Abstract
Objective
In patients with large vessel occlusion, successful reperfusion is a predictor of favorable outcome. However, patients with underlying intracranial atherosclerotic disease (ICAD) show higher rates of immediate reocclusion, frequently requiring rescue stenting. We aimed to investigate the safety, efficacy, and outcome of acute stenting in acute stroke patients with underlying ICAD.
Methods
Prospective databases from two centers between 2012 and 2021 were reviewed. Adult patients who underwent ICAD-related acute intracranial stenting, after mechanical thrombectomy (MT) were included. Clinical and procedural data, technical success measured by Modified Thrombolysis in Cerebral Infarction score, periprocedural complications, stent restenosis, and follow up mRS at three months were evaluated.
Results
During a 10-year period, a total of 96 patients with acute stroke and intracranial atherosclerotic steno-occlusive lesions underwent stenting after MT. Mean age was 63 (SD 14) and 54 patients were male (56.3%). Successful reperfusion (TICI ≥ 2b) was achieved in 86 patients (89.6%) following rescue stenting; favorable clinical outcome (mRS < 3) was observed in 32 patients (37.6%). Symptomatic intracranial hemorrhage and mortality were observed in 9.5% and 22.4% of patients, respectively. Multivariate regression yielded older age (OR: 0.477, 95% CI: 0.933–0.999, p=0.046) as an independent negative predictor of favorable functional outcome after acute intracranial stenting.
Conclusion
Our results suggest that acute intracranial stenting is safe and effective as a rescue treatment after MT in acute stroke patients with underlying ICAD. Younger age was found as an independent predictor of good outcome. Nevertheless, ICAD still carries a high mortality and poor functional clinical outcome.
