About

Adam Griesemer, MD, is an associate professor in the Department of Surgery at NYU Grossman School of Medicine and serves as the surgical director of the Pediatric Transplant Surgical Program and the Living Donor Liver Transplant Program at NYU Langone Health. His research interests include the immune response after liver transplantation and xenotransplantation using genetically modified organs from nonhuman sources, supported by the National Institutes of Health. He has received awards from the American Association for the Study of Liver Diseases, the American Society of Transplant Surgeons, the American Society of Transplantation, and the International Xenotransplantation Association, including the Rising Star in Transplantation Surgery Award. Dr. Griesemer's clinical work focuses on pediatric and adult liver transplantation, managing conditions such as cirrhosis, hepatitis, bile duct abnormalities, and liver cancers. He specializes in living donor transplantation, utilizing minimally invasive surgical techniques to reduce discomfort and recovery times for donors, and performs complex surgeries to treat life-threatening conditions in children, often addressing congenital issues like bile duct defects, enzyme abnormalities, or autoimmune disorders. He emphasizes a holistic approach, recognizing the emotional needs of families and working with a multidisciplinary team to provide evidence-based care. His surgical expertise extends to procedures for managing liver cancer and…

  We present a case of COVID-19 hepatitis in a living donor liver allograft recipient whose donor subsequently tested positive for COVID-19. The patient is a female infant with biliary atresia (failed Kasai procedure). She recovered well, with improving liver function tests for 4 days. On post-operative day (POD) 4 the patient developed respiratory distress and fever. COVID-19 testing (polymerase chain reaction) was positive. Liver function tests increased approximately 5-fold. Liver biopsy showed…

• Living donor liver transplant candidate and donor selection and engagement: Meeting report from the living donor liver transplant consensus conference

  Clinical Transplantation · 2023 · 20 citations

  INTRODUCTION: Living donor liver transplantation (LDLT) is a promising option for mitigating the deceased donor organ shortage and reducing waitlist mortality. Despite excellent outcomes and data supporting expanding candidate indications for LDLT, broader uptake throughout the United States has yet to occur. METHODS: In response to this, the American Society of Transplantation hosted a virtual consensus conference (October 18-19, 2021), bringing together relevant experts with the aim of identif…
