Treatment of Cavernous Transformation of Portal Vein Caused by Hepatic Cystic Echinococcosis Using Ex Vivo Liver Resection and Autotransplantation

Background:Hepatic cystic echinococcosis (HCE) is a frequently overlooked parasitic liver disease, for which the commonly recommended treatment is radical resection.However, this approach is often associated with severe comorbidities such as HBV/HCV, cirrhosis, and hepatic carcinoma, among others. Case Report:In this report, we present a case successfully managed by ex vivo liver resection and autologous liver transplantation (ELRA).In the described case, ex vivo resection was not feasible due to recurrent lesions and infections invading the portal vein, which resulted in portal vein cavernous transformation. Conclusions:Through this paper, we aim to detail the treatment process, showcasing the feasibility and advantages of ELRA.Additionally, we propose a novel approach for the treatment of this disease, while emphasizing the importance of radical resection surgery to prevent long-term complications.
