Figure 3. A 7-year-old girl with biliary atresia underwent left-lobe LDLT, PVS was suspected 5 years after LDLT, and portography was performed. (A) pretreatment portogram showing an anastomotic stricture (arrow), collateral vessels (arrowhead), and poor flow through the intrahepatic portal vein; (B) fluoroscopic view during balloon angioplasty showing the notch of the balloon at the stenosis; (C) portogram after the balloon angioplasty showing improved blood flow through the portal vein and disappearance of collateral vessels. PVS did not recur after the balloon angioplasty; LDLT: living donor liver transplantation; PVS: portal venous stenosis
