Hepatic sinusoidal obstruction syndrome induced by tacrolimus following liver transplantation: Three case reports

Figure 1 Typical abdominal contrast-enhanced computed tomography features of hepatic sinusoidal obstruction syndrome after liver transplantation. A: Portal venous phase computed tomography (CT) on postoperative day (POD) 10 showed the blood flow of hepatic veins were fluent. No stenosis was observed at the vascular anastomosis of hepatic veins and suprahepatic inferior vena cava; B: Portal venous phase CT on POD 14 showed hepatic veins were obscured, while no stenosis was observed at the vascular anastomosis of suprahepatic inferior vena; C, D: Plain scan and arterial phases CT on POD 14 showed that liver parenchyma was heterogeneous low-density; E, F: Portal venous phase CT on POD 14 showed enlarged liver with patchy enhancement, massive ascites and unclear hepatic veins and these signs existed persistently to delayed phase.
