Endovascular intravascular intervention for central venous stenosis in maintenance hemodialysis patients: a retrospective observational study.
Article in Frontiers in cardiovascular medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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: The number of people undergoing maintenance hemodialysis is increasing rapidly worldwide. Central vein stenosis (CVS) is a common vascular complication in undergoing hemodialysis, especially those with a history of catheterization. This study aimed to investigate the characteristics of CVS and the clinical effectiveness of percutaneous transluminal angioplasty (PTA) alone and sequential percutaneous transluminal stenting (PTS) in hemodialysis patients with CVS. Methods: A retrospective analysis of 26 cases of endovascular intervention for CVS using PTA alone or sequential PTS was performed. The characteristics of CVS and the clinical effectiveness of these procedures were evaluated. Results: This study included 26 hemodialysis patients who presented with symptomatic CVS. Of these 26 patients, 53.85% were male, and their mean age was approximately 54.96 years. All the patients had a history of catheter placement or pacemaker implantation. The incidence of brachiocephalic vein stenosis was significantly higher than that of subclavian vein stenosis (46.16% vs. 26.92%). Based on the degree of stenosis and elastic retraction, these patients were administered PTA alone or sequential PTS. There was no difference in patient age, hemodialysis time, catheter retention time, or stenosis length between the PTA alone and sequential PTS groups. However, the degree of venous stenosis in the PTS group was more severe than that in the PTA alone group. The primary patency rates in the sequential PTS and PTA alone groups were 94.12% and 100% at 3 months; 88.24% and 88.89% at 6 months; 75.00% and 85.71% at 9 months; and 66.67% and 71.43% at 12 months, respectively. It is worth noting that for 7 patients with complete occlusion of the brachiocephalic vein, we used sharp recanalization technology and stenting placement, with patency rates of 85.71% and 71.43% at 6 and 12 months, respectively. Conclusions: PTA alone is recommended for patients with less than 50% central venous elastic retraction, while sequential PTS is recommended for patients with ≥ 50% central venous elastic retraction. PTA and PTS are safe and effective methods for the treatment of CVS in patients undergoing hemodialysis.
