Primary angioplasty for a subtype of symptomatic middle cerebral artery stenosis.
Article in Neuroradiology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
introductionThe purpose of this study was to assess the long-term efficacy of middle cerebral artery revascularisation by primary balloon angioplasty for the prevention of stroke in a certain subtype of patients.
methodA retrospective study was performed to evaluate 33 patients with symptomatic middle cerebral artery stenoses who underwent primary balloon angioplasty; the selection criteria were: greater than 70% stenosis measured by digital subtraction angiography, lesions equal to or shorter than 5 mm, lesions near or across a bifurcation, and lesions with very tortuous proximal vessels that increase the risk of stenting. All patients were available for follow-up ranging from 6 to 60 months. The technical success rate, periprocedural complications, and long-term outcome were retrospectively reviewed.
resultThe mean stenosis degree was reduced from 87.12 ± 7.40 to 23.03 ± 9.84 after angioplasty. The periprocedural complication rate was 18.18% (six dissections without an ischemic event). Two patients had strokes in the territory of the angioplasty at 6 and 32 months after angioplasty, and the stroke-free survival at 5 years was 90.04% (mean survival time, 56.42 ± 2.43 months; 95% CI, 51.66-61.19 months).
conclusionThese results suggest that this treatment is safe and could provide a durable clinical result at long-term follow-up in this subtype of patients, but the high rate of dissection remains a major technical drawback.
