Percutaneous transluminal angioplasty for persistent primitive hypoglossal artery stenosis: illustrative case.

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
backgroundWe report a case of symptomatic, progressive stenosis of a persistent primitive hypoglossal artery (PPHA), which was successfully treated with percutaneous transluminal angioplasty (PTA) of the origin of the PPHA. The PPHA is a type of carotid-basilar anastomosis with an incidence of 0.02% to 0.10%. It originates from the internal carotid artery (ICA), passes through the hypoglossal canal, and merges with the basilar artery. In many cases, the ipsilateral vertebral artery is hypoplastic; therefore, PPHA stenosis causes cerebral infarction in the posterior circulation territory, as in this case. OBSERVATIONS: The patient's right PPHA had severe and progressive stenosis; therefore, he experienced cerebral infarction despite medical treatment. Therefore, PTA for the stenosis was performed, which ceased the recurrence of cerebral infarction and dizziness by improving blood flow in the posterior circulation. LESSONS: Several reports have described ICA stenosis accompanied by PPHA or PPHA stenosis in patients receiving endovascular treatments. Almost all cases were nonprogressive, and the treatment procedure was stenting. However, in our case, the PPHA stenosis was progressive, and we performed PTA because the patient experienced resistance to antiplatelet drugs and had poor collateral flow.
