Objective:

To determine the prognostic significance of post-interventional contrast staining in patients with basilar artery occlusion stroke following endovascular therapy, specifically its impact on clinical outcomes.

Key Findings:
  • 42 patients included, with 18 (42.9%) showing contrast staining on CT.
  • Patients with contrast staining had significantly worse outcomes (median mRS: 6 vs. 2, p < 0.001).
  • Contrast staining was a strong predictor of unfavorable functional outcomes, surpassing other imaging parameters, with a significant volume correlation.
Interpretation:

Post-interventional contrast staining is a significant indicator of poor functional recovery in BAO stroke patients after EVT, highlighting its potential role in predicting clinical outcomes and guiding treatment decisions.

Limitations:
  • Retrospective design may introduce selection bias, potentially affecting the generalizability of the findings.
  • Limited generalizability due to the specific patient population and setting.
Conclusion:

Contrast staining on postinterventional CT is a robust predictor of unfavorable outcomes in BAO stroke patients treated with EVT.
