12 to 36]). During the first 6 months, more AF was documented in the EPM arm compared to the control arm (13.5% vs. 5.1%; 95% confidence interval, 2.9% to 14.4%; P=0.004). During months 6 to 36, AF was less detected in the EPM intervention arm than in the control arm (2.0% vs. 7.3%; 95% confidence interval, 0.7% to 9.9%; P=0.028). Overall, the detection rate of AF within 36 months was numerically higher within the EPM group (15.0% vs. 11.1%, P=0.30). Numerically less patients in the EPM arm had recurrent ischemic strokes (5.5% vs. 9.1%, P=0.18), transient ischemic attacks (3.0% vs. 4.5%, P=0.44) or died (4.5% vs. 6.6%, P=0.37). Conclusions
Enhanced and prolonged ECG monitoring increased AF detection during the first six months, but there was significantly more clinical AF during months 6 to 36 observed in the usual-care arm. This suggests that EPM leads to an earlier detection of clinically relevant AF.
