Purpose: Aberrant hepatic artery anatomy is a considerable challenge during pancreatic surgery as it warrants extreme caution for the preservation of vascular supply as well as achievement of R0 resection margin.
Method: We reviewed the literature about the aberrant anatomical variations of the hepatic artery and its relevance during pancreatoduodenectomy and distal pancreatectomy.
Result: Preoperative deliberation of peri-pancreatic vascular anatomy using advanced imaging methods is crucial for surgeons. At the same time, intra-operative suspicion and early identification of aberrant anatomy may help to prevent vascular injury and related complications. Yet, vascular reconstruction may be needed in many situations; several techniques like pre-operative embolization provide new options for management in specific situations.
Conclusion: We have provided here an overview of the anatomical variants of the hepatic artery and their implication during pancreatoduodenectomy and distal pancreatectomy.

Background: The presence of hepatic steatosis (HS) is a crucial histological parameter for evaluating the suitability of liver transplantation. However, to date, no studies have used contrast-enhanced ultrasonography (CEUS) to diagnose and grade HS in brain-dead donors. This study aimed to detect and quantify hepatic microcirculatory perfusion in brain-dead donors using CEUS and to assess the utility of CEUS in the diagnosis and grading of HS.

Microscopic polyangiitis (MPA) affects small and medium vessel, which sometimes leads to arterial aneurysms. In English database, only 15 reports refer to ruptured aneurysms in MPA. We experienced a fatal case with MPA who developed multiple visceral aneurysms, resulting in rupture of the hepatic aneurysm.

Background: Population aging has led to a surge in elderly care needs worldwide. Bone aging, skeletal muscle degeneration, and osteoporosis pose critical health challenges for the elderly. The process of bone and skeletal muscle aging not only impacts the functional abilities but also increases fragility fracture risk.

Introduction: Liver retransplantation (reLT), which is the only treatment for liver graft failure, remains challenging not only because of its technical nature but also because it is performed in high-risk patients.
Methods: Nineteen patients who underwent reLT (second LT, n = 18; third LT, n = 1) between 1999 and 2021 were divided into two groups according to the graft laterality between prior transplantation and reLT (ipsilateral group, n = 9; contralateral group, n = 10). The aim of this study was to evaluate the short- and the long-term outcomes of patients who underwent living donor reLT and compared graft survival between ipsilateral and contralateral grafts.
