Simultaneous Liver-Kidney Transplantation and the Use of Intraoperative Dialysis: A Monocenter Study

Hyperkalemia in liver transplantation

Hyperkalemia commonly occurs in patients undergoing liver transplantation. The intraoperative course of liver transplant often involves hemodynamic and metabolic derangements leading up to liver reperfusion. Potassium levels can rise to dangerous levels immediately after reperfusion. The consequences of intraoperative hyperkalemia include risk of malignant arrhythmias and cardiac arrest. This review explores the numerous causes of hyperkalemia, including contributing surgical and anesthetic factors. The authors also discuss various treatment options and surgical techniques to manage perioperative hyperkalemia. It is important for anesthesiologists to understand the implications and management of hyperkalemia to optimize patients and reduce the risk of an intraoperative cardiac arrest.

Outcomes of Combined Liver-Kidney Transplantation - Single Center Experience

BACKGROUND

There is continuous growth of combined liver-kidney transplantation (CLKTx) numbers with remarkable outcomes, especially among patient with liver cirrhosis and end-stage renal disease. The aim was to present a single center experience.

METHODS

Twenty patients (9 males) with a mean age of 48 (range: 20-62) years underwent CLKTx from 2005 to 2022. Indications were polycystic liver and kidney diseases (ADPKD) in 12 cases, cirrhosis due to hepatitis (4 patients), and 1 case of amyloidosis, alcoholic liver disease, nonalcoholic steatosis, and congenital hepatic fibrosis with concomitant glomerulonephritis. After hepatectomy, half of the patients had orthotopic liver transplantation with piggy-back technique, and the other had conventional technique. All but 1 recipient had biliary end-to-end anastomosis. 3 patients had preemptive kidney graft transplantation. 4 underwent simultaneous right-side nephrectomy due to volume of the right kidney. Kidney was transplanted from the separate incision after abdominal closure with typical anastomoses. Tacrolimus, mycophenolate mofetile, basiliximab, and steroids were applied for all recipients.

RESULTS

Mean follow-up was 57.7 ± 54 months. No primary non-function of the grafts occurred. Delayed kidney graft function (DGF) occurred in 8 patients. Three-month, 1-year, and 5-year cumulative survival rates were: 90%, 80%, and 72% respectively. None of the patients required retransplantation, and 1 recipient returned to hemodialysis 19 months after transplantation. Preemptive kidney transplantation and simultaneous right-side nephrectomy were not significant for DGF and recipient survival. No deaths within the first year occurred in piggy-back technique.

CONCLUSIONS

CLKTx is safe and effective in the treatment of both liver and kidney failure.
