Behcet's disease and iatrogenic arterial complications: value of pre-operative noninvasive explorations.

We report a case of Behcet's disease complicated with a popliteal aneurysm, which appeared 8 years after first, etiologic diagnosis. The points of int erest of this observation are the pre-operative explorations and particular ly the Magnetic Resonance Angiography (RMA). This last seems to be particul arly safe for aortic and lower limbs aneurysms explorations, and can be per formed without arterial ponctions. In fact the risk of arteriogram is effe ctive in Behcet's disease with secondary false aneuryms. RMA and US-Doppler scan must be first proposed in Behcet's disease in case of aortic and peri pheral aneurysms.
