Percutaneous portal venoplasty and stenting for anastomotic stenosis after liver transplantation

Figure 2 A 28-year-old man with a pre-existing meso-caval shunt. A: Initial portography revealed an almost occlusive anastomosis; B: Portography detected a pre-existing meso-caval shunt due to visualization of the inferior vena cava; C: After stenting, the contrast agents flowed mainly into the inferior vena cava via the shunt and little flowed into the portal vein; D: A covered stent was deployed into the superior mesenteric vein to occlude the shunt. Portal hepatopetal flow was restored and the inferior vena cava became invisible.
