Predictive factors and comparative analysis of surgical vs. endovascular treatment for spinal dural arteriovenous fistulas: a 22-year experience at a neurovascular and spine center.

ABSTRACT:

Background

Spinal dural arteriovenous fistula (SDAVF) is a rare disease with insidious clinical manifestations that can often be overlooked on initial examination. Our aim was to identify predictive factors associated with favorable long-term outcomes and to compare the clinical results between surgical and endovascular treatment.

Methods

A retrospective chart review was conducted of 81 patients with SDAVF who underwent either surgical (n = 70, 86.4 %) or endovascular (n = 11, 13.6 %) treatment at our hospital between 2002 and 2023, with a mean follow-up duration of 22.4 months.

Results

A significantly greater proportion of surgical (S) patients (45/70, 64.3 %) showed improvement in the modified Aminoff and Logue Scale (mALS) between admission and last follow-up compa
