[Arteriovenous malformations].
Arteriovenous malformations are serious high-flow vascular malformations. Four progressive stages have been described: dormancy, expansion, destruction and heart failure. Progression from one stage to another is not systematic but depends on events - physiological or traumatic, sometimes iatrogenic. Pulsed Doppler imaging of venous waveforms and magnetic resonance imaging (MRI) are the most informative examinations for both diagnosis and follow-up of arteriovenous malformations.Arteriography and angio-MRI help guide treatment decisions. Treatment of the malformation must not be envisioned until it reaches a symptomatic stage. It most often combines an endovascular procedures and wide surgical excision. A syndromic form must be considered in cases of systemic angioma.
