The overall long-term survival rate of liver transplant patients is 70-75 %. During the early stages, the complications are vascular in nature, and in the later stages, biliary complications are major causes of morbidity. With the help of sonography, in particular with the addition of contrast enhanced ultrasound, a reliable diagnosis is possible. Despite this, in individual cases, other additional imaging methods should still be employed. The therapy should be used exclusively by interventional gastroentologists, radiologists or surgeons.
