Evolution in Neurovascular Care: Transitioning from AVM to the Neuro Embolization (NE) Module

The landscape of neurointerventional surgery is shifting toward specialized, data-driven care. Consequently, the NVQI-QOD has evolved the AVM module into the newly expanded Neuro Embolization (NE) Module. This transition reflects a much broader clinical scope. Furthermore, it ensures that providers have the “real-time actionable data” needed to measure device effectiveness.

Why the Change?

Previously, the AVM-centric model was too narrow. It did not capture the full spectrum of procedures performed today. Therefore, we updated the module to track a wider array of pathologies. Specifically, the Neuro Embolization Module now covers:

  • Brain Arteriovenous Malformations (AVMs), including nidal aneurysm treatments.
  • Dural Arteriovenous Fistulas (dAVFs).
  • Chronic Subdural Hematoma (cSDH).
  • Middle Meningeal Artery (MMA) embolizations.
  • Epistaxis and other head or neck embolizations for tumors.

The Clinical Need for Expanded Data

The inclusion of MMA embolization for chronic subdural hematomas is very timely. For instance, high-impact clinical research in the New England Journal of Medicine (such as the EMBOLISE and MAGIC-MT trials) shows its benefits. These studies demonstrate that MMA embolization reduces the recurrence of symptomatic hematomas. As a result, these procedures are becoming a new standard of care.

In addition, the complexity of dAVFs and AVMs requires strict long-term monitoring. Because of this, the NE module requires a minimum 80% follow-up rate. Our ultimate goal is to reach 100% follow-up at one year post-procedure. For certain AVM and dAVF cases, we now recommend extended follow-up for up to five years.

Commitment to Excellence

This update is more than just a name change. Instead, it provides “comparable metrics” to improve patient safety. However, the module remains focused on specific cases. Please note that Cerebral Aneurysm treatments should still be documented in the dedicated Cerebral Aneurysm module. The only exceptions are flow-related nidal aneurysms.
