Management of Hepatic Artery Steno-Occlusive Complications After Liver Transplantation

Steno-occlusive disease (arterial obstructive disease) of the transplant hepatic artery is a collective term that can be used to include hepatic artery thrombosis, hepatic artery stenosis, and hepatic arterial kinks. The latter 2 can be referred to collectively as arterial anatomical defects. This chapter details the angiographic techniques and definitions required to make an accurate angiographic diagnosis of these arterial transplant complications. In addition, the chapter focuses on detailed technical aspects of the endoluminal management of these arterial complications. The chapter discusses the role and technical results of endoluminal management of these arterial complications and, when possible, the lesion morphologies most amenable to endoluminal management.
