“…The most used imaging method for vascular assessment remains Doppler ultrasonography (US) [ 10 ]. This investigation can be performed immediately after liver transplantation, when other imaging techniques are not adequate [ 13 ]. Contrast ultrasound also has an important diagnostic role, allowing a better visualization of the vessels and differentiation between occlusion and stenosis of the hepatic artery [ 84 ].…”

“…Catheter angiography can be used when a hepatic artery abnormality is suspected, but not confirmed by US or CT examination [ 13 ]. The role of magnetic resonance imaging (MRI) in the diagnosis of vascular complications after liver transplantation is limited to patients with renal failure [ 13 ]…”

“…Vascular complications occur less frequently but are associated with high morbidity and mortality rates [ 10 , 11 ]. Currently, vascular complications represent the second most common cause of liver graft failure, after graft rejection, being associated with increased death rates [ 12 , 13 ]. Approximately 7% of patients with liver transplants from deceased donors and 13% of those with liver transplants from living donors have been documented to have vascular complications [ 2 , 13 , 14 , 15 ].…”

Biliary and Vascular Complications after Liver Transplantation–From Diagnosis to Treatment

The last decades have brought impressive advances in liver transplantation. As a result, there was a notable rise in the number of liver transplants globally. Advances in surgical techniques, immunosuppressive therapies and radiologically guided treatments have led to an improvement in the prognosis of these patients. However, the risk of complications remains significant, and the management of liver transplant patients requires multidisciplinary teams. The most frequent and severe complications are biliary and vascular complications. Compared to vascular complications, biliary complications have higher incidence rates but a better prognosis. The early diagnosis and selection of the optimal treatment are crucial to avoid the loss of the graft and even the death of the patient. The development of minimally invasive techniques prevents surgical reinterventions with their associated risks. Liver retransplantation remains the last therapeutic solution for graft dysfunction, one of the main problems, in this case, being the low number of donors.

“…The causes of both stenosis and thrombosis are typically technical in nature, but a patient's history of Budd-Chiari increases the risk of IVC/hepatic vein thrombosis postoperatively. 57 Basic diagnostic tools for diagnosing caval anastomosis complications include DUS and contrast-enhanced CT. A transjugular venogram with pressure gradient measurements is indicated for evaluating the upper caval anastomosis, providing additional access for simultaneous treatment. 50 Treatment requires immediate intervention and either revision of the anastomosis or urgent retransplantation.…”

Liver transplant patients require a multidisciplinary and personalized approach to optimize outcomes. Posttransplant complications can be devastating for the patient and can jeopardize graft survival. Therefore, a careful evaluation and stepwise decision-making process is necessary to determine the best strategy, whether it is surgical, interventional, or a combination of both. While access to liver transplant interventions in Latin America can be more limited compared with other parts of the world, many countries in the region have made significant progress in developing their liver transplant programs and improving the management of posttransplant complications. For example, in Brazil, specialized transplant centers and multidisciplinary teams have been established to reduce morbidity and improve graft survival rates. The article also explores the latest advancements in interventional radiology techniques, such as angioplasty, stent placement, and embolization, and how they can be used to successfully treat these complications. Overall, this article highlights the importance of a comprehensive approach to managing complications in liver transplant patients and emphasizes how individualized treatment plans can lead to improved outcomes, even in settings with limited resources.
