SURGICAL 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 کاملSuperoxide dismutase gene transfer reduces portal pressure in CCl4 cirrhotic rats with portal hypertension.
BACKGROUND Increased intrahepatic vascular tone in cirrhosis has been attributed to a decrease of hepatic nitric oxide (NO) secondary to disturbances in the post-translational regulation of the enzyme eNOS. NO scavenging by superoxide (O(2)(-)) further contributes to a reduction of NO bioavailability in cirrhotic livers. AIM To investigate whether removing increased O(2)(-) levels could be a ...
متن کاملPortal vein prostacyclin activity in experimental portal hypertension in rats.
1. Portal hypertension was produced experimentally in rats by partial ligation of the portal vein. 2. One week later portal veins of these animals were shown to release significantly greater amounts of prostacyclin than control animals. 3. It is postulated that if this response occurs in man, local vasodilatation and inhibition of platelet aggregation may be exacerbatory factors in the severity...
متن کاملChronic administration of octreotide ameliorates portal hypertension and portal hypertensive gastropathy in rats with cirrhosis.
1. Portal hypertension and hyperdynamic circulation have been postulated to play a role in the pathogenesis of portal hypertensive gastropathy. Administration of octreotide to portal hypertensive rats has been shown to reduce portal pressure and ameliorate hyperdynamic circulation. 2. This study investigated the effects of chronic administration of octreotide on systemic and portal haemodynamic...
متن کاملPortal hypertension with visceral leishmaniasis.
We conducted this study to observe evidence of portal hypertension in children with visceral leishmaniasis (VL). Eighty-eight consecutive cases (50 male) of VL were subjected to ultrasonography. Those with evidence of portal hypertension also underwent upper gastrointestinal endoscopy and liver biopsy. Eight patients had portal hypertension as evidenced by dilated caliber of portal and splenic ...
