Angiographic Patterns and Outcomes Achieved by Proximal Balloon Occlusion in Symptomatic Carotid Artery Stenosis Stenting.
Article in Clinical neuroradiology, 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
background and purposeThe best embolic protection strategy has not yet been established for carotid artery stenting (CAS). This article reports a new simplified approach using a balloon guide catheter inspired by stroke therapy, in patients harboring a symptomatic ICA atherosclerotic stenosis or web. In addition, the three angiographic patterns and clinical outcomes associated with this technique, called the simple flow blockage (SFB) technique are described. MATERIAL AND
methodsThis was a retrospective study with data extraction from a monocentric prospective clinical registry of consecutive patients admitted for symptomatic ICA stenosis or web. The primary study outcome (composite endpoint) was the rate of occurrence of death, symptomatic stroke or acute coronary syndrome within 30 days of the intervention.
resultsIn this study 75 symptomatic patients with >50% carotid artery atherosclerotic stenosis or web were included. All procedures were successfully performed. The composite endpoint occurred in 3 patients (4.0%, 95% confidence interval, CI, 0.0-11.3): 1 had symptomatic ischemic stroke, 1 had reperfusion syndrome with symptomatic intracranial hemorrhage and 1 had acute coronary syndrome. After proximal balloon inflation three angiographic patterns were observed: complete contrast column stagnation in the ICA (38.7%), retrograde washout of the ICA from the intracranial circulation towards the external carotid artery (35.5%) and antegrade washout of contrast medium towards the intracranial circulation (25.8%). The median procedure length was 40 min. New asymptomatic ischemic lesions were observed in 22.5% on DWI-MRI.
conclusionThe SFB technique enables fast and safe procedures in CAS. A favorable angiographic pattern after proximal balloon inflation was observed in 74.2% of cases.
