A superior mesenteric arteriography, obtained in the venous phase, confirmed an end-to-side porto-caval shunt with no intrahepatic portal vein, superior mesenteric vein joined the splenic vein and then the confertus splanchnic vein bypassed the liver and drained into the IVC (Figure 1).
Selective lung angiography showing diffuse small reticular end-on vessel pattern on both lungs and immediate imaging of the left atrium, suggestive of pulmonary arteriovenous fistula (PAVF).

Right cardiac catheterization showed a normal pulmonary artery pressure of 15 mmHg and selective lung angiography showed diffuse small reticular end-on vessel pattern on both lungs and immediate imaging of the left atrium, suggestive of pulmonary arteriovenous fistula (PAVF) (Figure 2).
