•Pre-operative CTA: PVT, anatomic variations, celiac stenosis,size of splenic artery, size of varices (spleno-renal
•Talk to surgeons
–Unusual anastomoses and donor anatomy
•Do not have tunnel vision and only do liver images withDoppler. Measure spleen, look for varices, celiac stenosis
•Combinations of complications may occur
•Use gray scale images, especially for signs of ischemicliver parenchyma or bile ducts
–Sludge in bile ducts may be isoechoic or just slightly moreechogenic than liver, may see isolated areas of biliary dilatation
•If high index of suspicion for vascular complication andUS negative, get CTA, MRA or catheter angiography
