Factors of complexity. a Oblique axial CT (fused portal venous phase and venous phase) shows an intervening caudate lobe (PSSS procedure: portacaval end-to-side with subsegmental liver resection); bold arrow: caudate lobe; arrowhead: portal vein; small arrow: hepatic artery; asterisk: IVC. b Axial CT with partial thrombosis of the extrahepatic portal vein (PSSS procedure: portacaval side-to-side after thrombectomy). c Oblique coronal CT MIP shows a large distance of 29 mm between IVC (small arrow) and superior mesenteric vein (arrowhead). In this patient, an allograft was interposed as seen in d (PSSS procedure: mesocaval with graft interposition). d Postoperative oblique coronal CT MIP reconstruction shows the interposed graft (bold arrow) connecting the SMV (arrowhead) and IVC (small arrow)
