In recent years, percutaneous endovascular intervention has become the primary treatment for pediatric post-liver transplantation portal vein stenosis. This procedure is usually performed using a transhepatic approach. Herein, we report the transsplenic endovascular management of a 3-year-old girl with post-liver transplantation, late-onset portal vein occlusion, which occurred after repeated p...

Portal vein gas was once thought of as an invariably fatal condition. Now, with the availability of better equipment and expertise, the condition is more frequently diagnosed. A case of fever with rigors is presented and on ultrasound and CT examination was found to have portal venous gas which resolved with adequate antibiotic treatment. Blood culture revealed growth of gram negative bacillus;...

HCC has a high propensity to invade into the portal vein by direct venous extension or metastasis, which may cause tumor thrombosis that occurs in up to 70% of patients. It is well recognized that Portal Vein Tumor Thrombosis (PVTT) is a major detrimental prognosticator in HCC and almost all staging or prognostic systems for HCC include PVTT as an important parameter. Herein, we reported an int...

BACKGROUND Portal vein gas is an ominous radiological sign, which indicates a serious gastrointestinal problem in the majority of patients. Many causes have been identified and the most important was bowel ischemia and mesenteric vascular accident. The presentation of patients is varied and the diagnosis of the underlying problem depends mainly on the radiological findings and clinical signs. T...

OBJECTIVES To determine whether preoperative portal vein embolisation improves the operative outcome of patients undergoing extended right-sided hepatic resection for hepatobiliary malignancy. DESIGN Prospective non-randomised study. SETTING University teaching hospital, Hong Kong. PATIENTS Ninety-two patients underwent extended right-sided hepatic resection for hepatobiliary malignancy d...

In serial sagittal sections of a fetus on week 9 (crown-rump length, 36 mm), we incidentally found absence of the usual portal vein through the hepatoduodenal ligament. Instead, an anomalous portal vein originated behind the pancreatic body, crossed the lesser sac and merged with the upper part of the ductus venosus. During the course across the lesser sac, the vein provided a deep notch of the...

BACKGROUND Partial portal vein ligation causes an increase in portal pressure that remains stable even after the appearance of collateral circulation, with functional adaptation to prolonged decrease in portal blood flow. AIM To assess whether different constriction rates produced by partial ligation of the vein interfere with the results of this experimental model in rats. METHODS Three gr...
