[Bowel ischaemia treated with stent placement]

Area of Science:

• Gastroenterology
• Vascular Medicine
• Rheumatology

Background:

• Polyarteritis nodosa (PAN) is a rare systemic vasculitis that can affect medium-sized arteries, including the mesenteric arteries.
• Mesenteric artery occlusion is a serious complication that can lead to bowel ischemia and significant morbidity.
• Early diagnosis and intervention are crucial for managing patients with PAN-associated mesenteric vasculitis.

Observation:

• A case report detailing a young woman presenting with abdominal pain and unintentional weight loss.
• Diagnosis of severe bowel ischemia was established via laparotomy four weeks post-admission.
• Clinical presentation and biopsy confirmed polyarteritis nodosa as the underlying cause.

Findings:

• Arteriography revealed occlusive disease in the mesenteric arteries.
• Successful endovascular treatment with stenting of the affected mesenteric arteries was performed.
• Despite perforation requiring resection of 10 cm of jejunum, the majority of the intestine was preserved.

Implications:

• This case highlights the importance of considering vasculitis, specifically polyarteritis nodosa, in the differential diagnosis of unexplained bowel ischemia in young adults.
• Successful revascularization via stenting can be an effective treatment modality, potentially avoiding extensive bowel resection.
• Prompt diagnosis and multidisciplinary management are key to improving outcomes in patients with polyarteritis nodosa affecting the mesenteric vasculature.
