Observation of patency rates in patients with arteriovenous fistula stenosis treated with paclitaxel-coated high-pressure balloon angioplasty.
Trial report in Langenbeck's archives of 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
objectiveThis study aimed to observe the patency outcomes in patients with arteriovenous fistula (AVF) stenosis treated with paclitaxel-coated high-pressure balloon angioplasty.
methodsEighty patients with AVF stenosis were randomly assigned to two groups (n = 40 each). The control group underwent conventional balloon angioplasty, while the observation group received paclitaxel-coated high-pressure balloon angioplasty. Baseline characteristics were recorded. Changes in vascular diameter, dialysis blood flow, and peak systolic velocity at the stenotic site were compared pre- and post-treatment. Surgical success rate and restenosis rates were recorded. Fistula patency was followed at multiple postoperative time points, and postoperative quality of life was assessed using the WHOQOL-BREF scale.
resultsBaseline characteristics were comparable between the two groups (P > 0.05). Following the treatment, the observation group demonstrated greater improvements in vascular diameter, dialysis blood flow, and peak systolic velocity than the control group (P < 0.05). Although technical success did not differ markedly, the observation group experienced a lower rate of restenosis (P < 0.05). Fistula patency rates at 3-9 months postoperatively showed no significant difference (P > 0.05), but at 12 months, the observation group exhibited higher patency rates (P < 0.05). Postoperative quality-of-life scores were higher in the observation group (P < 0.05).
conclusionPaclitaxel-coated high-pressure balloon angioplasty may offer notable benefits for AVF stenosis, including enhanced long-term patency, and reduced restenosis, ultimately contributing to better patient-reported quality of life.
