The role of endovascular and endobiliary methods in the treatment of post-liver transplant complications

Liver transplantation is the treatment of choice for patients with end-stage liver disease or acute liver failure. However, vascular complications, such as hepatic artery stenosis and/or thrombosis, graft portal vein stenosis and biliodigestive strictures following liver transplantation are still common despite improvements and innovations in surgical techniques. These complications can lead to graft damage or even death, and they are caused by many factors. Although minimally invasive interventional radiology is an optional treatment for such post-liver transplant complications, there is little research on this method of treatment.
