Objectives: Our objective was to evaluate the incidence of renal replacement therapy after orthotopic liver transplant and to evaluate and analyze patient outcomes. Materials and Methods: We performed a retrospective analysis of 177 consecutive patients at a tertiary care unit who underwent orthotopic liver transplant between January 2010 and June 2016. Patients who were admitted to the intensive care unit after orthotopic liver transplant and who required renal replacement therapy were included. Results: A total of 177 (79 adult, 98 pediatric) orthotopic liver transplants were performed during the study period. Of these, 35 patients (19%) required renal replacement therapy during the early posttrans plantation period. After excluding 5 patients with previous chronic renal failure, 30 patients (17%; 20 adult [25%], 10 pediatric [10%]) with acute kidney injury required renal replacement therapy. The mean patient age was 31.1 +/- 20.0 years, with a mean Model for End-stage Liver Disease score of 16.7 +/- 12.3. Of the patients with acute kidney injury who underwent renal replacement therapy, in-hospital mortality was 23.3% (7 of 30 patients), and 40% remained on dialysis. No significant difference was seen in mortality between early versus delayed initiation of renal replacement therapy in patients with stage 3 acute kidney injury (P = .17). Conclusions: Of liver transplant recipients who present with acute kidney injury, 19% require renal replacement therapy, and in-hospital mortality is 20% in the early postoperative period.

Venoarterial Extracorporeal Membrane Oxygenation Support as a Bridge to Heart Transplant: Report of 3 Cases
(2016) Gedik, Ender; Ulas, Aydin; Ersoy, Ozgur; Atar, Funda; Firat, Aynur Camkiran; Pirat, Arash; 0000-0002-7175-207X; 0000-0002-8130-9901; 0000-0003-1470-7501; 27805530; ABI-2971-2020
Heart transplant is the only definitive treatment of end-stage heart failure. Venoarterial extracorporeal membrane oxygenation may be used as a bridge to heart transplant. Among 31 patients who underwent heart transplant between January 2014 and June 2016, we present our experiences with 3 patients who received venoarterial extracorporeal support as a bridge to heart transplant. The first patient was a 51-year-old male with ischemic dilated cardio myopathy. Transplant was performed after 6 days of extracorporeal support, and the patient was discharged and alive at follow-up. Patient 2 was a 12-year-old girl with dilated cardiomyopathy who presented with cardiac arrest. Extracorporeal support was initiated during cardiopulmonary resuscitation. She had full neurologic recovery and remained on the wait list. She received a transplant 22 days after resuscitation. She survived and was alive at day 220 posttransplant. The third patient was a 50-year-old male with ischemic dilated cardiomyopathy requiring venoarterial extracorporeal support. Percutaneous balloon atrial septostomy was performed for left ventricle venting. He underwent transplant on day 28 after intensive care unit admission. He died 29 days after release from the hospital. Regarding patients on heart transplant wait lists who are worsening despite optimal medical therapy, venoarterial extracorporeal membrane oxygenation support is a safe and viable last resort.
