Non-cirrhotic portal hypertension is an unusual but potentially serious liver disorder in human immunodeficiency virus-infected patients with prolonged exposure to didanosine. Due to its rarity, the diagnosis is often delayed. It is postulated that didanosine contributes to obliterative portal venopathy and causes portal hypertension. Affected patients may present with abnormal liver function o...

Portal hypertension is the main cause of complications in patients with cirrhosis. However, evaluating the development and progression of portal hypertension represents a challenge for clinicians. There has been considerable focus on the potential role of noninvasive markers of portal hypertension that could be used to stratify patients with respect to the stage of portal hypertension and to mo...

Non cirrhotic portal fibrosis (NCPF) is a syndrome of obscure etiology, characterized by obliterative portal venopathy leading to portal hypertension, massive splenomegaly and well tolerated episodes of variceal bleeding in young adults, having near normal hepatic function. The lesion in NCPF is generally vascular, present in portal vein, it’s branches or in the presinusoidal area of liver. NCP...

Portal hypertension, a major hallmark of cirrhosis, is defined as a portal pressure gradient exceeding 5 mm Hg. In portal hypertension, porto-systemic collaterals decompress the portal circulation and give rise to varices. Successful management of portal hypertension and its complications requires knowledge of the underlying pathophysiology, the pertinent anatomy, and the natural history of the...

Pulmonary hypertension is well described in association with portal hypertension of any cause including end stage primary biliary cirrhosis (PBC). The essential feature of this association is the presence of portosystemic shunting, including surgically created shunts. A patient with primary pulmonary hypertension and PBC without portal hypertension is reported. This suggests that primary pulmon...

BACKGROUND AND AIMS Nitro-oxidative stress may have pathophysiological consequences. The study aimed to assess the nitro-oxidative stress, the vascular growth factor, and metalloproteinase-9 levels in patients with noncirrohic and cirrhotic portal hypertension. METHODS Patients with noncirrhotic portal hypertension (n=50) and cirrhotic portal hypertension (n=50) from the 3rd Medical Clinic in...

There is conflicting evidence concerning the effects of portal hypertension on the gastric mucosa. This paper summarises the histological and haemodynamic alterations which are present in both human and experimental portal hypertension. Despite the fact that histological studies suggests that the gastric mucosa is an oedematous plethoric structure in portal hypertension, haemodynamic studies sh...

BACKGROUND AND OBJECTIVE Symmers periportal fibrosis secondary to schistosomiasis is a common cause of portal hypertension worldwide. Data on the prevalence of gastric varices and portal hypertensive gastropathy in this group of patients with portal hypertension is relatively scarce. The aim of this study was to determine the prevalence of gastric varices and portal hypertensive gastropathy in ...

Portal hypertension leading to gastric polyposis has rarely been reported. More common gastric manifestations of portal hypertension are portal hypertensive gastropathy and gastric antral vascular ectasia (GAVE). We report a case of a patient in whom portal hypertension manifested as bleeding gastric polyps leading to transfusion-dependent iron deficiency anemia.
