- Patients undergoing orthotopic liver transplantation (OLT) have excessive blood loss during surgery that requires blood transfusions, leading to increased postoperative morbidity and mortality. We studied the efficacy and safety of activated recombinant factor VII (rFVIIa) in reducing transfusion requirements in OLT. This multicenter, randomized, double-blind, placebo-controlled trial enrolled patients undergoing OLT because of cirrhosis (Child-Turcotte-Pugh class B or C). Patients received a repeated intravenous bolus regimen of rFVIIa 60 or 120 microg/kg or placebo. The primary efficacy endpoint was the total number of red blood cell (RBC) units transfused during the perioperative period. A total of 182 patients were analyzed for efficacy and 183 for safety. No significant effect of rFVIIa was observed on the number of RBC units transfused or intraoperative blood loss compared with the placebo group. A significantly higher number of patients in the rFVIIa study groups avoided RBC transfusion. Administration of rFVIIa but not placebo restored the preoperative prolonged prothrombin time to normal value during surgery. Patients receiving rFVIIa and placebo did not experience a significant difference in rate of thromboembolic events. Additionally, there was no statistically significant effect of rFVIIa treatment on hospitalization rate, total surgery time, and the proportion of patients undergoing retransplantation. In conclusion, use of rFVIIa during OLT significantly reduced the number of patients requiring RBC transfusion. There was no increase in thromboembolic events with rFVIIa administration compared with placebo.

Hepatic venous outflow reconstruction in right live donor liver transplantation.
- 2005

Journal article (peer-reviewed)abstract
- The increasing experience with live donor liver transplantation has allowed for the identification of potential morbidities associated with technical considerations. Technical graft failure can be associated with both inflow and outflow vascular compromise. Although the latter has not always been given the relevance of the former, evidence pointing to its pivotal role continues to mount. We believe that impaired venous outflow was a cause of previously unexplained graft failures during our initial experience. Based on this observation, we developed a technique to prevent the "choking" of the graft at the outflow anastomosis with the inferior vena cava (IVC). The enhanced outflow via a cloaca maximum is achieved by reconstructing the graft vessels with preserved veins or arteries (usually iliac vessels are used) from a blood-group-identical or blood-group-compatible deceased organ donor. Alternatively, hepatic vein or portal vein obtained from the resected native liver can be used. The reconstructed common outflow is anastomosed to a triangular opening of the IVC. Such enhanced outflow provides optimal venous drainage, especially during the early phase of growth of the graft.

Liver transplantation for familial amyloidotic polyneuropathy : impact on Swedish patients' survival
- 2009

In: Liver transplantation. - : John Wiley & Sons. - 1527-6465 .- 1527-6473. ; 15:10, s. 1229-1235

Journal article (peer-reviewed)abstract
- Liver transplantation (LTx) for familial amyloidotic polyneuropathy (FAP) is an accepted treatment for this fatal disease. However, the long-term outcome with respect to that of nontransplanted patients has not been fully elucidated. The aim of this study was to compare the long-term survival of Swedish LTx FAP patients with that of historical controls, especially with respect to the age at onset of the disease and gender. In order to evaluate the outcome of LTx as a treatment for FAP, survival was calculated from the onset of disease. One hundred forty-one FAP patients, 108 transplanted and 33 not transplanted, were included in the study. Significantly increased survival was noted for LTx patients in comparison with controls. The outcome was especially favorable for those with an early onset of the disease (age at onset < 50 years) in comparison with early-onset controls (P < 0.001). In contrast, no significant difference for late-onset cases (> or = 50 years) was found. Transplanted late-onset females had significantly improved survival in comparison with transplanted late-onset males (P = 0.02). We were unable to find significant differences in survival between patients with long (> or = 7 years) or short (<7 years) disease duration at transplantation. The survival of male patients with late-onset disease appeared not to improve with LTx. LTx is an efficacious treatment for improving the survival of early-onset FAP patients. Further studies are needed to analyze the cause of the poorer outcome for late-onset male patients.

Orthotopic liver or multivisceral transplantation as treatment of metastatic neuroendocrine tumors
- 2007
-
In: Liver transplantation. - : Ovid Technologies (Wolters Kluwer Health). - 1527-6465 .- 1527-6473. ; 13:3, s. 327-33
-
Journal article (peer-reviewed)abstract
- Liver transplantation can be a therapeutic option for individual patients with neuroendocrine tumors metastatic only to the liver. In this consecutive series of 15 patients (5 multivisceral and 10 orthotopic liver transplantations) with well-differentiated carcinoids, or endocrine pancreatic tumors, we allowed higher proliferation rate (Ki67 <10%), large tumor burden, and higher age than previous studies. Liver transplantation offered good relief of symptoms, long disease-free intervals, and potential cure in individual patients. The survival of grafts and patients compared well with transplantation for benign disease. The overall 5-year survival was 90%. The recurrence-free survival of both multivisceral and liver transplantation related to the time after transplantation (about 20% at 5 years) despite inclusion of patients with higher risk. In conclusion, the critical prognosticators for long-term outcome still remain to be defined. The experience with multivisceral transplantation for patients with endocrine tumors of the pancreatic head is still limited.
