Prevention and treatment of rethrombosis after liver transplantation with an implantable pump of the portal vein

Zhengrong Shi, Lunan Yan, Jichun Zhao, Bo Li, Tianfu Wen, Mingqing Xu, Wentao Wang, Zheyu Chen, Jiaying Yang – 5 March 2010 – Implantable pumps have been used to prevent deep vein thrombosis and other diseases. In this article, we report for the first time the prevention and treatment of rethrombosis of the portal vein in liver transplantation with an implantable pump of the portal vein.

Portal hyperperfusion: Mechanism of injury and stimulus for regeneration in porcine small‐for‐size transplantation

Constantino Fondevila, Amelia J. Hessheimer, Pilar Taurá, Olga Sánchez, David Calatayud, Nicolas de Riva, Javier Muñoz, Jose Fuster, Antoni Rimola, Juan C. García‐Valdecasas – 5 March 2010 – Understanding the pathogenesis of small‐for‐size (SFS) syndrome is critical to expanding the applicability of partial liver transplantation. We aimed to characterize its acute presentation and association with alterations in hepatic hemodynamics, microstructure, and regeneration in a porcine model. Eighteen SFS liver transplants were performed. Donors underwent 70% hepatectomy.

Human leukocyte antigen crossmatch testing is important for liver retransplantation

Angeline Goh, Mario Scalamogna, Tullia De Feo, Francesca Poli, Paul I. Terasaki – 5 March 2010 – Although human leukocyte antigen (HLA) crossmatching is often thought to be unnecessary for liver transplants (LTs), we provide evidence that for retransplants, it is essential. Sera from 139 retransplant patients who had received livers from deceased donors were retrospectively analyzed with single antigen beads on a Luminex platform for HLA antibodies.

Contrast‐enhanced ultrasound for the evaluation of hepatic artery stenosis after liver transplantation: potential role in changing the clinical algorithm

Rong‐Qin Zheng, Ren Mao, Jie Ren, Er‐Jiao Xu, Mei Liao, Ping Wang, Min‐Qiang Lu, Yang Yang, Chang‐Jie Cai, Gui‐Hua Chen – 1 March 2010 – Hepatic artery stenosis (HAS) is a common complication in liver transplant patients. Conventional angiography remains the gold standard for diagnosis. Recently, contrast‐enhanced ultrasound (CEUS) has begun providing real‐time angiographic‐like images of vessels and allowing the accurate diagnosis of arterial diseases such as hepatic artery thrombosis.
