Surgical thrombectomy for iliofemoral deep vein thrombosis: Patient outcomes at 8.5 years.
Article in PloS one, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
introductionDeep vein thrombosis (DVT) is a frequent burden and a post-thrombotic syndrome (PTS) can be a serious long-term consequence. Iliofemoral DVT should be associated with severe forms of PTS. Therefore an early thrombus removal has been recommended in specific conditions. The aim of this study was to find out both, the long-term results after surgical thrombectomy of iliofemoral DVT in respect of the development of PTS as well as the venous hemodynamics after surgery concerning venous reflux and venous obstruction.
methodsSixty-seven patients who underwent surgical thrombectomy between the years 2000 and 2014 were included in this study; iliofemoral DVT was present in 52 of these patients. 35 patients could be reinvestigated after a mean follow-up of 8.5 years. CEAP (Clinical-Etiological-Anatomical-Pathophysiological) and Villalta scores were recorded in order to describe and assess PTS. Follow-up examinations included a detailed duplex mapping. Venous hemodynamics were measured by digital photoplethysmography and venous occlusion plethysmography.
resultsThe primary patency rate of the iliofemoral segment was 88% after 8.5 years. 48% of all patients showed reflux in deep vein segments. Mild or moderate PTS occurred in 57% of all patients. Notably, there was no patient with an active ulcer or severe PTS. The mean venous outflow volume of all patients in the treated legs was 66.1 ml/100ml/min and significantly less than in the controlled contralateral non-treated legs (p<0.05). The mean venous refilling time was 16.3 seconds, while the mean value of the non-treated contralateral legs was 25.6 seconds and therefore significantly higher (p<0.05).
conclusionEven though venous hemodynamics are significantly inferior in the treated legs, this study demonstrates excellent patency rates and good clinical outcome after surgical thrombectomy of iliofemoral veins.
