Reperfusion grade and outcomes in the ESCAPE-MeVO Trial

Achieving near-complete reperfusion in medium vessel occlusions (MeVO) is linked to smaller final infarct volumes. However, this did not translate into a statistically significant shift in 90-day functional independence.

Talking Points

Recent interactions between the hosts and their guests.

Reperfusion grade and outcomes in the ESCAPE-MeVO Trial

Q: What are the implications for future trials and clinical practice based on your findings?

The results support pursuing more effective reperfusion techniques and trials with adaptive designs to identify which MEVO patients benefit most, while recognizing that not all patients will experience clear functional gains despite favorable tissue outcomes.

Reperfusion grade and outcomes in the ESCAPE-MeVO Trial

Q: What did your sensitivity analyses reveal about the robustness of the infarct-volume findings and their relation to clinical outcomes?

Most analyses pointed in the same direction—reperfusion improves tissue-level metrics, but statistical significance fluctuated across analyses due to exclusions and sample size, suggesting a real effect that is difficult to detect in this dataset.

Reperfusion grade and outcomes in the ESCAPE-MeVO Trial

Q: Could you explain how the MEVO-expanded TIKI score was used and how reliable and practical you found it to be?

They adapted the TIKI framework by setting the denominator to the initial non-perfused territory seen on the first angiographic run, classifying reperfusion progress (e.g., 30% open = TIKI 2A, 70% open = TIKI 2B, full restoration = TIKI 3), and confirming the approach with core-lab consensus amid anatomical variability.

Reperfusion grade and outcomes in the ESCAPE-MeVO Trial

Q: Perhaps we can start off by hearing from you as to what led you to pursue this particular post-doc analysis of the ESCAPE MEVO Trial. And what was the question you were trying to address?

The goal was to determine whether reperfusion quality, specifically near-complete reperfusion, translates into better outcomes for MEVO patients, by adapting and validating a MEVO-specific TIKI-based score and examining if addressing technical limitations could improve results.

Evaluating socioeconomic influences on aneurysm treatment with the Area Deprivation Index

Q: Were you able to derive enough data to consider the ADI as a reasonable screening tool?

The team believes that proving a relationship between ADI and outcomes is the first step, and while screening potential, broader validation and clinical integration would be the ultimate goal, with further work needed to confirm feasibility in routine practice.
