Portal-systemic anastomosis in the rat
Journal of Surgical Research, 1974Abstract In 1961, Lee and Fisher reported a reliable technique for making a portacaval shunt in the rat that has proven to be reproducible in the hands of many investigators. Sudden diversion of portal blood from the healthy rat liver causes a transient loss in body weight and specific atrophy of the liver in accord with the decrease in total liver ...

The Journal of Trauma: Injury, Infection, and Critical Care, 1978
Traumatic injuries of the portal venous circulation occur infrequently but often pose management problems. During the past 13 years, 94 patients have been treated at the Ben Taub General Hospital for traumatic injury to the portal venous system, including 37 portal, 45 superior mesenteric, seven splenic, and nine inferior mesenteric venous injuries ...

Portal modules for Groupware systems
Proceedings of the 5th International ICST Conference on Collaborative Computing: Networking, Applications, Worksharing, 2009Groupware Systems become more and more functional and complex. Often many features are integrated in a monolithic interface that should fit all needs. A new trend towards portal systems can provide flexible and user-adaptable environments. This paper therefore presents a new approach for the modularization of collaborative systems.

Portal Systemic Encephalopathy
The Nurse Practitioner, 1984Portal systemic encephalopathy is a neuropsychiatric disorder that occurs secondary to chronic liver disease. It is a chronic and disabling disorder that must be treated concurrently with liver disease. In chronic liver disease, the regenerative capacity of the liver to produce new cells is eventually hampered and scar tissue develops. Scarring reduces

Calcification in the liver and portal system
Clinical Radiology, 1967Calcification in the portal system and liver is uncommon. The authors describe 3 patients in whom portal calcification was found. This was associated with cirrhosis in 1 patient and portal hypertension due to thrombosis of the portal vein in the other 2. The authors also observed 3 patients with calcification in the liver.

Portal-systemic shunting and portal-systemic encephalopathy: A predictable relationship
Hepatology, 1995Objective Results of the first prospective randomized clinical trial comparing partial and total portacaval shunt for variceal hemorrhage are reported. Summary Background Data Total portacaval shunts produce subnormal portal pressures, completely diverting hepatic portal flow.

Trauma to the Portal Venous System
Southern Medical Journal, 1975During a 16-year period, 47 wounds of the portal and/or superior mesenteric veins were encountered. Overall mortality was 57%. Survival was greatest in patients with injury to the superior mesenteric vein, wounds repairable by lateral phleborrhaphy, absence of associated major vascular trauma, and only transient or minimal hypovolemic shock.

A Retropancreatic Portal-Systemic Shunt for Portal Hypertension in Children
Archives of Surgery, 1967CHILDREN with bleeding esophaegeal varices secondary to an extrahepatic block of the portal vein present a particularly difficult problem to the surgeon. A splenorenal shunt generally will not provide adequate portal decompression because of the small diameter of the splenic vein.

Wounds of the portal venous system
World Journal of Surgery, 1982AbstractDuring a 23‐year interval, 83 patients with wounds of the portal and/or superior mesenteric veins underwent emergency laparotomy. Six (7%) of the injuries were due to blunt trauma, while penetrating wounds accounted for the remaining 77 (93%).

Hyperprolactinemia in portal systemic encephalopathy
Digestive Diseases and Sciences, 1981The accumulation of false neurotransmitters such as octopamine and depletion of true neurotransmitters such as dopamine have been purported to play a pathogenetic role in portal systemic encephalopathy (PSE). Therefore, we measured plasma prolactin, a known sensitive indicator of functional dopamine activity in man, in an attempt to evaluate ...
