- important complication of stem cell transplantation (SCT)
- aka sinusoidal obstruction syndrome (SOS)
- mortality >30%
- usually caused by the preparatory regimen given before SCT e.g. busulfan
- also seen in liver transplantation
- most likely a lesion of the sinusoidal endothelial cells of hepatic venules
- venule occlusion is not an essential feature
- weight gain
- abdominal distention
- right upper quadrant pain
- elevated total and direct bilirubin levels
- diagnostic ultrasound finding is a reversal of flow in the portal and hepatic veins (this may not be seen early); hepatic congestion and elevated subhepatic and portal vein pressures
- supportive care and monitoring
- Fluid restriction
- TIPS procedure for refractory ascites
- Unproven experimental treatments: thrombolytics, defibrotide (single-stranded polyribonucleotide with antithrombotic, thrombolytic, anti-ischemic and anti-inflammatory properties)
