Complex presentation of polyarteritis nodosa: Renal pseudoaneurysm rupture and bowel ischemia: A case report.

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
introductionPolyarteritis Nodosa (PAN) is a rare vasculitis of medium-sized arteries with severe complications, including Renal artery aneurysm (RAA)rupture and gastrointestinal ischemia. Early recognition and intervention are crucial for improving outcomes. PRESENTATION OF CASE: A 21-year-old male with a history of PAN presented with acute flank pain, rash, confusion, and anemia. Imaging revealed a ruptured RAA with retroperitoneal hemorrhage. He developed bowel ischemia confirmed by colonoscopy and computed tomography scan. The patient underwent renal artery embolization and exploratory laparotomy, revealing gangrenous cecum and ileal perforation, requiring hemicolectomy and ileal resection. Postoperatively, he was treated with immunoglobulin, cyclophosphamide, and prednisone, resulting in significant improvement. DISCUSSION: PAN can cause life-threatening complications, including vascular rupture and ischemia. Embolization effectively controlled bleeding, and surgery addressed ischemic damage. Early intervention with immunosuppressive therapy played a key role in recovery.
conclusionThis case emphasizes the need for prompt recognition and treatment of severe PAN complications. Early surgical intervention and appropriate immunosuppressive therapy are essential for preventing fatal outcomes.
