Endovascular treatment of diffuse mandibular arteriovenous malformation: a case report and literature review.
Article in Frontiers in cardiovascular medicine, 2025. 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
Background: Arteriovenous malformations (AVMs) are rare congenital vascular anomalies involving high-flow shunting between arteries and veins. Intraosseous AVMs of the mandible are particularly uncommon and present substantial diagnostic and therapeutic challenges. Because even minor trauma or dental procedures may trigger severe hemorrhage, early recognition and appropriate management are essential. Case presentation: We describe a 33-year-old woman with a long-standing vascular lesion of the right mandible who developed uncontrolled oral bleeding after tooth extraction. Imaging confirmed a diffuse intraosseous AVM. After multiple unsuccessful treatments elsewhere, she underwent endovascular therapy consisting of super-selective arterial and venous access, coil embolization, and sclerotherapy with absolute ethanol and polidocanol foam. The procedure resulted in complete occlusion of the lesion without complications. Follow-up at 4 days, 6 months, and 1 year showed no recurrence. Conclusion: Mandibular AVMs are complex lesions that carry a significant risk of life-threatening hemorrhage. This case demonstrates that combined endovascular embolization and sclerotherapy can provide effective and durable control. Accurate diagnosis, timely intervention, and continued follow-up are essential to achieving favorable outcomes for this rare condition.
