In liver resection operations the Pringle (Baron) maneuver can be used for temporary ischemia by clamping the hepatoduodenal ligament intermittently. In this beagle canine model we investigated whether hemorheological parameters may alter in systemic, portal and hepatic venous blood and in arterial samples during-after Pringle maneuvers. In Pringle Group unilateral ...

Portal vein thrombosis (PVT) can be a difficult clinical problem to assess and manage. A high index of suspicion is needed for a PVT diagnosis given the subtle presentation and potentially serious long-term complications. It should be considered a clue to the presence of one or several underlying disorders, including ...

Recurrent venous thrombosis following liver transplantation for Budd-Chiari syndrome is common, particularly in the setting of an underlying myeloproliferative disorder. We describe a patient who developed refractory ascites due to portal vein thrombosis following liver transplantation for Budd-Chiari syndrome in the setting of paroxysmal nocturnal hemoglobinuria. Extensive portal vein thrombosis, ...

A hyperdynamic splanchnic and systemic circulation is typical of cirrhotic patients and has been observed in all experimental forms of portal hypertension. The hyperdynamic circulation is most likely initiated by arterial vasodilatation, leading to central hypovolemia, sodium retention, and an increased intravascular volume. Arterial vasodilatation is regulated by a complex ...

BACKGROUND AND AIM: Congenital portosystemic veno-venous malformations are rare abnomalities that often remain undiagnosed. Typically they are classified by their anatomical characteristics according to Morgan (extrahepatic, Abernethy malformations type Ia,b and II) and Park (intrahepatic, types 1-4). However, their clinical presentation is less dependent on the anatomical type. METHOD: We ...

Cavernous transformation of the portal vein (portal cavernoma) consists of a periportal or/and intrahepatic venous collateral network, developed as a result of acute or long-standing portal vein thrombosis. Better control of hemorrhagic and thrombotic complications in the patients with portal cavernoma substantially improves their life span and the clinical outcome. ...

BACKGROUND: Arterio-portal fistulas (APFs) are rare vascular disorders of various origins that can lead to severe portal hypertension. Even if surgery was initially the treatment of choice, more recently, interventional radiological procedures have been considered as the first line therapeutic option. CASE REPORT: A man with no history of liver ...

Terminal liver cirrhosis is associated with marked severe portal hypertension, which increases the risk of intraoperative hemorrhage and graft hyper-perfusion, especially, in small-for-size graft. In cases with developed collateral vessels, we often face difficulties in perihepatic dissection with blood stanching against bleeding during recipient hepatectomy. For aseptic preoperative portal decompression, ...

Vascular abnormalities associated with acute pancreatitis are well-known and reported in the literature in up to 50% of the patients with acute necrotizing pancreatitis. Most reported vascular abnormalities are superior mesenteric and/or portal vein thromboses and arterial pseudo-aneurysms. Portal vein aneurysm and/or spleno-mesenteric venous aneurysm are rare entities. Furthermore, portal ...

Vessel embolization can be a valuable adjunct procedure in transjugular intrahepatic portosystemic shunt (TIPS). During the creation of a TIPS, embolization of portal vein collaterals supplying esophageal varices may lower the risk of secondary rebleeding. And after creation of a TIPS, closure of the TIPS itself may be indicated if ...

Mirror image transposition of abdominal and thoracic viscera is termed situs inversus. Duodenal obstruction in situs inversus is rare. A preduodenal portal vein, though not uncommon in situs inversus, rarely causes duodenal obstruction. Where obstruction by a preduodenal portal vein is diagnosed, a duodeno-duodenostomy is the recommended treatment. A duodenal ...

Invasion to the celiac axis and portal vein is one reason for the unresectability of pancreatic carcinoma of the body and tail. Some authors advocate a radical distal pancreatectomy with en-bloc resection of the celiac artery and portal vein. However, long-term survival is still rare. We report here on a ...

We report a case of aneurysmal dilatation of a vitelline vein observed antenatally. Intra-abdominal vascular dilatation was diagnosed on ultrasound examination at 24 weeks' gestation. The relationship with the umbilicus and portal vein suggested the diagnosis of umbilical vein varix. Fetal tolerance remained excellent in spite of a gradual increase ...

Congenital absence of the portal vein is a rare malformation in which mesenteric and splenic venous flow bypasses the liver and drains into various sites in the systemic venous system via an extrahepatic portosystemic shunt. In an 11-year-old girl with congenital absence of the portal vein, the detailed anatomy of ...

Neurovascular injury may occur during ankle arthroscopy. The majority of complications are neurological injuries; however, vascular injuries do exist. Neurovascular structures are especially vulnerable during portal placement and debridement of anterior structures. Routine anteromedial and anterolateral portals are generally accepted to be safe; this is different from the anterocentral portal, ...

We report two unusual complications after a transjugular intrahepatic portosystemic shunt and a biliary stent placement, respectively. One patient with cirrhosis and portal hypertension developed obstructive jaundice secondary to compression of the right hepatic duct by a stent graft placed in the transjugular intrahepatic portosystemic shunt. In another patient, biliary ...

Venous aneurysms of the superior mesenteric vein and portal vein are an uncommon occurrence and often an incidental finding. They can also be associated with hepatocellular disease and portal hypertension. We present CT and ultrasound findings of these entities. The management of venous aneurysms is generally conservative with serial imaging.
