Overview

Observational study evaluates treatment strategies for acute stroke with PCA occlusion, suggesting limited EVT benefits.

Key Points

  • To assess the impact of endovascular therapy on functional outcomes in acute stroke patients with PCA occlusion.
  • Multicenter international observational study of consecutive acute stroke patients with isolated PCA occlusion.
  • Patients received either best medical management alone or combined with EVT within 6 hours of symptom onset.
  • Primary outcome measured was good functional outcome using modified Rankin Scale at 3 months.
  • 295 patients included: 69 received BMM + EVT, 226 received BMM alone.
  • EVT was not associated with good functional outcome (PSOW-OR 0.99, 95% CI 0.54–1.83; P = 0.97).
  • Perfusion mismatch volume did not influence the association between EVT and good functional outcome (Pinteraction = 0.42).
