EHPVO is an important cause of non-cirrhotic portal hypertension in third world countries. The most common site of block is at the portal vein formation [90%]. EHPVO is a condition in which there is a block of the major vessel that supplies blood to the liver i.e. the portal vein. This vein carries all absorbed nutrients from .

Thirty five of these 44 patients had elevated serum bilirubin and alkaline phosphatase.

Portal cavernoma compressing the bile duct Apropos of three cases. Two patients were first diagnosed as extrahepatic cholestasis, another had recurrent cholangitis and another five had icterus on clinical examination.
Bayraktar et al, studied biochemical consequences of cavernous transformation of the portal vein due to various etiologies. Eight patients presented with jaundice, two had abdominal pain and one cholangitis. Biliary changes in extrahepatic portal venous obstruction: Symptomatic biliopathy Ouclin et al reported two cases of obstructive jaundice with markedly dilated collateral veins either in or around the bile duct in the setting of extrahepatic portal vein obstruction.
Myeloproliferative disorders in portal vein thrombosis in whpvo. One of the 11 patients with noncirrhotic portal fibrosis had a dilated hepatic ducts. Table 3 shows the details of endoscopic and surgical procedures done on these patients.
Ultrasonography detected gallbladder varices 11 and choledochal varices 9 in patients with extrahepatic portal veinous obstruction.
Detailed prothrombotic profiles were available in 24 patients, including: Portal hypertension represents dhpvo dynamic and intricate interaction between the compensatory mechanisms of the body and the prevalent pathology.
These changes are most commonly seen in patients with extrahepatic portal vein obstruction.
Studies in ehpvoo have shown that hereditary or acquired coagulation disorders do not play a role in the pathogenesis of EHPVO in children. Noncirrhotic portal hypertension pathophysiology and treatment.
Management of extra hepatic portal venous obstruction (EHPVO): current strategies.
It was concluded that gall bladder varices caused some gallbladder stasis but did not impair ehlvo function. Portal biliopathy refers to abnormalities in biliary ductal walls due to portal hypertension. Patients with portal vein obstruction and portal hypertension associated with chronic liver disease and patients without portal vein obstruction were excluded from the analysis.
The papilla and pancreatic duct was normal in all ehpv patients. NIL, Conflict of Interest: One patient died at the age of 40 years, due to cholangitis and sepsis.
In magnetic resonance MR portography, all three patients had cavernous transformation. The next ehpvk is the awareness of the lump in the left side of the abdomen. Bile stasis may result in increased incidence of choledocholithiasis and cholelithiasis. Bull PGI ; Table 2 shows the results of laboratory investigations of patients. Based on the results of the study, persistent cholangitis and gall stones were concluded cause for the development ehpvvo portal vein obstruction accompanied by intrahepatic stones.
This is an indication for surgery. Asymptomatic biliopathy Bayraktar et al, studied biochemical consequences of cavernous transformation of the portal vein due to various etiologies. Such patients generally present with repeated well tolerated episodes of hematemesis and massive splenomegaly.
This may require surgical treatment. Two of these patients were treated using portosystemic shunting and other received biliary ehpov. In our study, only 10 patients Non cirrhotic portal fibrosis NCPF has been reported from all over the world.
ebpvo The postulated mechanisms of biliary abnormalities in EHPVO are extrinsic compression by collaterals and ischemic injury due to venous thrombosis.
It is more frequent in adults than in children.
