Percutaneous Versus Surgical Cannulation for Femoro-Femoral Venoarterial Extracorporeal Membrane Oxygenation: A Retrospective Cohort Study on Cannulation-Related Complications.
Article in Artificial organs, 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
backgroundCannulation for peripheral veno-arterial extracorporeal membrane oxygenation (V-A ECMO) can lead to severe local complications. This study evaluated site-specific complications between percutaneous and surgical cannulation techniques for femoro-femoral V-A ECMO, focusing on site bleeding, infection, and limb ischemia.
methodsWe conducted a single-center retrospective cohort study of adult patients who received femoro-femoral V-A ECMO either by percutaneous or surgical technique at a tertiary center. Cannulation-site complications were assessed from cannulation to post-decannulation. Risk factors for site bleeding, infection, and limb ischemia within 90 days of cannulation were analyzed using logistic regression.
resultsAmong 384 patients (22.4% female), 181 (47.1%) underwent percutaneous, and 203 (52.9%) underwent surgical cannulation. Percutaneous cannulation was associated with significantly fewer patients experiencing site bleeding (29.3% vs. 40.9%, p = 0.02) and infection (8.3% vs. 31.0%, p < 0.001), with no significant difference in limb ischemia (11.6% vs. 15.3%, p = 0.29). 90-day survival was similar between groups (43.6% vs. 49.8%, p = 0.81). Multivariable logistic regression identified surgical cannulation as an independent risk factor for site bleeding (OR 2.39, 95% CI 1.43-3.98; p < 0.001) and infection (OR 5.47; 95% CI 2.47-12.12; p < 0.001). Limb ischemia was not significantly associated with the cannulation technique but with two other modifiable factors at cannulation: absence of distal perfusion catheterization and larger arterial cannula size.
conclusionPercutaneous cannulation was associated with significantly fewer patients experiencing site bleeding and infection compared to surgical cannulation. Limb ischemia was not associated with the cannulation technique but was influenced by two other modifiable factors at cannulation: distal perfusion catheterization and arterial cannula size.
