Pulmonary thromboembolism exacerbated by thrombus migration through an inferior vena cava filter: a case report.

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: Pulmonary thromboembolism (PTE) is a life-threatening condition requiring prompt and effective treatment. Current treatment options include anticoagulation therapy, catheter-directed therapies, and surgical interventions. While inferior vena cava (IVC) filters are widely used for PTE prophylaxis in high-bleeding-risk patients, their failure mechanisms and optimal alternatives remain understudied, particularly in intermediate-high-risk PTE cases where anticoagulation fails. Case summary: We present a case of intermediate-to-high-risk PTE in a 61-year-old woman who experienced recurrent embolization despite receiving anticoagulation therapy. Although an IVC filter was deployed to prevent further embolization, a thrombus from the superficial femoral vein migrated through the tilted IVC filter, and surgical thrombectomy was performed. Discussion: This case emphasizes the need for careful IVC filter placement to prevent tilt-related complications and supports the adoption of advanced catheter-based thrombectomy devices to enhance the efficacy of PTE treatment and reduce the need for surgical intervention.
