Ultrasonographic images of patient 2 showing (a) two adjacent anechoic circles within the right lob of the liver. The smaller one was dilated right hepatic artery, and the big one was the aneurismatic dilation on the right main branch of portal vein which has turbulent flow within it (b) The dilated and tortuous right hepatic artery ending in the aneurism.

Also, we detected a fistula between the artery and the vein sonographically (Figure 1).
Angiographic images of patient 2 showing (a) dilated main hepatic artery and dilated right branch of the hepatic artery which ends in the aneurismatic dilation. The other branches of the celiac truncus and left branch of the hepatic artery were all normal in diameter (b) Aneurismatic dilation on the dilated right branch of the portal vein with retrograde filling. The other branches of portal system were all normal in diameter. (c) Control angiography of the patient, done 8 months after the detachable balloon treatment, showing complete occlusion of the arterioportal fistula.

Portal venous system has retrograde filling at the arterial phase of angiography (Figures 2(a) and 2(b)). On control angiography (Figure 2(c)), it was seen that the angiographic treatment was successful.

Her splenic artery was dilated from beginning just as originating from the celiac truncus and ends in the aneurism (Figure 3).
Angiographic images of patient 3 showing (a) dilated and tortuous splenic artery which ends in aneurism (b) similar to 4(a) with more filling of the aneurism and (c) dilated splenic vein together with splenic artery.
