Trans-Cell Technique through Mesh of Pipeline Embolization Device: A Case Report.
Article in Journal of neuroendovascular therapy, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Objective: We report a case of coil embolization using trans-cell technique through mesh of a pipeline embolization device (PED). Case Presentation: A 55-year-old female developed a left cavernous carotid aneurysm (CCA) with left abducens nerve palsy. The abducens nerve palsy improved gradually after PED deployment for the aneurysm. Sixty-nine days after the procedure, the patient suddenly presented with a severe headache, left abducens nerve palsy, left eyelid edema, and left pulsatile tinnitus. Digital subtraction angiography (DSA) revealed left direct carotid cavernous fistula (dCCF) due to rupture of the aneurysm, and the patient underwent endovascular treatment. A Marathon was guided into the left internal carotid artery, and a guidewire via the Marathon passed through the mesh of the PED. Then the Marathon advanced over the guidewire into the aneurysm through the mesh of the PED, with assistance of a distal access catheter and a balloon catheter. Transarterial intra-aneurysmal coil embolization using trans-cell technique was performed, and the shunt blood flow was diminished. After subsequent transvenous embolization (TVE), the shunt blood flow disappeared, and all neurological symptoms improved. When PED is deployed linearly at a diameter 0.5 mm smaller than the nominal diameter, the average strand spacing is calculated to be approximately 0.2 mm. Since PED is a braided stent, the spacing can be large. It is theoretically reasonable for Marathon with an outer diameter of 0.59 mm to pass through the mesh of the PED. Conclusion: In some cases, trans-cell technique through mesh of PED can be performed using a small diameter microcatheter.
