Purpose

This review examines the clinical, imaging, procedural, and molecular determinants of futile recanalization to better understand why successful reperfusion does not always result in neurological recovery.

half still couldn't live independently despite the vessel reopening

More results

Futile recanalization highlights the biological limitations of macrovascular reperfusion alone.

We propose a mechanistic framework for futile recanalization centered on the "3 R's" of stroke recovery: No-Reflow, No-Rescue, and No-Regrow.

More results

Understanding the multifactorial nature of futile recanalization is essential to improving endovascular thrombectomy outcomes.

Conclusion

By addressing both macrovascular and microvascular factors, it may be possible to translate angiographic success into meaningful functional recovery.
