1 · What the graph read from it

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.

2 · The registry

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

purposeTo highlight the clinical and diagnostic importance of correctly identifying cervical internal carotid artery fenestration (fcICA), an extremely rare vascular anomaly, and to present a case where fcICA was initially misdiagnosed as a dissection in a patient with fibromuscular dysplasia (FMD).

methodsA 47-year-old woman with pulsatile tinnitus underwent computed tomography angiography (CTA) and digital subtraction angiography (DSA) to differentiate between fenestration and dissection of the internal carotid artery.

resultsCTA revealed a fusiform dilatation of the distal C1 segment of the right internal carotid artery (ICA) with a linear filling defect, suggesting either fenestration or dissection. DSA confirmed the presence of a fenestrated right ICA segment composed of two symmetrical, smooth-walled limbs without a dissection flap, along with signs of FMD in the proximal vessel. The patient's symptoms were attributed to local flow perturbations induced by fcICA and FMD.

conclusionThis case illustrates that fcICA can be a true anatomical variant rather than a result of dissection, emphasizing the need for accurate imaging and diagnosis to avoid unnecessary treatments. The coexistence of fcICA with FMD increases the risk of dissection, necessitating careful monitoring. The distinction between fenestration and pseudofenestration remains challenging, requiring comprehensive imaging and close collaboration between radiologists and vascular neurologists.
