Introduction:
Polyarteritis 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.
Conclusion:
This 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.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
