Middle Hepatic Vein Tributary Reconstruction of a Right Hepatic Graft in Adult Living Donor Liver Transplantation: A Case Report.

In adult living donor (right liver) lobe transplantations (LDLT), the removal of the middle hepatic vein (MHV) with the graft and reconstruction carried out in the donor are of great importance. Here a 44-year-old male patient with hepatitis B-related end-stage liver failure is reported of whom his 34-year-old brother was evaluated as a donor candidate. At routine preoperative screening tests, neither the patient nor the donor candidate was found to have any pathological findings that might interfere with the transplantation. The donor candidate was assessed using multislice computed tomography for a standard liver volume measurement and anatomical structure evaluation and extended right hepatectomy including MHV was planned. MHV of the donor removed together with the graft was reconstructed to the common orifice of MHV-left hepatic vein using a cryopreserved aortic graft. In conclusion, if the MHV is removed with the graft in adult LDLT, appropriate reconstruction in the donor is also an important issue. Reconstruction carried out without creating tension and folding in the right hepatic vein is crucial for avoiding congestion and of great importance for the prevention of graft dysfunction.

Kidney Transplantation From Elderly Donor.

AIM: In recent years, there has been an increase in usage of grafts from advanced-age donors because of the shortage of organ availability. Acceptance of elderly living-kidney donors remains controversial due to the higher incidence of comorbidity and greater risk of postoperative complications. The objective of this study was to evaluate the graft function and patient survival using kidneys from living-related and unrelated donors who were older than 65 years of age. MATERIALS AND METHODS: From December 2008 until December 2013 we compared the outcomes of 294 patients (mean age, 47.67 ± 12.4 years; range, 16 to 74 years old) who received grafts from donors ≥ 65 years old to 2339 patients who received grafts from donors who were younger than 65 years old. RESULTS: We observed no significant differences in sex, time on dialysis, or cold ischemia time between the groups. The recipient ages between two groups were similar. For survival analysis we used the Kaplan-Meier survival estimator. Patient survival at 1, 2, and 3 years was 91.1%, 89.1%, and 88.5%, respectively, for patients transplanted with kidneys from donors ≥ 65-years-old vs 96.7%, 95.9%, and 95.0%, respectively, in the <65-year-old donor group. Multivariate analysis showed the variables associated with patient survival to be donor age at time of transplantation in years (hazard ratio [HR], 1.65; 95% confidence interval [CI], 1.59-1.71; P < .05), time on dialysis in months (HR, 1.22; 95% CI, 1.21-1.23; P = .002). Graft survival rates at 1, 2, and 3 years censored for death with functional graft at was 97.6%, 96.4%, and 94.1%, respectively, for patients transplanted with kidneys from donors older than 65 years vs 97.5%, 96.8%, and 95.2%, respectively, in the <65-year-old donor group. Multivariate analysis, HLA-DR mismatches (HR, 1.23; 95% CI, 1.12-1.55; P = .050), delayed graft function (HR, 1.77; 95% CI, 1.53-2.07; P = .021), and perhaps acute rejection (HR 1.14; 95% CI, 0.82-1.95; P = .093) were the variables associated with graft survival. CONCLUSION: We concluded that the use of kidneys from donors older than 65 years of age allows us to increase the rate of renal transplantation to approximately 15 to 20 per million population, with good graft and patient survivals provided that the protocol for expanded criteria organs ensured proper macroscopic and microscopic evaluation of the organ for transplantation.

Simultaneous Cardiac Surgery and Renal Transplantation Compared With Renal Transplantation After Cardiac Surgery.

Patients with end-stage renal disease (ESRD) have a high prevalence of coronary artery disease and cardiovascular death. The mortality and the morbidity rates of cardiac surgery are particularly high in these patients with end-stage renal disease. Performing cardiac surgery and kidney transplantation in the same session can reduce these complications in the early postoperative period by normalizing renal function. We compared the mortality and morbidity rates between patients who had undergone cardiac surgery and kidney transplantation separately and patients who had combined surgeries. This retrospective study consisted of 75 patients. One group of 60 patients underwent cardiac surgery and kidney transplantation in separate sessions, and the other group of 15 patients had combined surgeries in the same session, between March 2008 and September 2012. Patients who had combined surgeries achieved fluid electrolytic balance more easily, had shorter extubation times, used less blood and blood products, and had fewer major complications. The patients recovered faster and thus had shorter stays in the intensive care unit and hospital. This combined surgical approach allows normalized kidney function in patients with end-stage renal disease, so mortality and morbidity in the early postoperative period could be significantly reduced.

Renal Transplantation in Recipients Older Than 65 Years: Retrospective Analysis of the Results of a 4-year (2008-2012) Experience.

BACKGROUND: We analyze the results of renal transplantation among recipients older than 65 years old over a 4-year period (2008-2012) from a single renal transplantation unit and compare results with younger recipients. METHODS: We retrospectively analyzed the outcomes of 2018 renal transplantations performed between November 2008 and December 2012. The χ(2) test was used for the comparison of categorical data, and the Student t test was used for the analysis of continuous variables. Patient and graft cumulative actuarial survivals were calculated using the Kaplan-Meier analysis and we tested for differences with the Mantel-Cox log-rank test. RESULTS: Seventy-five (3.7%) recipients were aged ≥ 65 years with a median age of 68 (range, 65 to 82) years. Actuarial graft survivals at 1, 2, and 3 years were 93.8%, 92.5%, and 90.3%, respectively, for the <65 group and 89.7%, 88.1%, and 83.1%, respectively, for the ≥ 65 group (P < .03). Actuarial patient survivals at 1, 2, and 3 years were 96.3%, 95.5%, and 94.7%, respectively, for the younger and 91.8%, 90.2%, and 88%, respectively, for the older samples (P < .03). When graft survival was censored for patient death with a functioning kidney at 1, 2, and 3 years, the results were similar between groups with 95.5%, 94%, and 92.8%, respectively, for recipients aged <65 years and 94.7%, 89.2%, and 89.2%, respectively, for recipients aged ≥ 65 years (P = .213). CONCLUSIONS: Our results showed that renal transplantation in selected patients older than 65 years was associated with good outcomes; this indicates that it seems safe and effective to treat end-stage renal disease in the elderly knowing there are acceptable rates of graft and patient survival.
