Large-bore aspiration thrombectomy for the treatment of pulmonary embolism in octogenarians.
Article in CVIR endovascular, 2025. 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
purposeTo evaluate outcomes in patients aged ≥ 80 years following large-bore aspiration thrombectomy (LBAT) for the treatment of pulmonary embolism (PE). MATERIALS AND
methodsAll patients ≥ 80 years of age with PE treated via LBAT at a single center were analyzed from September 2019 - August 2024. This included the octogenarian subgroup from a recently published retrospective analysis assessing all PE patients treated with LBAT at our center between September 2019 and January 2023. The following outcomes were evaluated: technical success, change in several hemodynamic measures including pulmonary artery pressure (PAP) and right ventricle to left ventricle ratio (RV to LV ratio), length of hospital and intensive-care-unit (ICU) stay, procedure-related complications, and 7- and 30-day mortality.
resultsForty-eight patients aged ≥ 80 years underwent LBAT procedures for PE. Technical success was achieved in 46 cases (95.8%). The mean reduction in mean PAP was 3.6 mmHg. The mean reduction in RV to LV ratio was -0.42. The mean length of postprocedural hospital and ICU stays were 5.7 ± 3.6 days and 1.0 ± 1.6 days, respectively. There were 2 procedural complications, 1 pulmonary vascular injury involving a pulmonary artery pseudoaneurysm and 1 decompensation involving hypotension requiring vasopressor support. There were no major bleeding complications or cardiac injuries. All-cause mortality was 2.1% (n = 1) at 7 days and 6.3% (n = 3) at 30 days post procedure. PE-related mortality was 2.1% (n = 1) at 30 days.
conclusionLBAT is a technically feasible procedure for the treatment of PE in octogenarian patients and has a favorable preliminary safety and mortality profile.
