The efferent vessel of hepatocellular carcinoma (HCC) and the mechanism and pathogenesis of the high frequency of intrahepatic metastasis in HCC has not yet been clarified. Three hundred ninety-three resected specimens of HCC were examined for tumor thrombosis in the portal vein and the hepatic vein: 231 tumors < or = 5 cm in diameter were examined for the relationship between mode of tumor spr...
Portal vein aneurysm is a relatively uncommon entity. It is often an incidental, asymptomatic nding. With the increasing availability of advanced imaging modalities like Doppler ultrasound, computed tomography and magnetic resonance imaging, portal venous system aneurysms are being increasingly reported. We report two cases of intra hepatic portal vein aneurysm diagnosed incidentally on ultra-...
Portal vein aneurysm is rare, with incidence ranging from 0.06% to 0.43%. Serious complications include rupture, thrombosis, or compressive effects on nearby structures. Most cases in the literature have followed conservative treatment. Here we report case of a patient large asymptomatic portal that was surgically repaired. A 74-year-old man referred vascular surgery Computed tomography (CT) im...
BACKGROUND Liver transplantation in presence of diffuse portal vein thrombosis is possible by using caval blood as portal inflow, through cavo-portal transposition. However, clinical results are heterogeneous and experimental studies are needed, but similar hemodynamic conditions are difficult to obtain, especially in small animals. Herein we describe a new simple model of cavo-portal transposi...
Case summary A 9-month-old female neutered domestic shorthair cat presented with a history of episodic ptyalism, lethargy and abnormal behaviour. The clinical signs together with elevated pre- and post-prandial bile acid concentrations were consistent with hepatic encephalopathy (HE). In the absence of a portosystemic shunt (PSS) on abdominal ultrasound, medical management of HE was established...
Aims. To explore the effects and mechanisms of fluid shear stress on portal vein remodeling in a rat model of portal hypertension. Methods. Subcutaneous injections of CCl4 were given to establish a rat model of liver cirrhosis and portal hypertension. Biomechanical technology was adopted to determine the dynamic changes of haemodynamic indices and fluid shear stress. Nitric oxide (NO), synthase...
Portal vein thrombus has been detected in patients with liver cirrhosis, pancreatitis, ulcerative colitis, septicemia, myeloproliferative disorder, and neoplasm. The formation of portal tumor thrombus by hepatocellular carcinoma is well recognized, because of its high incidence, and subsequent development of portal hypertension such as rupture of varices, ascites and liver failure indicates the...
The purpose of this study was to define the relationship between arterial immunoreactive glucagon (IRG) and IRG that perfuses the liver via the portal vein during exercise in the diabetic state. Dogs underwent surgery >16 days before the experiment, at which time flow probes were implanted in the portal vein and the hepatic artery, and Silastic catheters were inserted in the carotid artery, por...
