pLTx is a highly complex procedure. It can only be performed safely by experienced teams. Starting a new pLTx program in a country with established centers must therefore avoid a learning curve. We have initiated a liver transplantation program for children in 2003. Medical standards were defined by a team of surgeons, pediatricians, radiologists, anesthesiologists, and pathologists before the first transplantation. An external expert in the field of pLTx supervised the whole process. In a pilot phase, six children weighing more than 20 kg were successfully transplanted. Following this series, the clinical pathways were re-evaluated, and the program was opened for children of all age groups. Between 2003 and 2008, 32 children received 34 organs. Sixty-eight percent of patients received a split-liver, 26% a full size organ, and 6% a reduced size graft. Four LRLTx were performed. Patient survival rate was 91%. We conclude that a new pLTx program can be established without a significant learning curve regarding mortality if a strict strategy of team-building is followed. In the pilot phase, small children and infants have to be referred and transplanted in an established center. An interdisciplinary team of specialists closely working together is the key for sustained success.

“…CEUS allows improved imaging of the portal venous perfusion in cases of unclear results. In addition, small portal venous branches can also be delineated using ultrasound contrast agent (3). A portal vein stenosis can be visualized by b-mode to detect a narrowing lumen of the portal vein with a post-stenotic dilatation as well as an aliasing phenomenon verified by color Doppler (Fig.…”

“…In addition to vascular complications another important group of postoperative complications after liver transplantation is organ rejection. A total of 30-80% of patients experience acute rejection within the first 2 weeks (3,49). Cellular rejection is diagnosed by a biopsy and humeral rejection by detection of donor specific HLA antibodies.…”

“…Despite technical and perioperative improvements, the surgical procedure is still associated with a significant number of vascular and non-vascular complications. Vascular complications most commonly appear during the first 3 weeks post transplantation (1)(2)(3)(4). During the first few days after the operation, routine ultrasound as a fast and radiation-free method allows an early and selective identification of possible pathological abnormalities and postoperative graft complications.…”

Clinical application of modern ultrasound techniques after liver transplantation

et al. 2016

Liver transplantation has been established as a first-line therapy for a number of indications. Conventional ultrasound and contrast-enhanced ultrasound (CEUS) are methods of choice during the postoperative period as a safe and fast tool to detect potential complications and to enable early intervention if necessary. CEUS increases diagnostic quality and is an appropriate procedure for the examination of vessels and possibly bile ducts. This article presents the state of the art of ultrasound application during the early period after liver transplantation. It addresses common vascular complications and describes the identification of postoperative abnormal findings using ultrasound and CEUS.

A study was performed to determine the visualization of the transjugular intrahepatic portosystemic stent shunt (TIPSS) and the detection of stenosis by the use of a capillary transversing signal enhancer. In 37 patients 37 colour-coded duplex sonographies were performed before and after intravenous injection of the ultrasound signal enhancer Levovist (Schering, Berlin). The examinations were evaluated using a four-category score. Special attention was paid to the detection of stenoses in the TIPSS. Transjugular portal venograms of the same day were used as gold standard. The use of Levovist provided better colour and flow signals for the portal vein end of the shunt in only 9 of 37 sonograms and for the hepatic vein end of the shunt in 37 of 39 sonograms. Eleven of 13 stenoses requiring reintervention in portal venography could be correctly identified with signal enhancer. Eleven of these 13 stenoses were located in the hepatic vein end of the shunt. Ultrasound signal enhancer can significantly improve the sonomorphological visualization especially of the hepatic vein end of TIPSS in colour-coded duplex sonography. Stenoses which usually occur in the hepatic vein end of the shunt may be better detected.
