Mechanical Thrombectomy for the Treatment of Iliofemoral Deep Venous Thrombosis using the ClotTriever System: A Single-Centre Experience.
Article in Cardiovascular and interventional radiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeIliofemoral deep venous thrombosis (DVT) is a significant cause of morbidity, with up to 50% of patients developing post-thrombotic syndrome (PTS). Mechanical thrombectomy (MT) has been proposed to restore early vessel patency and reduce PTS risk. This study evaluated outcomes of patients with iliofemoral DVT treated using Inari's ClotTriever system. MATERIALS AND
methodsA retrospective review was conducted of consecutive patients with iliofemoral DVT treated with ClotTriever. Technical success (defined as ≥ 75% thrombus removal and restoration of vein patency) and patency rates were assessed up to 12 months. Primary patency was defined as maintained patency without reintervention; assisted primary patency included reintervention without re-occlusion, and secondary patency referred to restored patency after occlusion. PTS was assessed using the Villalta score at a median follow-up of 4 months. Hospitalisation length, complications, and 30-day mortality were also recorded.
resultsNinety limbs in 81 patients were treated. Thrombus chronicity was acute (30.0%), subacute (35.6%), and chronic (34.4%). Technical success was achieved in 98.9% of limbs. Primary patency rates at 6 and 12 months were 78.8% and 76.2%, respectively; assisted primary patency rates were 84.3% and 81.7%, and secondary patency remained 95.5%. Median Villalta score improved from 10.5 to 1.0 (p < 0.0001). At follow-up, 89.8% of limbs were PTS-free; 10.2% had mild PTS, with no moderate/severe cases. Median hospital stay was 1 day. No major complications or 30-day mortality occurred.
conclusionClotTriever MT achieved high technical success, sustained patency, and significant symptom improvement. Comparative trials are needed to confirm its efficacy versus standard anticoagulation.
