How do you decide when to intervene directly on a feeder artery aneurysm of an AVM?

Flow-related peri-nidal aneurysms can occur in a few different scenarios, which play an outsized role in determining management. These aneurysms can be located intra-nidal, or can be remote. They can also be detected through routine imaging, but can also present as having ruptured.

AVM hemorrhage is...

Agree with what's been stated. AVM is the most nuanced and complex neurovascular pathology, in my experience. Ruptured or unruptured presentations typically undergo DSA for detailed classification of the angioarchitecture, which guides a multidisciplinary approach. One of the most important reasons ...

In a ruptured AVM, we treat the feeding artery aneurysm as a priority and emergently. Either surgery or embolization is warranted. I prefer embolization in the hyper-acute setting.

In unruptured AVMs with a feeding artery aneurysm that have angioarchitecture amenable to catheterization, I prefer to ...
