S3265 A Case of Portal Vein Thrombosis Following COVID Vaccination

Abstract

Discussion: Despite being mainly thought of as a chronic condition, AIH can manifest acutely as demonstrated by our case. In one study, of 142 cases of acute liver failure that were originally labeled as "acute liver failure of indeterminate etiology", 34 of them were found to be caused by AIH upon further investigation. This case demonstrates the importance of considering autoimmune hepatitis as a possible etiology of acute liver failure. Overlooking autoimmune hepatitis as a cause of acute liver failure may cause delays in treatment and obtaining a liver transplant.
