Surgical resection of spinal dural arteriovenous fistula with micro-tubular retractors under CT guidance: cases report and literature review.
Article in Frontiers in surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: This case report describes the surgical management of spinal dural arteriovenous fistulas (SDAVFs) using micro-tubular retractors under CT guidance, along with a review and analysis of the relevant literature. Methods: The surgical approach involved the use of micro-tubular retractors for a minimally invasive microsurgical technique, guided by CT imaging to treat two cases of spinal dural arteriovenous fistula (SDAVF). The procedure included intraoperative computed tomography (CT) for precise localization of the fistula and indocyanine green angiography to confirm the position and obliteration of the fistula. Preoperative symptoms and postoperative outcomes were documented. Results: Complete obliteration of the fistula was achieved in both patients through minimally invasive microsurgery via a micro-tubular retractor. Clinical improvement was observed postoperatively, and no complications related to the surgical procedure were noted. Early postoperative follow-up (during hospitalization) demonstrated no recurrence of the fistula or postoperative complications.Traditional open surgery may compromise spinal stability; however, the use of a micro-tubular retractor significantly mitigates this risk. Conclusion: Microsurgery via a micro-tubular retractor under CT guidance is a feasible and effective approach for the surgical treatment of spinal dural arteriovenous fistulas (SDAVFs). This method achieves precise localization and minimizes surgical trauma by reducing damage to muscles, ligaments, and bony structures, thereby shortening postoperative recovery time. However, long-term follow-up and additional cases are needed to further validate the clinical efficacy of this technique.
