Arterial lesions in Behçet's disease

Area of Science:

• Vascular Medicine
• Rheumatology
• Immunology

Background:

• Arterial involvement is a rare but serious complication of Behçet's disease.
• This study assesses therapeutic outcomes for arterial lesions in Behçet's disease patients.

Purpose of the Study:

• To evaluate the effectiveness of various treatments for arterial lesions in Behçet's disease.
• To determine the prognosis of pulmonary artery aneurysms and non-pulmonary arterial lesions in Behçet's disease.

Main Methods:

• Retrospective evaluation of 534 Behçet's disease patients diagnosed between 1987 and 2002.
• Follow-up intervals of 3 to 6 months to monitor arterial lesions.
• Analysis of therapeutic interventions including surgery, stent-graft insertion, and immunosuppressive therapy.

Main Results:

• Arterial lesions were found in 21 patients (3.9%).
• Pulmonary artery aneurysms (PAA) had a high mortality rate, with all three surgically treated patients dying. Survivors received cyclophosphamide and corticosteroids.
• Non-pulmonary arterial lesions were treated with surgery or stent-grafts; one patient died 8 years post-intervention. Corticosteroids were successful for occlusive lesions.

Conclusions:

• Pulmonary artery aneurysms in Behçet's disease carry a poor prognosis regardless of treatment.
• High-dose corticosteroids are effective for isolated non-pulmonary arterial occlusive lesions.
• Surgery or stent-graft insertion is recommended for non-pulmonary arterial aneurysms due to high complication risks.
