Overview
Mesenteric artery vasculitis encompasses a group of rare disorders characterized by inflammation affecting mesenteric arteries, leading to potentially severe gastrointestinal complications such as ischemia and aneurysms. Diagnosis and management often require a multidisciplinary approach due to the complexity and variability of clinical presentations 2.Diagnosis
Clinical Symptoms: Abdominal pain, weight loss, and gastrointestinal bleeding are common 2.
Imaging: Vascular imaging (e.g., CT angiography, MRI) is crucial for noninvasive diagnosis, identifying vascular changes like aneurysms or occlusions 2.
Biopsy: While imaging is preferred, histopathological examination may be necessary for definitive diagnosis in some cases 2.
Differential Diagnosis: Exclude other causes of mesenteric ischemia and inflammatory bowel diseases 2.Management
First-Line Treatments:
- Corticosteroids: Oral corticosteroids are effective for controlling inflammation, as seen in successful treatment of nonspecific celiac artery vasculitis 1.
- Immunosuppressants: Additional immunosuppressants may be required for refractory cases 2.
Adjunctive Treatments:
- Endovascular Interventions: Increasingly used for symptomatic vasculitis, particularly for focal occlusive disease or aneurysms 2.
- Surgical Management: Mainstay for focal occlusive disease or aneurysms when endovascular options are insufficient 2.Special Populations
Pediatrics: Limited data; presentations may differ from adults 3 (Note: This abstract focuses on temporal arteritis, not mesenteric vasculitis).
Comorbidities: Management considerations for patients with HIV may require tailored immunosuppressive strategies 3.Key Recommendations
Utilize vascular imaging (CT angiography, MRI) for noninvasive diagnosis of mesenteric vasculitis to avoid unnecessary biopsies 2 (Evidence: Strong).
Initiate treatment with corticosteroids for controlling inflammation in mesenteric artery vasculitis 1 (Evidence: Moderate).
Consider endovascular interventions as a first-line treatment for symptomatic cases, especially when focal disease is present 2 (Evidence: Moderate).
Surgical intervention remains essential for managing focal occlusive disease or aneurysms when endovascular options are inadequate 2 (Evidence: Expert opinion).References
