Non-specific arteritis ofhe aorta and its main branches.

Area of Science:

• Cardiovascular Pathology
• Systemic Vasculitis
• Aortic Diseases

Background:

• Non-specific arteritis can affect the aorta and its major branches.
• This condition may present with diverse clinical and pathological findings.

Purpose of the Study:

• To describe four cases of non-specific arteritis involving the aorta.
• To discuss the nomenclature, diagnostic criteria, and pathogenesis of this condition.

Main Methods:

• Case series review of four patients with non-specific arteritis.
• Clinical data, imaging, and necropsy findings were analyzed.
• Literature review for comparative analysis.

Main Results:

• Four cases presented with aortic and branch artery involvement.
• Three cases were hypertensive; one had aortic incompetence.
• Systemic disturbances included polyarthritis, fever, weight loss, elevated ESR, and hyperglobulinemia.
• Case 4 showed abdominal aortic coarctation; Case 2 had dissecting aneurysms.

Conclusions:

• Non-specific arteritis of the aorta is a rare condition with varied presentations.
• Systemic manifestations are common.
• Further research is needed to clarify pathogenesis and establish diagnostic criteria.
