Resolution of a femoral arteriovenous fistula secondary to chronic Iliac vein occlusion after stenting: a case report.
Article in BMC 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
backgroundAcquired femoral arteriovenous fistula (FAVF) secondary to chronic iliac vein occlusion is rare and often underdiagnosed. The optimal management remains controversial. CASE PRESENTATION: An 80-year-old woman presented with progressive left lower extremity swelling for two months. Imaging revealed chronic left iliac vein occlusion and an incidental femoral arteriovenous fistula, presumed to be secondary to venous hypertension. The patient underwent endovascular recanalization via the contralateral femoral artery and ipsilateral popliteal vein access, with placement of two self-expanding stents from the common iliac to mid-femoral vein. Postoperative imaging confirmed stent patency and complete resolution of the arteriovenous shunt. The inferior vena cava (IVC) filter was successfully removed 20 days after the procedure.
conclusionIsolated iliac vein stenting can effectively resolve secondary FAVF by restoring venous outflow and reducing venous pressure. This minimally invasive strategy should be considered first-line therapy in patients with obstructive venous disease and concomitant FAVF.
