Although the interruption of the hepatic arterial flow usually is well tolerated, this is not always the case, and it is important to predict in which circumstances complications are likely to occur. The main determinants that should guide the surgeon confronted with this problem are (1) whether the portal circulation is normal, (2) whether structures carrying collateral blood supply have been interrupted, and (3) whether some form of biliary reconstruction is needed. We present our experience with three patients in whom the hepatic artery was damaged at operation as examples of how this injury can be dealt with in practice and discuss the measures to prevent or treat the complications that developed.

Arterial Reconstruction Using the Right Gastroepiploic Artery in Living Donor Liver Transplantation: A Single-Center Experience.

Department of Surgery, Nagasaki University Graduate School of Biomedical Sciences, Nagasaki, Japan.
BACKGROUND Recipient hepatic arteries are generally used for arterial reconstructions in living donor liver transplantation. When the hepatic arteries are not feasible, the right gastroepiploic artery is one of the options for arterial reconstructions. In this study, we evaluate the feasibility of using the right gastroepiploic artery and report the analyzed retrospective patient outcomes.

A 77-year-old male presented for an incidental 5-cm gastroduodenal artery aneurysm (GDAA). He underwent an endovascular GDAA coil embolization with 6 months of no aneurysmal growth on surveillance imaging. His 12-month scan revealed aneurysmal growth from 5 cm to 7.

Background: In living donor liver transplantation (LDLT), maintaining hepatic arterial flow is critical for graft survival. Alternative methods are required when the recipient's hepatic artery is unsuitable due to extensive dissection or inadequate flow. This study evaluates the efficacy and safety of splenic artery transposition (SAT) for hepatic arterial reconstruction in LDLT.

Introduction: The duodeno-pancreatic region is a highly vascularized area. The superior and posterior pancreaticoduodenal artery is a vessel primarily originating from the gastroduodenal artery. It exhibits rare anatomical variations, such as its emergence from the right branch of the hepatic artery, which we fortuitously identified during a cadaver dissection.

Background: Pyroptosis is closely associated with chemotherapeutic drugs and immune response. Here, we investigated whether oxaliplatin, a key drug in FOLFOX-hepatic artery infusion chemotherapy (FOLFOX-HAIC), induces pyroptosis in hepatoma cells and enhances antitumor immunity after tumor cell death.
Methods: Hepatoma cells were treated with oxaliplatin.
