Portal circulation and portal hypertension.
During the last 25 years, there have been important developments in visualising the portal vein, in examining its contents, and in measuring the pressure of blood flowing within it. Radiologists have set the scene and now is the time of the scanner. These technical advances have been applied to the diagnosis and treatment of patients with portal hypertension, and many ingenious surgical techniq...
متن کاملThe circulation in portal hypertension.
While increased resistance to portal blood flow is a central feature of portal hypertension, the varied clinical presentations of this syndrome and their relation to the underlying divergent splanchnic hemodynamic patterns remain puzzling. Some patients present with massive ascites, repeated hemorrhage from ruptured esopha-geal varcies, and severe hypersplenism, whereas others with equivalent o...
متن کاملSURGICAL EXPERIENCE WITH PORTAL HYPERTENSION DUE TO HEPATOPORTAL SCLEROSIS (NONCIRRHOTIC PORTAL FIBROSIS)
Hepatoportal sclerosis or idiopathic portal hypertension has a worldwide distribution with prevalence in developing and temperate countries. Of 64 patients with this disease seen during a twelve year period, 36 underwent splenectomy or a shunt procedure. The indications for surgical intervention were severe hypersplenism and persistent left upper abdominal pain andlorhistory of frequent ep...
متن کاملHyperdynamic circulation in portal-hypertensive rat model: a primary factor for maintenance of chronic portal hypertension.
Two dissimilar hemodynamic hypotheses, the "backward flow" theory and the "forward flow" theory, have been advanced to define splanchnic hemodynamics in portal hypertension. An animal model with portal hypertension and high-grade portal-systemic shunting, the portal vein-stenotic rat, was studied to determine whether a hemodynamic picture compatible with either theory would develop. Splanchnic ...
متن کاملPortal Hypertension
Introduction Portal hypertension (PHT) may be caused by a wide variety of conditions, each with a different natural history. It frequently presents with bleeding from oesophageal varices, which is the commonest cause of serious upper gastrointestinal haemorrhage in children. Precise diagnosis, a sound understanding of the therapeutic options, and a multidisciplinary approach are essential for s...
