A safe seal: controlled flow arrest with dual balloon protection for embolisation of a large spontaneous splenic arteriovenous fistula-a case report.
Article in CVIR endovascular, 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
backgroundSplenic artery aneurysm (SAA) with splenic arteriovenous fistula (SAVF) is rare. Endovascular embolisation offers a minimally invasive, spleen-preserving alternative to surgery, particularly in patients with connective tissue disorders. This case report describes a technically challenging proximal SAA with high-flow SAVF successfully treated using dual-balloon-assisted coil and N-butyl cyanoacrylate (NBCA) glue embolisation, with special consideration for vascular Ehlers-Danlos syndrome (vEDS). CASE PRESENTATION: A 28-year-old short-statured woman with micrognathia had computed tomography (CT) showing a partially thrombosed proximal SAA and early arterial-phase enhancement of portomesenteric veins. Given her young age and constitutional features, an underlying connective-tissue vasculopathy such as vEDS was suspected. Dual-balloon flow control was achieved using a 6 × 15 mm Eclipse balloon at the hepatic-coeliac bifurcation (arterial inflow control) and a 12 × 40 mm Mustang balloon in the splenic vein (venous outflow control), followed by dense coil packing and controlled NBCA injection. Post-embolisation angiography and follow-up CT demonstrated exclusion of the aneurysm-fistula complex with preserved hepatic and portal venous flows and viable splenic parenchyma.
conclusionDual-balloon-assisted coil and N-butyl cyanoacrylate (NBCA) embolisation enables precise, controlled flow arrest in high-flow SAA-SAVF, minimising non-target embolisation. This case highlights its value as a safe, spleen-preserving, and durable option-particularly relevant in patients with suspected connective-tissue disorders such as vEDS, where arterial fragility mandates meticulous endovascular technique. LEVEL OF EVIDENCE: 4 (Case Report).
