This article explores the utilization of venovenous bypass (VVB) in liver transplantation (LT), highlighting its benefits, efficacy, and safety. Although VVB helps maintain hemodynamic stability and improve patient outcomes, its global use has declined due to concerns about heparinization, major bleeding, and the need for specialized expertise. Recent advancements in percutaneous cannulation techniques and extracorporeal technology have enhanced the safety of VVB. Studies show that VVB reduces the incidence of acute kidney injury, operative time, and blood loss without increasing morbidity or mortality. Despite these benefits, alternative techniques are being increasingly adopted. The article emphasizes the role of VVB in complex clinical scenarios and calls for continued research to optimize its application in liver transplantation.
