Chronic Femoropopliteal Occlusions: Comparison of Drug-Eluting Balloon Angioplasty with or without Prior Rotational Thrombectomy.

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
backgroundThe aim of this study was to compare drug eluting balloon (DEB) angioplasty with and without mechanical thrombectomy system in patients with chronic (> 6 months) femoropopliteal occlusions.
methodsWe retrospectively identified patients from May 2012 to September 2014 at our clinic with severely diseased femoropopliteal arteries treated by endovascular approach with or without adjunctive thrombectomy system. All patients had ankle-brachial index (ABI) measured before and after the intervention, and regular clinical follow-up with Doppler ultrasonography performed at 1 month, 6 months and 1 year. Patients underwent peripheral angiography if needed.
resultsMechanical thrombectomy system (MTS + DEB) was used in 33 patients (31 enrolled 2 patients were lost to follow-up, mean lesion length 149.7mm ± 82.69). The remaining 33 patients were treated without MTS (31 enrolled 2 patients were lost to follow-up DEB N = 31 mean lesion length 157.3 mm ± 92.90). There were 5 restenosis in the MTS + DEB group (83.3% patency rate) and 5 restenosis in the DEB group (82.8% patency rate) at 1 year. The technical success rate was 93.5% in both groups. A statistically significant increase in the ABI (MTS + DEB before 0.47 ± 0.11 vs. after 0.92 ± 0.11 p < 0.01 DEB before 0.47 ± 0.11 vs. after 0.90 ± 0.14 p < 0.01) and improvement in Rutherford staging (p < 0.01) was noted in both groups following intervention.
conclusionsDEB angioplasty is effective in the treatment of chronic total femoropopliteal occlusions. Combining DEB angioplasty and thrombectomy system does not appear to improve outcomes for treatment of chronic femoropopliteal occlusions.
