A large superior mesenteric artery aneurysm and ileal obstruction: a rare presentation of polyarteritis nodosa in an infant.

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
Polyarteritis nodosa (PAN) is a rare form of vasculitis that occurs in childhood and affects small- and medium-sized arteries. Large aneurysms due to PAN can induce fatal complications like rupturing or occlusion of the affected arteries. Here, we report a case of a 4-month-old girl with PAN complicated by a large superior mesenteric artery aneurysm and ileal obstruction. We controlled her blood pressure to prevent the artery from rupturing. A combination of prednisolone, intravenous cyclophosphamide, and plasma exchange reduced the inflammation. She developed mechanical ileus due to ileum stricture and underwent bowel resection. Histopathological examinations revealed reparative arteritis around the healed ulcer. Her postoperative course was uneventful without further dilatation of the aneurysm. This case highlights the importance of intensive immunosuppressive therapy and appropriate blood pressure control in pediatric patients with PAN complicated by large aneurysms. Mechanical ileus can develop and may require surgical management even after remission of vasculitis.
