Background:

Arterial catheterization of cerebral arteriovenous malformations (AVMs) can be challenging due to recurrent feeders.
Recurrent feeder anatomy often impedes successful microcatheter navigation and embolization.

Observation:

A compliant balloon was used to support microcatheter navigation in eight patients with AVMs and recurrent feeders.
The balloon was inflated in the parent artery to stabilize the microcatheter during advancement.

Findings:

Distal access to the AVM nidus was achieved in all eight patients using the balloon-assisted technique.
Anatomical cure was documented in 75% of cases, with no reported arterial perforations or thromboembolic events.

Implications:

This compliant balloon technique offers a straightforward and effective method for navigating challenging AVMs with recurrent feeders.
The technique may improve AVM embolization outcomes by simplifying microcatheter navigation and reducing procedural complications.
