title: Sonographic diagnosis of arterioportal fistula.
abstract: OBJECTIVE
  We aimed to identify and describe characteristic and diagnostic ultrasonographic features of arterioportal fistula cases.
  
  
  METHODS
  In this case series we describe 3 patients with arterioportal fistula. By depending on shared sonographic features of these patients we describe a "sonographic pattern" for the sonographic diagnosis of arterioportal fistula.
  
  
  CONCLUSIONS
  In summary; both of the artery and vein related with fistula were wider than normal and seen as adjacent anechoic circles, there was an aneurysmatic dilation on vein which has turbulent flow within it, the communication between the artery and aneurysm can be seen sonographically, both of the vessels have arterial flow, filling of the vein was retrograde and other branches of the artery and vein unrelated with aneurysm were all normal in dimension.
