1 · What the graph read from it

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.

2 · The registry

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

backgroundThe objective of this study is to examine factors associated with thrombus extension after early experience with mechanochemical ablation, which combines mechanical damage to the venous endothelium with infusion of a sclerosant.

methodsA retrospective review was performed of patients who underwent mechanochemical ablation to treat saphenous vein insufficiency in the thigh including the saphenofemoral junction. Data abstracted included patient demographics, procedural details, and postprocedural outcomes. Thrombus extension was determined by postprocedural duplex ultrasound and classified as flush closure with the femoral vein and any extension of thrombus into the femoral vein.

resultsSeventy-three patients met inclusion criteria. The mean age of the population was 60, 17.8% were female, and the mean body mass index (BMI) was 30.7. Seven (9.6%) patients who underwent mechanochemical ablation experienced saphenous vein closure flush with the femoral vein. Eleven (15%) patients experience extension of thrombus to less than 50% of the diameter of the femoral vein and one patient experienced complete thrombosis of the femoral vein. There was no significant difference in age, sex, or comprehensive classification system for chronic venous disorders between the group with thrombus extension and the group without, with the exception of BMI. The mean BMI in the group with thrombus extension was 26.8 vs. 32 in the group without (P = 0.02). There was no significant difference between the 2 groups in sclerosant volume used, distance between catheter tip and SFJ, and mean diameter of GSV in the thigh.

conclusionsIn this cohort, the incidence of thrombus extension into the femoral vein with mechanochemical ablation was high relative to rates of thrombus extension associated with reported rates of thermal ablation. Further investigation with larger cohorts, and standardized reporting is required to characterize the true rate of thrombus extension after mechanochemical ablation and identify maneuvers which may prevent thrombus extension.
