Resume Propos Compte tenu des resultats obtenus dans une serie de patients et d'une revue de la litterature, les auteurs precisent la place du traitement medical et les possibilites therapeutiques chirurgicales en fonction des differentes localisations des anevrismes lies a la maladie de Behcet. Methodes Il s'agissait d'une etude prospective de cinq anevrismes lies a la maladie de Behcet chez trois patients. Resultats Devant un anevrisme arteriel, le diagnostic de maladie de Behcet reste difficile dans les formes incompletes. Les anevrismes peuvent toucher tous les territoires arteriels, mais la localisation aortique reste la plus frequente (deux patients). Les trois patients ont ete operes et ont beneficie d'une revascularisation utilisant de preference du materiel prothetique. Deux des trois patients ont ete mis sous acide acetyl salicylique, colchicine et cyclophosphamide en bolus. Le suivi moyen a ete de 22 mois. Un patient a presente une recidive. Un autre anevrisme est apparu en un autre territoire chez un autre patient. Conclusion Ces lesions arterielles repondent peu au traitement medical qui associera de preference la colchicine et le cyclophosphamide en bolus mensuel. Les indications chirurgicales doivent rester larges mais selectionnees, utilisant des protheses plutot que du materiel veineux(risque d'atteinte veineuse spontanee). La place du traitement endoluminal reste a preciser. La possibilite de complications et de recidive imposent un suivi prolonge.

Results that were obtained from three patients and a literature review allow the authors to better define the place of medical and surgical treatments according to the different locations of arterial aneurysm occurring in the course of Behcet's disease.Retrospective report of five cases of arterial aneurysm that occurred during Behcet's disease in three patients.Due to the unusual symptoms, diagnosis can be hampered. Though lesions may be observed in various areas, they were mostly aortic (two patients). Surgical revascularization was done in all three patients. It mainly involved prosthetic grafts. Two patients were subsequently treated by postoperative immunosuppressive drugs. The mean follow-up was 22 months. Relapsing aneurysm was observed in one patient, while in another patient aneurysm developed in a new location.These types of arterial lesions respond poorly to medical treatment when a combination of colchicine and intermittent intravenous bolus of cyclophosphamide is used. Surgical indications should be given great yet selected weight, using prosthetic rather than venous autologous grafts (due to the risk of spontaneous venous involvement). Since either complication or recurrence is possible, prolonged monitoring is required.
