How I do it: Surgical interruption of high-flow dural arteriovenous fistulas at the foramen magnum region.

ABSTRACT:

Background

Dural arteriovenous fistulas (dAVFs) in the foramen magnum region (FMR) are rare entity of dAVFs. There is no established treatment for FMR-dAVFs owing to their rarity and anatomical complexity. Herein, we report cases of high-flow dAVFs located at the posteromedial part of the FMR that were successfully treated by surgical interruption.

Methods

We demonstrated the surgical procedures for the interruption of high-flow FMR-dAVF with representative images and videos. In both cases, endovascular transarterial embolization was performed prior to surgical interruption.

Conclusion

As this type of FMR-dAVF has high-risk clinical features, curative surgical treatment is highly desirable.
