Bleeding from ectopic varices, which is rare in patients with portal hypertension, is generally massive and life-threatening. Forty-three patients were hospitalized in our ward for gastrointestinal bleeding from ectopic varices. The frequency of ectopic varices was 43/1218 (3.5%) among portal hypertensive patients in our ward. The locations of the ectopic varices were rectal in thirty-two, duod...

Portacaval shunt operations were done in 15 of 18 patients who were treated surgically for portal hypertension. In eight cases the shunt was established by splenorenal anastomosis; in seven by anastomosis of the portal vein to the side of the inferior vena cava. Of the eight patients with splenorenal shunt, two are well, four are considered improved, and two have died. Of the seven in whom the ...

POSTERIOR PITUITARY EXTRACT is known to lower the portal venous pressure in animalsl-3 and in man a similar effect has been demonstrated during the control of bleeding from esophageal varices with intravenous pitressin.44 It has been suggested that pitressin lowers portal pressure by increasing splanchnic resistance.7 The present communication concerns the effects of intravenous pitressin on sp...

To evaluate the effect of portal hypertension and diminished portal venous blood flow to the liver on hepatic regeneration, male rats were subjected to partial portal vein ligation and subsequently to a two-thirds partial hepatectomy. The levels of ornithine decarboxylase activity at 6 h after partial hepatectomy were greater (p less than 0.001) in the rats with prior partial portal vein ligati...

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 ...

Contents of a website can be constructed by two means. Conventional websites usually have a sitemap initially. Using this map as a blueprint, the website designers develop the pages of the content and add links to the content of a website, such as the I-Know'05 homepage. For the website known as a knowledge portal, a sitemap cannot be prepared to outline the contents in advance. A knowledge por...

In the last ten years new techniques, such as percutaneous ethanol injection (PEI) and radiofrequency ablation (RFA), have been developed for the treatment of hepatocellular carcinoma (HCC). Portal vein involvement is a complication of HCC and the role of surgical resection for HCC with tumor thrombi in the portal veins is controversial. Here we present the case of a 58-year-old man, with Child...

INTRODUCTION We report for the first time a unique case of VACTERL (vertebral anomalies, anal atresia or imperforate anus, cardiac anomalies, tracheoesophageal fistula, renal and limb defect) spectrum associated with portal hypertension. The occurrence of both VACTERL spectrum and extrahepatic portal hypertension in a patient has not been reported in the literature. We examined whether or not t...

Splanchnic organ blood flow and cardiac output were measured by the microsphere method in fasted rats with prehepatic portal hypertension due to portal vein stenosis, in rats with intrahepatic portal hypertension due to bile duct ligation, and in unoperated normal rats. Portal venous pressure was higher in both groups of portal hypertensive rats than in normal rats. Cardiac output was significa...

conclusions in our population of cirrhotic patients, treatment of variceal bleeding predisposed the patients to portal vein thrombosis, but hypercoagulable disorders by themselves were not associated with portal vein thrombosis. results there was no statistically significant difference in the assessed hypercoagulable states between patients with or without portal vein thrombosis. a history of p...
