Predictors of prognosis in stroke patients with tandem lesions who undergo emergent stenting

Abstract

Background

The optimal endovascular approach for tandem lesions (extracranial internal carotid artery and intracranial large vessel occlusion) is not clear. Aims: The aim was to evaluate the follow-up results of stroke patients with tandem lesions who underwent emergent stenting of extracranial lesions with antithrombotic therapy combined with intracranial MT

Methods

Outcomes and predictors of poor prognosis and mortality compared with those of good prognosis at 90 days, 1 year, and 2 years were assessed. A modified Rankin scale (mRS) score was used. Symptomatic intracranial hemorrhage (sICH), National Institutes of Health Stroke Scale (NIHSS) scores at admission and at 24 h, successful recanalization, asymptomatic ICH, embolization, malignant infarction, decompression, in-stent restenosis and extracranial complications were also evaluated. The best age cutoff for predicting mortality was analyzed

Results

A total of 71 subjects were included. Using patients with a good prognosis as a reference, the independent variables predicting a poor prognosis were a high 24-h NIHSS score and extracranial complications at all timepoints (3-month, 1-year, and 2-year follow-up). The most appropriate age cutoff for predicting 1-year mortality was 67 years [AUC = 0.802 (95% CI = 0.684–0.920); p < .001]. The age cutoff determined for the first year was correlated with the prediction of mortality in the third month and the second year. No significant association was observed between sICH and the groups

Conclusion

In this study, the 24-h NIHSS score after reperfusion and age were predictors of poor prognosis and mortality in stroke patients with tandem lesions who underwent emergent stenting during thrombectomy.
