Percutaneous transarterial embolization of extrahepatic arteroportal fistula

Figure 1 Color –Doppler US showed an anechoic mass, 2. 5 cm in diameter, next to the head of the pancreas with turbulent flow inside.

Figure 2 MDCT 3D reconstruction showed the presence of a large aneurysm filled with a dilated gastroduodenal artery and draining into the superior mesenteric vein.

Figure 3 Celiac axis arteriogram confirmed a large aneurysm of gastro-duodenal artery and a fistulous communication with the main portal vein.

Figure 4 Arteriogram performed after coils embolization showed complete occlusion of the fistula.
