Treatment of extrahepatic portal hypertension following a whipple procedure with a rex shunt: Report of a case.
Summary of "Treatment of extrahepatic portal hypertension following a whipple procedure with a rex shunt: Report of a case."
The Rex shunt is a mesenteric vein to left portal vein decompressive shunt used for the treatment of portal vein thrombosis and portal hypertension. Its use has been reported primarily in the pediatric population where portal vein thrombosis occurs with some frequency. The shunt is thought to represent a more physiologic shunt, since it restores hepatopedal blood flow through the liver. This report describes the use of this shunt in an adult who had frequent gastrointestinal bleeding secondary to extrahepatic portal vein thrombosis, which occurred as a complication after a pancreaticoduodenectomy.

The meso-Rex shunt is used to safely and effectively treat patients with portal hypertension due to extrahepatic portal vein obstruction. In the standard meso-Rex shunt technique, the patient's own in...
The term portal biliopathy (PB) is used to describe the biliary abnormalities associated with portal hypertension. Between 5% and 30% of patients with PB develop biliary obstruction. We report on a pa...
Extrahepatic portal venous obstruction (EHPVO) is the most common cause of pediatric portal hypertension. We analyzed the investigative protocol and results of portosystemic shunts in this group of pa...
A major cause of cirrhosis related morbidity and mortality is the development of variceal bleeding, a direct consequence of portal hypertension. Less common causes of gastrointestinal bleeding are pep...
Background. The purpose of this study was to evaluate the safety and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) placement in the management of portal hypertension in noncirrhotic...
This study is to evaluate the role of probiotics in the treatment of portal hypertension. In particular the role of probiotics on gut microbiota in liver cirrhosis patients will be studied...
Investigate vasoactive medicators in portal hypertension on stored sera
The investigators will address the hypothesis that portal hypertension is mediated in part by bacterial or endotoxin translocation and the production of inflammatory mediators (tumor necro...
Chronic liver diseases are often characterized by portal hypertension, a major complication involving haemodynamic changes due to increased intrahepatic vascular resistance. It has become ...
The objective of this study is to evaluate the pre-operative symptoms and medical history of patients with portal hypertension who have undergone placement of H-graft portacaval shunts and...
Medical and Biotech [MESH] Definitions
Dilated blood vessels in the ESOPHAGUS or GASTRIC FUNDUS that shunt blood from the portal circulation (PORTAL SYSTEM) to the systemic venous circulation. Often they are observed in individuals with portal hypertension (HYPERTENSION, PORTAL).
Abnormal increase of resistance to blood flow within the hepatic PORTAL SYSTEM, frequently seen in LIVER CIRRHOSIS and conditions with obstruction of the PORTAL VEIN.
Surgical venous shunt between the portal and systemic circulation to effect decompression of the portal circulation. It is performed primarily in the treatment of bleeding esophageal varices resulting from portal hypertension. Types of shunt include portacaval, splenorenal, mesocaval, splenocaval, left gastric-caval (coronary-caval), portarenal, umbilicorenal, and umbilicocaval.
A syndrome characterized by the clinical triad of advanced chronic liver disease, pulmonary vascular dilatations, and reduced arterial oxygenation (HYPOXEMIA) in the absence of intrinsic cardiopulmonary disease. This syndrome is common in the patients with LIVER CIRRHOSIS or portal hypertension (HYPERTENSION, PORTAL).
Functional KIDNEY FAILURE in patients with liver disease, usually LIVER CIRRHOSIS or portal hypertension (HYPERTENSION, PORTAL), and in the absence of intrinsic renal disease or kidney abnormality. It is characterized by intense renal vasculature constriction, reduced renal blood flow, OLIGURIA, and sodium retention.
