Analysis of two reperfusion techniques in uterine transplantation in an experimental model.

Introduction: Uterine transplantation was developed for the treatment of absolute uterine factor infertility. As it is a new modality of transplantation, there is still room for technical improvement. A factor that impacts graft survival in organ transplantation is the warm ischemia time.

En Bloc Simultaneous Liver-Kidney Transplantation Compared to the Traditional Technique: Results From a Single Center.

Background: Simultaneous liver-kidney transplantation is indicated for patients with concomitant end-stage liver disease and end-stage renal disease. The traditional technique involves separate implantations of the liver and the kidney. In the en bloc approach, the liver is recovered en bloc with the right kidney and the donor renal artery is anastomosed to the donor splenic artery.

Liver Transplantation for Adenomatosis: A Single-Center Experience.

Background: Liver adenomatosis is characterized by multiple adenomas diffusely distributed throughout the liver parenchyma. Studies addressing liver transplantation for those cases are scarce, and the criteria used to indicate transplantation are still debatable.

Objective: To report a single-center experience of liver transplantation for diffuse adenomatosis.

Retransplantation for Late Hepatic Artery Thrombosis: Results from a Single Center.

Background: Hepatic artery thrombosis is the most common vascular complication of liver transplantation. When occurring late in the postoperative course, it may have no clinical repercussions, and conservative treatment may be implemented. Some patients, however, will develop severe biliary complications due to ischemic cholangiopathy and require retransplantation.

Liver Transplantation for Benign Massive Hepatomegaly: Results From a Single Center and Contribution of the Left-to-Right Piggyback Approach.

Introduction: Polycystic liver disease and giant hepatic hemangioma may present with severe symptom burden and indicate orthotopic liver transplantation. The left-to-right piggyback approach is a useful technique for performing total hepatectomy of enlarged livers.

Objective: The purpose of this study is to analyze the results of liver transplantation in patients with benign massive hepatomegaly.

COVID-19 Pandemic Impact on Liver Donation in the Largest Brazilian Transplantation Center.

Background: COVID-19 has spread worldwide and has become a public health emergency and a pandemic of international concern. The solid organ donation system was no different. This study aimed to investigate the effect of COVID-19 on the liver transplant (LT) system in Brazilian territory.

Septuagenarian Donors and Recipients in Deceased Donor Liver Transplantation: A Brazilian Single Center Experience and Literature Review.

Background: The number of elderly patients who have end-stage liver disease and require liver transplantation has dramatically increased. On the other hand, liver grafts from elderly donors have been offered more frequently for transplantation. The present study aims to analyze the results of liver transplants performed with donors and recipients aged ≥70 years.

Hepatic Venous Outflow Obstruction in Adult Deceased Donor Liver Transplantation: Classic Piggyback Implantation Versus a Modified Technique that Widens the Ostium of the Recipient's Left and Middle Hepatic Veins.

Background: The classic piggyback technique uses the union of the 3 hepatic veins to perform the cavo-caval anastomosis. However, due to the lateral localization of the right hepatic vein, the partial clamping of the vena cava in this technique significantly reduces the venous return to the right atrium. To avoid this, we adopted in 2015 a modified piggyback technique, in which we use the common trunk of the middle and left hepatic veins and also perform a lateral incision toward the right in the anterior wall of the vena cava in order to widen the final ostium of the cavo-caval anastomosis.

Incidence of Donor Hepatic Artery Thrombosis in Liver Grafts Recognized During Organ Procurement and Backtable: A Rare but Treacherous Pitfall In Liver Transplantation.

Introduction: Donor hepatic artery thrombosis (dHAT) identified during liver procurement and backtable is a rare and little-reported event that can make liver transplants unfeasible.

Methods: This is a retrospective study of dHAT identified during liver grafts procurements or backtable procedures. All grafts were recovered from brain-dead donors.

Pancreas Transplantation in a Single Center: Risk Factors Associated With Pancreatic Allograft Thrombosis.

Background: Pancreas transplantation remains a challenging procedure for small and medium-sized transplants teams, despite improvements in graft survival. Data regarding the impact of the procurement team's experience on the outcomes of pancreas transplant are lacking. The objective of this study was to evaluate risk factors that lead to pancreatic allograft thrombosis, especially the experience of the pancreas procurement team.

Attitude and knowledge of medical students toward donation after circulatory death.

Objective: A survey among medical students in a Brazilian public university was performed to investigate the acceptance of organ donation in Brazil, particularly donation after circulatory death (DCD).

Methods: A questionnaire including 26 objectives and Likert scale questions was validated and sent to all medical students of our institution. The answers were analyzed considering the whole set of individuals as well as by dividing the medical students into two groups: less graduated students and more graduated students.

Living-donor liver transplantation in Budd-Chiari syndrome with inferior vena cava complete thrombosis: A case report and review of the literature.

Background: Budd-Chiari syndrome (BCS) is a challenging indication for liver transplantation (LT) due to a combination of massive liver, increased bleeding, retroperitoneal fibrosis and frequently presents with stenosis of the inferior vena cava (IVC). Occasionally, it may be totally thrombosed, increasing the complexity of the procedure, as it should also be resected. The challenge is even greater when performing living-donor LT as the graft does not contain the retrohepatic IVC; thus, it may be necessary to reconstruct it.

Liver transplant recipients infected with SARS-CoV-2 in the early postoperative period: Lessons from a single center in the epicenter of the pandemic.

The impact of coronavirus disease-19 (COVID-19) in liver recipients remains largely unknown. Most data derive from small retrospective series of patients transplanted years ago. We aimed to report a single-center case series of five consecutive patients in the early postoperative period of deceased-donor liver transplantation who developed nosocomial COVID-19.

Feasibility of Large Liver Grafts in Adults.

Introduction: Size mismatch between donor and recipients may negatively influence postoperative results of liver transplantation (LT). In deceased donor LT for adults, large grafts are occasionally rejected due to the fear of primary nonfunction. The aim of this study is to assess the feasibility of using large liver grafts in adults undergoing deceased donor LT.
