Background:
This study aimed to evaluate the efficacy of hybrid surgery combined with the sleeve technique in treating spinal dural arteriovenous fistula (SDAVF).
Methods:
A retrospective analysis was conducted on the clinical data of 16 patients with SDAVF who underwent hybrid surgery between October 2020 and June 2024. Spinal-cord function was quantitatively assessed preoperatively and postoperatively using the modified Aminoff-Logue Scale. Postoperative follow-up was 1-36 months. A decrease in the Aminoff-Logue Scale score indicated functional improvement, whereas an increase indicated deterioration.
Results:
Intraoperative spinal digital subtraction angiography results confirmed the complete disappearance of the fistulas in all the 16 cases. Thirteen patients (81%) exhibited improved spinal-cord function, whereas 3 patients showed no changes.
Conclusions:
Hybrid sleeve-assisted surgery integrates the advantages of endovascular interventional therapy and microsurgery, reducing late recurrence and surgical trauma. Consequently, this combined approach represents a valuable, clinically translatable therapeutic modality for the management of SDAVF.
