Extra-Corporeal thermal ablation with High Intensity Focused Ultrasound for superficial venous insufficiency: Preliminary results at twelve months follow-up.

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
ObjectiveThe aim of this study is to present our results with an innovative extracorporeal thermal therapy using High Intensity Focused Ultrasound (HIFU) to treat Superficial Venous Insufficiency (SVI).DesignObservational retrospective study with prospective data collection.MethodsA total of 102 consecutive patients were included. All types of incompetent veins that met the HIFU-device criteria were treated. The primary endpoint of our analysis was vein occlusion rate. As secondary endpoints, shrinkage, absence of reflux, clinical improvement and complications related to the treatment were analyzed. Clinical and Ultrasound (US) follow-up was planned at 15 days, 3 months, 6 months, and 12 months. For clinical assessment, simplify CEAP classification and Venous Clinical Severity Score (VCSS) were registered.ResultsA total of 164 veins were treated: 92 saphenous trunks [65 Great Saphenous Veins (GSV), 15 Short Saphenous Veins (SSV), 12 Anterior Accessory Saphenous Veins (AASV)], 48 perforator veins and 24 other veins (15 tributaries, 4 Giacomini veins, 5 neovascularizations). For all types of veins, occlusion rates were 85% to 96% at early follow-up and from 85% to 90% twelve months after the treatment. Regarding reflux-free rate, it ranged from 85% to 96% 2 weeks after treatment, and from 85% to 93% at twelve months. Finally, shrinkage rates ranged from 96% to 97% 2 weeks after the treatment, and from 94% to 97% at twelve months. All patients showed statistically significant clinical improvement in VCSS and CEAP classification trough the different follow-ups. No major adverse events were observed.ConclusionTreatment of varicose veins with the HIFU therapy seems to be competitive with the state-of-the-art techniques and has shown to be effective and safe in our initial 102 patients' data analysis. Nevertheless, further studies are needed for stronger evidence.
