Endovascular recanalization for symptomatic chronic carotid artery occlusion under local anesthesia: a single-center experience and meta-analysis.

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: Endovascular recanalization has gained increasing application in the treatment of patients with chronic carotid artery occlusion (CCAO). Despite its common use in the endovascular treatment of CCAO, it is unclear whether local anesthesia is associated with low peri-procedural complications. This study aimed to investigate the safety and efficacy of endovascular recanalization under local anesthesia for patients with symptomatic CCAO. Methods: Consecutive patients with symptomatic CCAO who underwent endovascular recanalization attempts under local anesthesia were retrospectively enrolled in this study. The recanalization attempts were discontinued if the patient reported intolerance. The recanalization success rate and peri-procedural complications were recorded. The underlying reasons for recanalization failure were investigated. A meta-analysis of the recanalization success and peri-procedural complication rates of the CCAO patients who underwent recanalization under local anesthesia was also conducted. Results: In total, 69 patients were enrolled in the study. The recanalization success and peri-procedural complication rates were 68.1% and 2.9%, respectively. No iatrogenic vascular complications occurred. Recanalization failed in 22 patients, of whom, the cavernous segment could not be navigated in 14 patients, and the extracranial segment could not be transversed in eight patients. A total of seven studies, including this study, were included in the meta-analysis. Overall, the recanalization success rate was 66.2% [95% confidence interval (CI): 61.2% to 70.1%, I Conclusions: Endovascular recanalization for CCAO under local anesthesia was feasible and was associated with a low rate of peri-procedural complications.
