Fig. 1B —18-year-old man with portal vein thrombosis and variceal
bleeding (patient 3, Table 2).
Patient had previously undergone splenectomy for lymphoma. Angiographic images
in anteroposterior projection demonstrate transjugular intrahepatic
portosystemic shunt procedure. Left portal vein was punctured under
sonographic and fluoroscopic guidance, and injection of contrast material
showed presence of portal cavernoma with opacification of right portal branch
(A, arrow). Track was created between right hepatic vein and
right portal branch (B), and Viatorr stent-graft (diameter, 10 mm;
length, 80 mm; W. L. Gore and Associates) was successfully deployed
(C), with reduction of portosystemic pressure gradient from 19 to 7 mm
Hg.
