Orthotopic liver transplantation (OLT) in rats is technically feasible and useful for the assessment of clinical liver transplantation and analysis of inflammatory liver diseases. OLT in rats was pioneered by Lee et al. in 1973 using hand-suture techniques of all vessels. This model has not been widely used due to the long operative time and technical demand. The cuff method was introduced by K...

Hepatic tissue perfusion and O2 supply after ischemia are indispensable for recovery of cellular functions, but few studies have been performed regarding the recovery of tissue blood flow and O2 transport. After 5, 15, and 30 min of ischemia of rat livers, hepatic tissue perfusion, hepatic arterial and portal blood flow, plasma[Formula: see text], and O2 transport parameters were measured. Hepa...

OBJECTIVES To evaluate the in vivo efficacy of 915 MHz percutaneous coagulation in the treatment of hepatic artery injury. METHODS After inducing hepatic artery injury, 8 dogs in each group underwent 915 MHz microwave percutaneous coagulation therapy and 8 dogs were injected with batroxobin and α-cyanoacrylate. RESULTS The hemostatic effects of 915 MHz microwave were better than drug inject...

In recent years a considerable volume of work has been published on the relationship between portal venous blood-flow and hepatic artery pressure in cases of portal hypertension due to cirrhosis of the liver. As a result of this work, ligation of the hepatic artery has been carried out in the treatment of ascites and oesophageal varices, (Reinhoff, 195I; Berman 1951; Berman and Hull, 1952; Madd...

Gastrointestinal bleeding caused by peptic ulcer or portal hypertension is a serious complication in liver transplant recipients. However, Gastrointestinal bleeding from hepatic artery origin after liver transplantation is rare. We report duodenal massive bleeding secondary to erosion of hepatic artery after liver transplantation in two patients. This was diagnosed by angiography and treated su...

Hepatic artery pseudoaneurysms are a rare cause of upper gastrointestinal bleeding with a high mortality rate. We report a case of a 37-year-old woman who presented with massive gastrointestinal hemorrhage and was found to have an arterioenteric fistula from a hepatic artery pseudoaneurysm. Esophagogastroduodenoscopy revealed a 1.5-cm ulcer overlying a large mucosal bulge that compressed the lu...

RATIONALE Anatomical variations of the celiac trunk and the hepatic artery are of considerable importance in hepatopancreatobiliary surgery, liver transplants, and radiological abdominal interventions. PATIENT CONCERNS Here, we report a 57-year-old man with 2 weeks of painless progressive jaundice. Preoperative imaging and cytology brush results suggested an ampullary tumor and common hepatic...

Background: The incidence of anatomic variations of hepatic artery ranges from 20-50% in different series. Variations are especially important in the context of liver orthotopic transplantation, since, besides being an ideal opportunity for surgical anatomical study, their precise identification is crucial to the success of the procedure. Aim: To identify the anatomical variations in the hepa...
