Flow Diversion for an Extracranial Infectious Internal Carotid Pseudoaneurysm Secondary to Exudative Otitis Media: Illustrative Case.
Article in Journal of neuroendovascular therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Treatment of infectious aneurysms is challenging because of the fragility of the vessel walls. Surgical trapping and endovascular parent artery occlusion are the treatments of choice for medically intractable infectious aneurysms. Here, we describe a patient with an infectious aneurysm at the extracranial petrous segment of the internal carotid artery that was secondary to exudative otitis media; it was successfully treated with reconstructive endovascular interventions using a flow redirection endoluminal device (FRED). Case Presentation: A 57-year-old man was administered antibiotics for exudative otitis media. After 6 months, the patient underwent CT screening, which revealed destruction of the petrous bone and a pseudoaneurysm at the petrous segment of the left internal carotid artery. Catheter angiography, including a balloon occlusion test, revealed a 47-mm wide-necked pseudoaneurysm at the distal cervical segment of the left internal carotid artery with poor collateral blood supply to the left internal carotid artery. We performed reconstructive endovascular treatment using a FRED. A follow-up catheter angiogram after 6 months confirmed a minor neck remnant of the aneurysm. Conclusion: Flow diversion may be a useful treatment approach for extracranial infectious aneurysms, despite concerns about incomplete obliteration of the aneurysm and the persistent risk of re-rupture before complete obliteration.
