- Innovative Technique Avoiding Bleeding After Reperfusion in Living Donor Liver Transplant Using a Modified Right Lobe Graft(2022) PINHEIRO, Rafael S.; ANDRAUS, Wellington; FORTUNATO, Allana C.; FERNANDES, Michel Ribeiro; NACIF, Lucas Souto; MARTINO, Rodrigo Bronze De; DUCATTI, Liliana; WAISBERG, Daniel Reis; ARANTES, Rubens Macedo; ROCHA-SANTOS, Vinicius; GALVAO, Flavio Henrique Ferreira; CARNEIRO-D'ALBUQUERQUE, Luiz AugustoBackground. Living donor liver transplant (LDLT) is a valuable therapeutic option for over-coming the deceased donor shortage. Modified right lobe graft (MRLG) keeps the middle hepatic vein (MHV) trunk with the remnant liver to improve donor safety. Hemostasis in the MHV tributary reconstruction can be tricky; surgical stitches and energy coagulation are ineffective. Fibrin glues are excellent vascular sealants but are poor in maintaining hemostasis in an active hemorrhage or preventing resection surface-related complications after liver resection. We propose applying fibrin sealant during back table graft preparation to seal the hepatic edge and MHV reconstruction to avoid bleeding after graft revascularization. Methods. Our retrospective cohort study included all adult patients undergoing LDLT between August 2017 and December 2021. During the back table procedure, we performed the reconstruction of the inferior right hepatic vein and/or MHV tributaries from segment 5 (V5) and segment 8 (V8) using a vein harvested from a nonrelated deceased donor. Before initiating the hepatic graft implantation, we applied fibrin sealant in the resected parenchyma, especially in the V5 and V8 anastomosis, to seal the hepatic edge and hepatic vein reconstruction. Results. No bleeding was identified in the hepatic edge, and blood product transfusion was unnecessary for any recipients after reperfusion. Conclusion. In LDLT using MRLG with MHV reconstruction, the fibrin sealant, when applied on the raw hepatic surface, and vascular reconstruction during back table graft preparation avoided bleeding after graft revascularization.

Basic science should not be neglected because the translation from basic research is not sustained in the absence of basic research. The purpose of this literature review was to analyze the translational medicine in the liver transplant field: liver ischemia-reperfusion injury (IRI), immunosuppression, clinical and surgical complications, small-for-size syndrome (SFSS), rejection, and ongoing innovations (liver machine, liver preservation, artificial livers, and regenerative medicine). We performed a systematic literature review that were updated in October 2016. The searches were performed in the Cochrane Central Register of Controlled Trials and Review, PubMed/Medline, Embase, and LILACS databases. All the selected studies on the management of translational medical research in liver transplantation (LT) were analyzed. Initially the search found 773 articles. Methodological viewing and analysis of the articles, followed by the application of scientific models, including translational medicine in the liver transplant field. In conclusions, this review demonstrates the application of scientific research with translation medical benefits regarding the LT. The literature has a great tendency, improvements and investments in the study of translational medicine in LT. Innovative studies and technologies from basic science help to clarify clinical doubts. Moreover, evidence increases the importance of scientific research in quality of clinical practice care.
conferenceObject Elastography for the Diagnosis and Graduation of Liver Disease in Patients with Long Term Parenteral Nutrition(2021) GALVAO, F.; VEZOZZO, D.; LEE, A.; WAISBERG, D.; ROCHA, M.; NACIF, L.; PINHEIRO, R.; FIGUEIRA, E.; CASSENOTE, A.; CARRILHO, F.; WAITZBERG, D.; CARNEIRO-D'ALBUQUERQUE, L.- Living-donor liver transplantation in Budd-Chiari syndrome with inferior vena cava complete thrombosis: A case report and review of the literature(2021) ROCHA-SANTOS, Vinicius; WAISBERG, Daniel Reis; PINHEIRO, Rafael Soares; NACIF, Lucas Souto; ARANTES, Rubens Macedo; DUCATTI, Liliana; MARTINO, Rodrigo Bronze; HADDAD, Luciana Bertocco; GALVAO, Flavio Henrique; ANDRAUS, Wellington; CARNEIRO-D'ALBURQUERQUE, Luiz AugustoBACKGROUND 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. CASE SUMMARY A 35-year-old male patient with liver cirrhosis due to BCS and hepatocellular carcinoma beyond the Milan criteria underwent living-donor LT with IVC reconstruction. It was necessary to remove the IVC as its retrohepatic portion was completely thrombosed, up to almost the right atrium. A right-lobe graft was retrieved from his sister, with outflow reconstruction including the right hepatic vein and the branches of segment V and VIII to the middle hepatic vein. Owing to massive subcutaneous collaterals in the abdominal wall, venovenous bypass was implemented before incising the skin. The right atrium was reached via a transdiaphragramatic approach. Hepatectomy was performed en bloc with the retrohepatic vena cava. It was reconstructed with an infra-hepatic vena cava graft obtained from a deceased donor. The patient remains well on outpatient clinic follow-up 25 mo after the procedure, under an anticoagulation protocol with warfarin. CONCLUSION Living-donor LT in BCS with IVC thrombosis is feasible using a meticulous surgical technique and tailored strategies.
