    We would like to thank Su X, et al for their interest and their remarks1 on our research. We analyzed the natural history, angiographic characteristics and treatment outcomes of anterior cranial fossa dural arteriovenous fistulas (ACF-dAVFs) during a period of 27 years.2 This analysis determined that microsurgery achieved ACF-dAVF closure in all cases (35/35), while endovascular therapy (EVT) achieved closure in 53% (9/17) of cases.

    As we acknowledged in the limitations of our study, there has been a robust improvement in endovascular techniques in the last two decades and the inclusion of data acquired within 27 years may not reflect the most up to date EVT. The introduction of new liquid embolics, more navigable microcatheters and improved imaging quality allows the endovascular treatment of …
