[Post-traumatic arteriovenous fistula: apropos of 4 cases]

Postraumatic arteriovenous fistulas (AVF) usually occur after traumatisms or surgical procedures. A clinic hemodynamic repercussion, or even a cardiac failure, can be caused by them. AVF diagnosis is mainly made angiographic study. In the present works we study different "Diagnosis by Images" methods (i.e.: CT, echography, MNR, angiography, gammagraphy, etc.) used in AVF diagnosis. Also, a Bibliographic Review of such disease was made. We present four cases reports with postraumatic arteriovenous fistulas; two were located in extremities (right upper limb and left lower limb, respectively) and the other two were abdominal (left reno-renal and right renocava).
