Background and purpose: The impact of serum caveolin-1 (Cav-1) on clinical outcomes in patients after mechanical thrombectomy (MT) is unclear. We aimed to investigate the association between serum cav-1 levels and the 3-month functional outcome. Methods: We prospectively enrolled and analyzed patients with an anterior circulation large vessel occlusion who underwent MT. Serum cav-1 concentrations were tested after admission. The primary outcome was a 90-day modified Rankin Scale score of 3–6. Results: Of the 237 recruited patients (mean age, 69.7 ± 12.1 years; 152 male), 131 (55.3%) experienced a 90-day poor outcome. After adjustment for demographic characteristics and other covariates, patients with higher serum Cav-1 levels had a reduced risk of poor outcome at 3 months (Per 1-standard deviation increase; odd ratios [OR], 0.59; 95% confidence interval [CI], 0.39 − 0.89, P = 0.013). Elevated Cav-1 concentrations (Per 1-standard deviation increase; OR, 0.59; 95% CI, 0.40 − 0.88, P = 0.011) were significantly associated with a favorable shift in modified Rankin Scale score distribution. Similar results were confirmed when the Cav-1 levels were analyzed as a categorical variable. Furthermore, the restricted cubic spline showed a linear association between Cav-1 levels and 90-day poor outcome (P = 0.032 for linearity). Conclusions: Increased serum Cav-1 levels were associated with improved prognosis at 3 months in ischemic stroke patients after MT, suggesting that Cav-1 may be a potential prognostic biomarker for ischemic stroke after reperfusion therapy.
