Computed tomography-based score model/nomogram for predicting technical and midterm outcomes in transjugular intrahepatic portosystemic shunt treatment for symptomatic portal cavernoma

Figure 2 A 54-year-old man with refractory ascites who underwent transjugular intrahepatic portosystemic shunt. A: Contrast-enhanced coronal portal venous phase computed tomography image shows complete nonvisualization of the main portal vein (cavernous transformation of the portal vein score is 4); B: Percutaneous trans-hepatic portography demonstrated the same appearance as computed tomography; C: Balloon-assisted shunt creation; D: The patient developed massive ascites 9 mo later after shunt creation. Doppler ultrasonography revealed absent flow in the shunt; E: After balloon-assisted transjugular intrahepatic portosystemic shunt revision, stent-graft was patent and the patient was asymptomatic at the 18-mo follow-up.
