Embolization of a vertebral artery encased in a regrowth cervical meningioma before resection.

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: Managing intraoperative bleeding may be challenging when a cervical tumor encases the vertebral artery (VA). Here, a patient with a recurrent cervical meningioma between the C1/2 and C3/4 levels and encasement of the right VA injury developed intraoperative bleeding that was endovascularly embolized postoperatively. Case Description: A 30-year-old female presented with a progressive quadriparesis, most markedly involving the right upper extremity. Six years ago, she had a cervical meningioma resected at the C2/3 level. The new MR revealed regrowth of intraspinal tumor between the C1/2 to C4/5 levels accompanied by extradural encasement of the right VA within the C2/3 and C3/4 foramina. Before the first surgery, the right VA was embolized (i.e., after a balloon occlusion test proved negative). During the attempted resection of the intradural/extradural tumor, bleeding from the right VA was encountered; it was temporarily controlled. After complete occlusion of the right VA was angiographically confirmed, a second-stage procedure to fully resect the extradural remanent of the tumor was undertaken. Conclusion: Endovascular embolization of the right VA before the attempted resection of a recurrent intraspinal/extraspinal cervical meningioma failed to occlude the vessel entirely. The VA bleeding encountered intraoperatively was temporarily controlled. Delayed total VA occlusion was angiographically observed before full tumor resection could be completed.
